THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 549/2004 of the European Parliament and of the Council of 10 March 2004 laying down the framework for the creation of the single European sky (the framework Regulation)OJ L 96, 31.3.2004, p. 1 . and in particular Article 11(6) thereof,

Having regard to Regulation (EC) No 550/2004 of the European Parliament and of the Council of 10 March 2004 on the provision of air navigation services in the single European skyOJ L 96, 31.3.2004, p. 10 . , and in particular Article 15(4) thereof,

This Regulation lays down the measures for the functioning of the performance and charging schemes for air navigation services and network functions.

This Regulation applies to the provision of air navigation services and network functions for general air traffic within the International Civil Aviation Organization (ICAO) European (EUR) region, where Member States are responsible for the provision of air navigation services.

This Regulation applies to:

(a) the air navigation service providers referred to in Article 2(5) of Regulation (EC) No 549/2004;

(b) the body nominated by the Commission to perform the tasks necessary for the execution of the network functions (the Network Manager) in accordance with Article 6(2) of Regulation (EC) No 551/2004 and appointed in accordance with Article 4 of Implementing Regulation (EU) 2019/123.

This Regulation also applies, for the purpose of target setting and performance monitoring on cost-efficiency, to the authorities or entities incurring eligible costs to be recovered through user charges, as specified in point (b) of Article 15(2) of Regulation (EC) No 550/2004 and in the third subparagraph of Article 22(1) of this Regulation.

This Regulation applies to terminal air navigation services provided at airports located within the territories of the Member States with 80000 instrument flight rules (IFR) air transport movements or more per year.

Member States may decide to apply the provisions of this Regulation also to terminal air navigation services provided at other airports located within their respective territories than the ones referred to in paragraph 3.

Member States may decide to apply the provisions of this Regulation also to:

(a) air navigation services and network functions provided in airspace under their responsibility within other ICAO regions than the ICAO EUR region, without prejudice to the rights and duties of Member States under the 1944 Chicago Convention on international civil aviation (the Chicago Convention);

(b) providers of air navigation services having the permission to provide air navigation services without certification, in accordance with Article 7(5) of Regulation (EC) No 550/2004.

Member States shall, without delay, inform the Commission of any decision taken pursuant to paragraph 4 or 5.

Member States shall ensure that the duration of those decisions corresponds to the duration of a reference period. They shall not amend or withdraw those decisions during a reference period.

This Regulation shall apply to the third reference period as set out in Article 7 and to the subsequent reference periods.

OJ L 96, 31.3.2004, p. 1 .

(1) The performance scheme referred to in Article 11 of Regulation (EC) No 549/2004 should improve the performance of air navigation services and network functions in the single European sky.

(2) The charging scheme for air navigation services referred to in Article 15 of Regulation (EC) No 550/2004 is instrumental to the successful implementation of the performance scheme and should therefore complement it. The charging scheme should contribute to greater transparency in the determination, imposition and enforcement of charges to airspace users and should contribute to the cost efficiency of providing air navigation services and to efficiency of flights, while maintaining an optimum safety level. The charging scheme should be consistent with the Eurocontrol's charging system for en route charges and with Article 15 of the 1944 Chicago Convention on International Civil Aviation (the Chicago Convention).

(3) In the interest of clarity, and in order to provide for an adapted regulatory framework for the third reference period of the performance scheme, it is necessary to revise the implementing rules governing the performance and charging schemes contained in Commission Implementing Regulation (EU) No 390/2013Commission Implementing Regulation (EU) No 390/2013 of 3 May 2013 laying down a performance scheme for air navigation services and network functions (OJ L 128, 9.5.2013, p. 1 ). and Commission Implementing Regulation (EU) No 391/2013Commission Implementing Regulation (EU) No 391/2013 of 3 May 2013 laying down a common charging scheme for air navigation services (OJ L 128, 9.5.2013, p. 31 ). and to consolidate these provisions in a single Implementing Regulation.

(4) In accordance with Article 11(1) of Regulation (EC) No 549/2004, the performance scheme should cover air navigations services and network functions referred to in Article 6 of Regulation (EC) No 551/2004 of the European Parliament and of the CouncilRegulation (EC) N o 551/2004 of the European Parliament and of the Council of 10 March 2004 on the organisation and use of the airspace in the single European sky (the airspace Regulation) (OJ L 96, 31.3.2004, p. 20 ). . Therefore, this Regulation should apply to the Network Manager appointed in accordance with Article 4(3) of Commission Implementing Regulation (EU) 2019/123Commission Implementing Regulation (EU) 2019/123 of 24 January 2019 laying down detailed rules for the implementation of air traffic management (ATM) network functions and repealing Commission Regulation (EU) No 677/2011 (OJ L 28, 31.1.2019, p. 1 ). .

(5) The performance and charging schemes should enhance the performance of air navigation services through a gate-to-gate approach covering both en route and terminal air navigation services. They should foster long-term improvements in the performance of air navigation services, as reflected in the European ATM Master PlanAs defined in Article 3 of Commission Implementing Regulation (EU) No 409/2013 of 3 May 2013 on the definition of common projects, the establishment of governance and the identification of incentives supporting the implementation of the European Air Traffic Management Master Plan Text with EEA relevance (OJ L 123, 4.5.2013, p. 1 ). while having due regard to the overriding safety objectives. The performance scheme should contribute to the reduction of greenhouse gas emissions from aviation and should allow optimum use of airspace, taking into account air traffic flows in the European airspace.

(6) A Performance Review Body upon Commission's request may give independent advice to the Commission in all areas that affect the performance of air navigation services and network functions in the Union.

(7) National supervisory authorities should be able to obtain from all relevant parties, including air navigation service providers under their supervision, relevant data necessary for the purpose of ensuring the proper implementation and oversight of this Regulation at a local level. Air navigation service providers should facilitate inspections and surveys carried out by the national supervisory authorities for the purpose of monitoring the implementation of the performance and charging schemes.

(8) The Network Manager should provide relevant inputs to target setting at Union, national and functional airspace block levels, and should support the achievement of performance targets through measures and processes provided in the Network Operations Plan.

(9) In implementing the performance scheme, the Commission and Member States should coordinate with the European Union Aviation Safety Agency in order to ensure that safety aspects are properly addressed, in line with the safety objectives and requirements stemming from Regulation (EU) 2018/1139 of the European Parliament and of the CouncilRegulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018 on common rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations (EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC) No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91 (OJ L 212, 22.8.2018, p. 1 ). .

(10) The duration of a reference period for the performance scheme should be such as to provide the certainty required to implement multi-annual capital expenditure programmes in order to achieve the expected return on investments in the form of performance improvements, while still allowing accuracy of forecasting.

(11) Key performance indicators should be defined in the key performance areas of safety, environment, capacity and cost-efficiency. These key performance indicators should be used for the purpose of setting achievable, sustainable, realistic and time-bound performance targets at Union level, national level or functional airspace block level. The key performance indicators should cover both en route and terminal air navigation services, as well as network functions, in order to improve the overall performance of the network.

(12) Union-wide performance targets should be set by the Commission, taking account of the level of performance achieved in the previous reference period or periods and of relevant inputs provided by the Performance Review Body, the Network Manager and the national supervisory authorities. The inputs from national supervisory authorities should include in particular initial cost and information about traffic forecasts for the reference period concerned. The Commission should substantiate Union-wide performance targets with a description of underlying assumptions and rationales. Drafting of the Union-wide performance targets should be subject to stakeholder consultation.

(13) Member States should be able to decide on whether their respective performance plans are established at national level or at the level of functional airspace blocks, taking account of local circumstances.

(14) National supervisory authorities should be responsible for the development of national or functional airspace block performance plans, including binding performance targets, based on key performance indicators applied at national level or at the level of functional airspace block. The national or functional airspace block performance plans should include initiatives to support cross-border cooperation between air navigation service providers, irrespective of their geographical scope.

(15) Performance plans should provide full transparency on the determined costs of new and existing investments in respect of the purchase, development or leasing of fixed assets. Major investments should be detailed and justified, as well as consistent with SESAR deployment and with expected performance gains.

(16) Consultations should take place at national or functional airspace block level in order to ensure that the views of stakeholders are taken into account in the establishment of performance plans and targets contained therein.

(17) Given the strong links between the different key performance areas, the interdependencies between performance targets should be duly taken into account for the purposes of target setting, having regard to the overriding safety objectives.

(18) Performance targets should be subject to incentives with a view to encouraging better performance, including the application of a traffic risk sharing mechanism in respect of the key performance area of cost-efficiency. Incentive schemes should be effective and should set parameters in a non-discriminatory and transparent manner for the purpose of rewarding or penalising actual performance in relation to the adopted performance targets. The safety key performance area should not be subject to any incentives due to its overriding nature. Member States should ensure that the implementation of incentive schemes does not adversely impact planned and ongoing investments aimed at delivering the adequate capacity and flight efficiency to users.

(19) Member States should adopt draft performance plans and submit them to the Commission for the Commission's assessment and review. In this respect, the Commission should first verify whether the performance plans are complete. If the plans are complete, the Commission should assess whether the proposed performance targets contained in the performance plans are consistent with the Union-wide performance targets. If the required consistency cannot be established, the Commission should request Member States to revise their performance plans and targets, or to take corrective measures.

(20) Member States should adopt and publish the final versions of their respective performance plans only after the Commission has found that the national performance targets or performance targets set at the level of functional airspace blocks (FAB performance targets) contained therein are consistent with the Union-wide targets.

(21) The targets set in the draft performance plans should apply during the procedures for the assessment from the start of the reference period and, where appropriate, during the revision of performance targets set at national or functional airspace block level. Upon the adoption of the final performance plans, the performance targets in the key performance area of cost-efficiency should apply retroactively through an adjustment of unit rates in order to ensure that airspace users benefit from performance improvements from the start of the reference period.

(22) Member States should request permission from the Commission if they want to revise one or several performance targets during a reference period. Such a request can be made where alert thresholds are reached, or where the Member State demonstrates that the initial data, assumptions and rationales, including on investments, underpinning the performance targets are to a significant and lasting extent no longer accurate due to circumstances that were unforeseeable at the time of the adoption of the performance plan. The Commission should authorise the Member State concerned to proceed with the intended revision only if it is necessary and proportionate in light of the aforementioned circumstances, and where the revised performance targets ensure that consistency with the Union-wide performance targets is maintained.

(23) The introduction of new technologies and business models to stimulate integrated service provision should lead to significant cost reductions to the benefit of users over time but can lead to initial restructuring costs. If a Member State demonstrates that restructuring measures bring a net benefit to users, it should also be able to request a revision of local cost-efficiency targets in order to recover the associated restructuring costs through a revision of the determined costs contained in their performance plans, subject to the Commission's authorisation.

(24) The Commission should review the Union-wide performance targets during the reference period to determine whether they remain adequate. The Commission should consider a revision of Union-wide performance targets where it is demonstrated during a reference period that these targets are no longer adequate in light of changed circumstances, and that the revision of targets is necessary and proportionate. A revision of Union-wide targets during a reference period should trigger the start of a new reference period, including the establishment of associated performance plans and performance targets set at national or functional airspace block level.

(25) Network functions should also be subject to performance targets and should contribute to the achievement of the Union-wide performance targets. For this purpose the Network Manager should prepare the Network Performance Plan which should be verified and adopted by the Commission.

(26) An effective operational partnership and cooperative decision making between the principal stakeholders, such as air navigation service providers, functional airspace blocks, airports, civil and military airspace users and the Network Manager is of key importance for the achievement of performance targets of network functions.

(27) The determined costs of air navigation services should be financed by charges imposed on airspace users. These charges should be levied in charging zones established for en route and terminal air navigation services. Member States should ensure that the geographical scope of these charging zones is clearly defined and that the charging zones are consistent with the provision of air navigation services. It may be necessary to modify a terminal charging zone during a reference period due to changes in the operation of airports.

(28) A cost base for charges, which comprises the determined costs of eligible air navigation services and facilities, should be established for each charging zone. Member States should also be allowed to include in these cost bases the determined costs incurred by their national supervisory authorities as well as other State costs related to the provision of air navigation services.

(29) The determined costs for en route and terminal charges should be established prior to the start of each reference period, as part of the performance plans. These determined costs shall be specified for each calendar year of the reference period concerned. National supervisory authorities should verify that the established determined costs only comprise cost items that are eligible under the performance and charging scheme.

(30) The determined costs included in a cost base for en route or terminal air navigation services should include staff costs, operating costs other than staff costs, depreciation costs, cost of capital, and exceptional costs. Actual costs incurred should be annually reported in accordance with the same categorisation in order to ensure consistency and transparency.

(31) National supervisory authorities should, before the start of each reference period, define the criteria used to allocate costs between en route and terminal services and inform the Commission accordingly. Those criteria should ensure the transparent setting of determined costs and guarantee that there are no cross-subsidies between en route and terminal services.

(32) Member States should annually calculate the unit rates for their en route and terminal charging zones. In calculating the unit rate, Member States should ensure that services or facilities funded through public funds including Union assistance programmes such as the Trans-European transport network, the Connecting Europe Facility and the Cohesion Fund, are not charged to airspace users. In calculating the unit rates, Member States should be allowed to adjust their determined costs for inflation.

(33) The performance and charging scheme should provide for a traffic risk sharing mechanism to incentivise the provision of services. National supervisory authorities should be allowed to adjust the values of the traffic risk sharing parameters as defined in this Regulation in order to take account of local circumstances and to better incentivise the provision of air navigation services. That adjustment should be done after consultation of air navigation service providers and airspace users. However, those adjustments should not reduce the risk exposure of the air navigation service provider or providers concerned in comparison with the default mechanism set out in this Regulation.

(34) Air navigation service providers should bear the cost risk with regard to differences between determined and actual costs, except for a limited number of cost items subject to specific requirements.

(35) Air navigation service providers should not be allowed to generate financial surpluses as a result of the cancellation or postponement of new and existing investments during a reference period. Air navigation service providers should be able to annually adjust the planned major investments during a reference period, subject to a detailed justification and provided that the requested changes are approved by the national supervisory authority concerned. Where the actual costs of new and existing investments exceed the corresponding determined costs over a reference period, national supervisory authorities should be responsible for verifying the detailed justifications provided by air navigation service providers and for authorising any subsequent recovery of additional costs from airspace users. Any material difference in those costs should not be charged to users, unless the national supervisory authority has established that the additional costs were exclusively due to new and existing investments required for operational changes consistent with the implementation of the European ATM Master Plan and in particular SESAR common projects.

(36) Unforeseeable changes in applicable legal provisions or financial conditions may lead, during a reference period, to significant deviations of actual pension costs from the determined pension costs set out in the performance plans. Subject to scrutiny by the national supervisory authority, those cost differences should be passed on to airspace users through unit rate adjustments.

(37) Member States should set annually a unit rate for each charging zone. Member States should be able to set their unit rates collectively, in particular when charging zones extend across the airspace of more than one Member State or when they are parties to a joint route charges system. The Commission should verify that the unit rates submitted by Member States comply with the provisions on unit rate calculation of this Regulation.

(38) The charging scheme should ensure complete and transparent information on the cost bases for charges, actual costs and unit rates. Before the start of a reference period, Member States should consult air navigation service providers, airspace users' representatives, and, where relevant, airport operators and airport coordinators on the planned determined costs, planned investments, service unit forecasts and the charging policy for the reference period concerned. During the reference period, Member States should ensure that these stakeholders are annually consulted on the intended unit rates and on the actual costs incurred in connection with the provision of air navigation services. Member States should make complete and adequate information available to all the consulted entities for the purpose of the consultations.

(39) Member States should be able to decide to modulate air navigation charges to provide incentives to equip aircraft with systems included in the SESAR common projects. Member States should be able to further modulate charges, taking into account the level of congestion of the network in a specific area or on a specific route at specific times, to increase the efficiency of air navigation services and to promote their optimised use.

(40) Member States should be able to collect en route charges collectively through a single charge per flight within a joint route charges system, in order to improve the efficiency of the charging scheme and to reduce the administrative and accounting workload.

(41) Enforcement measures should be provided for in order to ensure the prompt and full payment of air navigation charges by airspace users.

(42) Air navigation charges for any specific flight should be calculated, in respect of each charging zone, as a product of applicable unit rate and the number of service units. The level of charges imposed, in particular on light aircraft, should not discourage the use of facilities and services necessary for safety or the introduction of new techniques and procedures. Member States should cover the costs for the services that air navigation service providers have provided to flights exempted from air navigation charges.

(43) Member States should have the possibility, where there is no historical evidence of operational issues, to apply a simplified charging scheme in order to incentivise air navigation service providers and to reduce the administrative burden for the air navigation service providers and national supervisory authorities concerned.

(44) Where terminal air navigation services or communication, navigation and surveillance services, meteorological services for air navigation and aeronautical information services (CNS, MET and AIS) or ATM data services are provided under market conditions, Member States should be allowed to exempt those services from certain provisions pertaining to the charging scheme and from target setting on cost-efficiency. Member States should be able to establish such market conditions during a reference period.

(45) The provision of adequate data and information by national supervisory authorities, air navigation service providers, airport operators, airport coordinators, airspace users and the Network Manager, is essential for the purpose of performance target setting and monitoring at Union-wide level and at national or functional airspace block level.

(46) The national supervisory authorities should regularly monitor the progress made in achieving the performance targets contained in the performance plans. Where the targets are not met, the Member State or national supervisory authority concerned should apply the appropriate measures that they have defined in order to address the situation.

(47) The Commission should monitor the performance of air navigation services and network functions, and regularly assess the achievement of performance targets. The Commission should present the results of that monitoring annually to the Single Sky Committee.

(48) Without prejudice to confidentiality requirements pertaining to market conditions, the essential information and final reports required under this Regulation should be made publicly available in order to guarantee adequate transparency and enable the proper consultation of stakeholders.

(49) Implementing Regulation (EU) No 390/2013 and Implementing Regulation (EU) No 391/2013 should be repealed with effect from 1 January 2020 , but should continue to apply beyond that date in respect of obligations related to the second reference period.

(50) This Regulation should apply in respect of the third reference period and to the subsequent reference periods. In order to allow for the adoption of Union-wide targets and the preparation and adoption of performance plans before the beginning of the third reference period, this Regulation should apply with immediate effect from the date of its entry into force.

(51) The measures provided for in this Regulation are in accordance with the opinion of the Single Sky Committee,

Article 9 Article 9 Union-wide performance targets 1.At the latest 19 months before the start of a reference period, the national supervisory authorities shall provide to the Commission initial cost data and information about traffic forecasts referred to in point (f) of Article 10(2) related to the upcoming reference period, as inputs for the setting of Union-wide performance targets. 2.At the latest 15 months before the start of a reference period, the Commission shall publish indicative target ranges for the Union-wide performance targets, consisting of the annual minimum and maximum values within which the Commission intends to set the Union-wide performance targets. The Commission shall consult the stakeholders referred to in Article 10(3) of Regulation (EC) No 549/2004, other relevant persons and organisations and, regarding safety aspects, the European Union Aviation Safety Agency on those indicative target ranges. 3.At the latest seven months before the start of a reference period, the Commission shall adopt in accordance with point (a) of Article 11(3) of Regulation (EC) No 549/2004 the Union-wide performance targets for the key performance indicators referred to in Article 8(1). For this purpose, the Commission shall: (a) take account of the relevant inputs from the Performance Review Body, the Network Manager and the national supervisory authorities;(b) use en route traffic forecasts, expressed in terms of IFR movements and in service units and based on the latest available Eurocontrol's Statistics and Forecast Service (STATFOR) base forecast;(c) substantiate each Union-wide performance target with a description of the underlying assumptions and rationale for that target, including the use made of inputs referred to in point (a) of this paragraph, the outcome of the consultation referred to in paragraph 2 and other relevant factual data. 4.Together with the adoption of the Union-wide performance targets, the Commission shall establish: (a) a Union-wide baseline value for determined costs and a Union-wide baseline value for the determined unit cost, for the purpose of setting targets in the key performance area of cost-efficiency for the key performance indicator referred to in point 4.1 of Section 1 of Annex I. Those baseline values shall be calculated in respect to the year preceding the start of the reference period.The baseline value for determined costs shall be estimated by using the actual costs available for the preceding reference period and adjusted to take account of latest available cost estimates, traffic variations and their relation to costs. The baseline value for the determined unit cost shall be derived by dividing the baseline value for the determined costs with the traffic forecast expressed in service units for the year preceding the start of the reference period; (b) alert thresholds beyond which Member States may request a revision of the performance targets contained in performance plans, in accordance with point (a)(i) of Article 18(1). Those alert thresholds shall be based on the following parameters:(i) the deviation of the actual traffic from the traffic forecast over a given calendar year, expressed as a percentage of IFR movements;(ii) the deviation of the actual traffic from the traffic forecast over a given calendar year, expressed as a percentage of service units;(iii) the variation of the reference values as a result of the seasonal updates of the Network Operations Plan pursuant to point (a) of Article 9(4) and Article 9(8) of Implementing Regulation (EU) 2019/123 in comparison to the reference values from the latest version of the Network Operations Plan available at the time of drawing up the performance plan. This variation shall be expressed as a percentage of variation or as a fraction of minutes of en route ATFM delay, depending on the magnitude of the references values; (c) the comparator groups of air navigation service providers with a similar operational and economic environment, for the purposes of assessing performance targets in the key performance area of cost-efficiency.

(1) actual cost means a cost actually incurred in a calendar year for the provision of air navigation services which are subject to certified accounts or, in the absence of such certified accounts, subject to a final audit;

Article 10 Article 10 Performance plans 1.National supervisory authorities shall draw up performance plans, either at national level or at the level of functional airspace blocks. 2.The performance plans shall be drawn up in accordance with the template set out in Annex II and shall include: (a) binding national performance targets or binding FAB performance targets, set on the basis of the key performance indicators referred to in Article 8(2), including a baseline value for determined costs and a baseline value for the determined unit cost for each charging zone, for the purpose of setting targets in the key performance area of cost-efficiency. Those baseline values shall be calculated in respect to the year preceding the start of the reference period.The baseline value for determined costs shall be estimated by using the actual costs available for the preceding reference period and shall be adjusted to take account of latest available cost estimates, traffic variations and their relation to costs. The baseline value for the determined unit costs shall be derived by dividing the baseline value for the determined costs with the latest available traffic forecast expressed in service units for the year preceding the start of the reference period; (b) determined costs for en route and terminal air navigation services set in accordance with points (a) and (b) of Article 15(2) of Regulation (EC) No 550/2004 and with this Regulation;(c) the incentive schemes established in accordance with Article 11, specifying the parameters of the incentive schemes, the modulation mechanism of pivot values referred to in Article 11(3) where applicable, as well as measures aimed at achieving the objectives of those incentive schemes;(d) a description of the main measures aimed at achieving performance targets;(e) a confirmation that it is consistent with the scope of this Regulation pursuant to Article 1 of this Regulation and Article 7 of Regulation (EC) No 549/2004;(f) en route traffic forecasts, expressed in terms of IFR movements and in service units and based on Eurocontrol's STATFOR base forecast;(g) terminal traffic forecasts, expressed in terms of IFR movements and in service units, based on Eurocontrol's STATFOR base forecast;(h) a description of initiatives to support cross-border coordination and the provision of cross-border services which are beneficial to the operational performance or cost-efficiency, or both;(i) information about:(i) major investments;(ii) change management plans for the entry into service of major airspace changes or for ATM system improvements, aimed at minimising any negative impact on the network performance. However, as regards point (f) and (g), national supervisory authorities may decide to use other en route and terminal traffic forecasts than those based on Eurocontrol's STATFOR base forecast. In that case, they shall consult the airspace users' representatives and air navigation service providers concerned and set out the reasons for using the other forecasts in the performance plan. Any differences with the Eurocontrol's STATFOR base forecast shall be related to specific local factors not sufficiently addressed by Eurocontrol's STATFOR base forecast. The same forecasts shall be used for all key performance areas. 3.The performance plans may contain additional performance targets set on the basis of the key performance indicators referred to in Article 8(4). Those targets shall support the achievement of the performance targets referred to in Article 9(3) and in point (a) of paragraph 2 of this Article. 4.In accordance with Article 10(1) and point (b) of Article 11(3) of Regulation (EC) No 549/2004, national supervisory authorities shall consult air navigation service providers, airspace users' representatives and, where relevant, airport operators and airport coordinators on the draft performance plans, including on the performance targets and incentive schemes contained therein. 5.The Network Manager shall draw up the Network Performance Plan. The Network Performance Plan shall be drawn up in accordance with the template set out in Annex III and shall set out: (a) the value added of the Network Manager in support to the activities of Member States, functional airspace blocks, air navigation service providers and civil and military airspace users towards achieving capacity and environment targets, and set out the contribution of the network functions towards achieving the Union-wide performance targets;(b) the performance targets and objectives for the Network Manager and for each network function and the measures aimed at achieving those targets. 6.Where as provided in the fourth subparagraph of point (c) of Article 11(3) of Regulation (EC) No 549/2004 the Commission has revised the Union-wide performance targets, Member States shall revise their performance plans and include revised performance targets in accordance with this Regulation.

Article 11 Article 11 Incentive schemes 1.The incentive schemes contained in the performance plans as adopted by the Member States shall: (a) set out incentives of financial nature for the achievement of the performance targets in the key performance areas of cost-efficiency and capacity in an effective and proportional manner;(b) apply during the entire period covered by the performance plan;(c) be non-discriminatory, transparent and effective;(d) apply to en route and terminal air navigation services. 2.The incentive schemes on performance targets in the key performance area of cost-efficiency shall be governed by Articles 27 and 28. 3.The incentive schemes on performance targets in the key performance area of capacity shall in addition to the principles set out in paragraph 1, meet the following principles: (a) they shall be proportionate to the level of ATFM delay and consist of financial advantages and financial disadvantages having material impact on revenue at risk;(b) they shall be set so that the maximum financial disadvantages are at least equal to the maximum financial advantages;The national supervisory authority shall define the maximum fixed percentages referred to in the second subparagraphs of points 2.1(a) and 2.2(a) of Annex XIII and in the second subparagraphs of points 2.1(b) and 2.2(b) of Annex XIII for the calculation of the financial advantages and disadvantages, subject to consultation of airspace users' representatives and of air navigation service providers concerned. In respect to the maximum fixed percentages referred to in the second subparagraphs of points 2.1(a) and 2.2(a) of Annex XIII for the calculation of the financial advantages, those percentages shall not exceed 2 %; (c) for the purpose of calculating the financial advantages or disadvantages, pivot values shall be used;The national supervisory authority shall decide, before the start of the reference period, whether those pivot values are to be based: (i) on the performance targets at national level, broken down at the level of each individual air navigation service provider; or(ii) on modulated performance targets at national level, broken down at the level of each individual air navigation service provider, set annually by the national supervisory authority for the following year in accordance with point 1 of Annex XIII and subject to consultation of airspace users' representatives and of air navigation service providers concerned. The modulation mechanism shall be defined in the performance plan and shall apply for each year of the reference period and shall not be changed during the reference period. The national supervisory authority shall inform the Commission about the pivot values annually; (d) there shall be a symmetric range around the pivot value set by the national supervisory authority, subject to consultation of airspace users' representatives and of air navigation service providers concerned, to ensure that minor variations in ATFM delay do not lead to any financial advantages or disadvantages;(e) where the actual average ATFM delay per flight in year n is lower than the pivot value set for year n and beyond the range referred to in point (d), this shall result in a financial advantage through an increase of the unit rate in year n+2 in accordance with point 2 of Annex XIII;(f) where the actual average ATFM delay per flight in year n is higher than the pivot value set for year n and beyond the range referred to in point (d), this shall result in a financial disadvantage through a reduction of the unit rate in year n+2 in accordance with point 2 of Annex XIII;(g) for the en route targets in the key performance area of capacity and where the performance plan is established at functional airspace block level, the following provisions shall apply, in additional to the principles referred to in points (a) to (f):(i) the national supervisory authorities concerned shall break down the FAB performance target referred to in point 3.1(a) of Section 2 of Annex I at the level of each individual air navigation service provider concerned, for the purpose of setting incentives at national level. The resulting values shall form the basis for pivot values referred to in point (c);(ii) the national supervisory authorities concerned shall apply the same incentive scheme, in a consistent manner to all air navigation service providers concerned;(iii) pivot values for the functional airspace block shall also be used in addition to pivot values at the level of each individual air navigation service provider referred to in point (i), and shall be based either:on the performance targets at functional airspace block level, or on modulated performance targets at functional airspace block level in accordance with point 1 of Annex XIII and subject to consultation of airspace users' representatives and of air navigation service providers concerned; (iv) by way of derogation from point (c), all national supervisory authorities concerned shall jointly decide on whether the pivot values at the level of each individual air navigation service provider and functional airspace block level are to be modulated or not. This decision shall apply in a uniform manner to all pivot values at the level of each individual air navigation service provider and functional airspace block level, for the entire duration of the reference period;(v) where performance targets at national and functional airspace block level are to be modulated, the same modulation mechanism shall apply to performance targets at national level and functional airspace block level;(vi) where the total en route ATFM delay per flight in year n at the functional airspace block level is higher than the pivot value set for year n referred to in point (iii) and beyond the range referred to in point (d) of paragraph 3, point (e) of paragraph 3 shall not apply and point (f) of paragraph 3 shall apply only to those air navigation service providers for which the actual ATFM delay per flight in year n is higher than the pivot value set for year n and beyond the range referred to in point (d);(vii) where the total en route ATFM delay per flight in year n at the functional airspace block level is lower than the pivot value set for year n referred to in point (iii) and beyond the range referred to in point (d) of paragraph 3, point (f) of paragraph 3 shall not apply and point (e) of paragraph 3 shall apply only to those air navigation service providers for which the actual ATFM delay per flight in year n is lower than the pivot value set for year n and beyond the range referred to in point (d). 4.The incentive schemes contained in the performance plans as adopted by the Member States may also set out incentives of financial nature for the achievement of the performance targets in the key performance area of environment or for the achievement of the additional performance targets referred to in Article 10(3) in line with points (b) and (c) of paragraph 1, provided that they are effective and proportional. Those incentive schemes should be applied in addition to and independently from the incentive schemes referred to in paragraphs 2 and 3. The aggregated financial advantage or financial disadvantage from those incentive schemes shall not exceed 2 % and 4 % of the determined costs of year n respectively.

Article 21 Article 21 Establishment of charging zones 1.Member States shall, in the airspace under their responsibility where air navigation services are provided to airspace users, establish one or more charging zones for the purposes of incurring en route charges (en route charging zone) and one or more charging zones for the purposes of incurring terminal charges (terminal charging zone). Member States shall consult the airspace users' representatives concerned prior to establishing or modifying those zones. Member States shall notify the Commission, and the Central Route Charges Office (CRCO) of Eurocontrol where applicable, about the establishment or modification of those charging zones, at least seven months before the start of the reference period. 2.Member States shall ensure that the geographical scope of charging zones is clearly defined. The charging zones shall be consistent with the provision of air navigation services, and may include services provided by an air navigation service provider established in another Member State in relation to cross-border airspace. 3.Where air traffic services related to the approach and departure of aircraft are provided jointly for a group of airports, Member States may establish a specific terminal charging zone within the terminal area concerned. 4.Where Member States decide to establish en route charging zones or terminal charging zones which extend across the airspace for which more than one Member State is responsible, or where Member States decide to establish a common charging zone, the Member States concerned shall ensure consistent and uniform application of this Regulation to the provision of air navigation services in the airspace concerned. Member States shall, without delay, inform the Commission and the CRCO of Eurocontrol about any such decision. 5.Member States may modify or establish a new terminal charging zone during a reference period, provided that they: (a) consult the airspace users' representatives and air navigation service providers concerned prior to the modification;(b) notify, without undue delay, the Commission and the CRCO of Eurocontrol of the modification;(c) provide the Commission, without undue delay, with all of the following:(i) the relevant cost and traffic data adequately reflecting the situation before and after the modification;(ii) the comments of airspace users' representatives and air navigation service providers consulted in accordance with point (a);(iii) an assessment of the expected impact of the modification on the achievement of the national performance targets or FAB performance targets in the key performance area of cost-efficiency and on performance monitoring;(iv) an update of the performance plan with the relevant data. 6.Member States shall not modify an en route charging zone during a reference period.

Article 22 Article 22 Establishment of the cost base for charges 1.The cost base for en route and terminal charges shall consist of the determined costs related to the provision of air navigation services in the charging zone concerned. Determined costs stemming from new ATM systems and major overhauls of existing ATM systems shall only be included in the cost base where those systems are consistent with the implementation of the European ATM Master Plan, and, in particular, with the common projects referred to in Article 15a(3) of Regulation (EC) No 550/2004. Member States may decide to include in the cost base the following determined costs incurred in relation to the provision of air navigation services, in accordance with the second sentence of point (b) of Article 15(2) of Regulation (EC) No 550/2004: (a) determined costs incurred by competent authorities;(b) determined costs incurred by the qualified entities referred to in Article 3 of Regulation (EC) No 550/2004;(c) determined costs stemming from the Eurocontrol International Convention relating to cooperation for the safety of air navigation of 13 December 1960 as last amended. 2.Without prejudice to Article 18, the determined costs included in the cost bases for en route and terminal charges shall be set prior to the start of each reference period as part of the performance plan in real terms and specified for each calendar year of that period in real terms and in nominal terms, with the exception of the determined costs referred to in the third subparagraph of paragraph 1 and the determined costs referred to in points (c) and (d) of paragraph 4, which shall be set in nominal terms where historical cost accounting is applied. 3.Determined costs included in the cost bases for en route and terminal charges shall be calculated in national currency. Where a common charging zone with a single unit rate has been established, the Member States concerned shall ensure conversion of determined costs into a single currency, which may be the euro or another national currency of one of the Member States concerned to ensure a transparent calculation of the single unit rate in application of Article 25(4). 4.The determined costs included in the cost bases for en route and terminal charges shall consist of: (a) staff costs;(b) operating costs other than staff costs;(c) depreciation costs;(d) cost of capital;(e) exceptional costs; As regards point (a), staff costs shall include gross remuneration, overtime payments, and employers' contributions to social security schemes, as well as pension costs and costs of other benefits. Pension costs shall be calculated using prudent assumptions based on the applicable pension scheme or on national law, as appropriate. Those assumptions shall be specified in the performance plan. As regards point (b), operating costs other than staff costs shall include costs incurred for the purchase of goods and services used to provide air navigation services, including outsourced services, material, energy, utilities, rental of buildings, equipment and facilities, maintenance, insurance costs and travel expenses. As regards point (c), depreciation costs shall include costs related to the total fixed assets in operation for the purpose of providing air navigation services. The value of fixed assets shall be depreciated in accordance with their expected operating life, using the straight-line method applied to the costs of the assets being depreciated. Historical or current cost accounting shall be applied for the calculation of the depreciation. The methodology used to calculate depreciation As regards point (d), the cost of capital shall be equal to the product of the following elements: (i) the sum of the average net book value of fixed assets in operation or under construction and possible adjustments to total assets determined by the national supervisory authority and used by the air navigation service provider and of the average value of the net current assets, excluding interest-bearing accounts, that are required for the purposes of providing air navigation services;(ii) the weighted average of the interest rate on debts and of the return on equity. For air navigation service providers without any equity capital, the weighted average shall be calculated on the basis of a return applied to the difference between the total of the assets referred to in point (i) and the debts. For the purpose of establishing the cost of capital, the factors to which weight is to be given shall be based on the proportion of financing through either debt or equity. The interest rate on debts shall be equal to the weighted average interest rate on debts of the air navigation service provider. The return on equity shall be that provided in the performance plan for the reference period and shall be based on the financial risk incurred by the air navigation service provider. Where air navigation service providers incur costs from leasing fixed assets, those costs shall not be included in the calculation of cost of capital. As regards point (e), exceptional costs shall consist of non-recurring costs relating to the provision of air navigation services, including any non-recoverable taxes and customs duties. 5.The determined costs shall be allocated in a transparent way to the charging zones in respect of which they are incurred. Determined costs that are incurred in respect of several charging zones shall be allocated in a proportional way, on the basis of a transparent methodology. To this end, national supervisory authorities shall lay down, before the start of each reference period, the criteria used to allocate determined costs to charging zones, including in respect of points (b) and (c) of this paragraph, and the criteria to allocate the determined costs between en route and terminal services, and shall include this information in the performance plan in accordance with point 3.3(d) of Annex II. The determined costs included in the cost bases for terminal charging zones shall cover the cost of the following services: (a) aerodrome control services or aerodrome flight information services which include air traffic advisory services and alerting services;(b) air traffic services related to the approach and departure of aircraft within a certain distance of an airport which shall be defined on the basis of operational requirements;(c) the proportional part of the air navigation services common to en route and terminal services. 6.The determined costs incurred for flights exempted in accordance with Article 31(3) to (5) shall be composed of: (a) the determined costs of exempted VFR flights, calculated through a marginal cost methodology;(b) the determined costs of exempted IFR flights, calculated as the product of the following elements:(i) the determined costs incurred for IFR flights, which shall consist of the total determined costs less the determined costs of VFR flights;(ii) the ratio of the number of exempted service units to the total number of service units which shall consist of the service units in respect of IFR flights and, where they are not exempted, of VFR flights. The determined costs of exempted VFR flights shall be separated from the determined costs incurred for IFR flights for the purpose of calculating the unit rate. 7.The national supervisory authorities shall verify, in respect of each charging zone, that the cost bases for en route and terminal charges comply with the requirements of Article 15(2) of Regulation (EC) No 550/2004 and with this Article. For this purpose, the national supervisory authorities shall examine the relevant accounting documents, including any asset book and other material relevant to the establishment of the cost base for charges.

Article 23 Article 23 Actual costs

Article 24 Article 24 Transparency of costs 1.Member States shall establish cost bases for charges for each charging zone in a transparent manner. 2.At the latest four months before the start of the reference period, Member States shall, in a coordinated manner, consult air navigation service providers, airspace users' representatives, and, where relevant, airport operators and airport coordinators on the intended establishment of the determined costs included in the cost base for en route and terminal charges, new and existing investments, service unit forecasts and charging policy for the reference period concerned. Member States shall also do so during a reference period, where they intend to request a revision of performance targets in the key performance area of cost-efficiency in accordance with Article 18(1). Member States shall provide the reporting tables and the information required in Annexes VII and IX to the entities invited to the consultation at least three weeks before the consultation. 3.During the reference period, Member States shall on an annual basis, in a coordinated manner, and in accordance with point 1 of Annex XII, consult air navigation service providers, airspace users' representatives, and, where relevant, airport operators and airport coordinators on the actual costs incurred during the previous year and the difference between the actual costs and the determined costs contained in the performance plan. Member States shall provide the reporting table and information required in Annex VII to the entities invited to the consultation at least three weeks before the consultation. 4.Member States shall provide the information referred to in the last subparagraph of paragraphs 2 and 3 to the Commission at the date when it is provided to the consulted parties. Member States shall also inform the Commission about the outcome of the consultation.

Article 25 Article 25 Calculation of unit rates 1.Member States shall calculate the en route and terminal unit rates before the start of each year of the reference period. 2.Those rates shall be calculated by dividing the forecast number of total en route or terminal service units for the relevant year, calculated in accordance with points 1 and 2 of Annex VIII respectively, into the algebraic sum of the following elements: (a) the determined costs, expressed in nominal terms, for the relevant year as set in the performance plan;(b) the adjustments for inflation in accordance with Article 26;(c) the adjustments resulting from the application of the traffic risk sharing mechanism in accordance with Article 27(2) to (5);(d) the adjustments resulting from the application of the cost risk sharing mechanism in accordance with Article 28(4) to (6);(e) the adjustments resulting from the application of the financial incentive schemes in accordance with Article 11(3) and (4);(f) the adjustments resulting from the modulation of air navigation charges in accordance with Article 32;(g) the adjustments resulting from traffic variations, in accordance with Article 27(8);(h) the adjustments resulting from traffic variations, in accordance with Article 27(9);(i) a deduction of other revenue, in accordance with paragraph 3 of this Article;(j) cross-financing between en route charging zones, or between terminal charging zones, in accordance with point (e) of Article 15(2) of Regulation (EC) No 550/2004;(k) adjustments for differences in revenue resulting from the temporary application of the unit rate in accordance with Article 29(5);(l) adjustments relating to previous reference periods. 3.For the purpose of point (i) of paragraph 2, the following revenues of air navigation service providers obtained in year n shall be deducted from the determined costs as other revenue: (a) public funds obtained from public authorities, including financial support from Union assistance programmes;(b) revenue obtained from commercial activities, where the Member State or Member States concerned have decided that those revenues are to be deducted;(c) with regard to terminal air navigation services, revenue obtained from contracts or agreements concluded between air navigation service providers and airport operators, where the Member State or Member States concerned have decided that those revenues are to be deducted. As regards point (a), public funds covering staff costs and other operating costs shall be deducted from the determined costs no later than in year n+2. Public funds covering depreciation costs shall be deducted from the determined costs in accordance with the depreciation schedule of the financed asset (duration and annuity). A Member State may decide not to deduct from determined costs an amount related to the administrative costs incurred for the reporting on the funding agreement if these administrative costs are not included in the cost base for charges. Equally, a Member State may decide not to deduct from determined costs public funds received to cover costs not known at the time of drafting the performance plan and therefore not included in the cost base for charges. Airspace users shall not be charged for the costs covered by public funds. As regards points (b) and (c), the revenue referred to in those points shall be deducted from the determined costs no later than in year n+2. 4.Unit rates shall be calculated in national currency. Where Member States decide to establish a common charging zone in accordance with Article 21(4), the unit rate shall be calculated in a single currency, which may be the euro or another national currency of one of the Member States concerned. The Member States concerned shall notify the Commission and the CRCO of Eurocontrol of the applicable currency.

Article 27 Article 27 Traffic risk sharing mechanism 1.In respect of the incentive schemes referred to in Article 11(2), a traffic risk sharing mechanism shall be applied. Under that mechanism, the risk of revenue changes due to deviations from the service unit forecast set out in the performance plan shall be shared between air navigation service providers and airspace users, in accordance with the provisions of this Article. 2.Where, over a given year n, the actual number of service units deviates from the forecast included in the performance plan for that year n by no more than 2 %, the resulting additional revenue or the resulting revenue loss shall be borne in full by the air navigation service provider or providers concerned. 3.Where, over a given year n, the actual number of service units exceeds the service unit forecast included in the performance plan for that year n by more than 2 %, 70 % of the resulting additional revenue obtained by the air navigation service provider or providers concerned in excess of 2 % of the difference between the actual service units and that forecast shall be passed on to airspace users through adjustments of the unit rates in year n+2. Where, over a given year n, the actual number of service units falls below the service unit forecast included in the performance plan for that year n by more than 2 %, 70 % of the resulting revenue loss incurred by the air navigation service provider or providers concerned in excess of 2 % of the difference between the actual service units and that forecast shall be recovered from airspace users, through adjustments of the unit rates in year n+2. 4.Where, over a given year n, the actual number of service units is lower than 90 % of the service unit forecast included in the performance plan for that year n, the amount of the revenue loss incurred by the air navigation service provider or providers concerned in excess of 10 % of the difference between the actual service units and that forecast shall be recovered in full, from airspace users, through adjustments of the unit rates in year n+2. Where, over a given year n, the actual number of service units exceeds 110 % of the service unit forecast included in the performance plan for that year n, the additional revenue obtained by the air navigation service provider or providers concerned in excess of 10 % of the difference between the actual service units and that forecast shall be passed on in full, to airspace users, through adjustments of the unit rates in year n+2. 5.National supervisory authorities may adapt the values of the parameters of the traffic risk sharing mechanism laid out in paragraphs 2 and 3. When adapting those values, the national supervisory authorities shall: (a) consult on the intended values the airspace users' representatives and air navigation service providers concerned;(b) ensure that the resulting risk exposure of the air navigation service providers is not lower than the maximum revenue at risk under the mechanism laid out in paragraphs 2 and 3;(c) consider the variation of costs of capacity provision by the air navigation service provider concerned due to variation in traffic. 6.The following determined costs shall not be subject to the provisions of paragraphs 2 to 5: (a) the determined costs established in accordance with the third subparagraph of Article 22(1);(b) the determined costs for meteorological services. 7.Member States may exempt from the application of paragraphs 2 to 5 the determined costs of providers of air navigation services which have received permission to provide air navigation services without certification, in accordance with Article 7(5) of Regulation (EC) No 550/2004. 8.In respect of the determined costs referred to in paragraph 6 and, if applicable, in paragraph 7, any additional revenue in year n due to differences between actual service units and the service unit forecast included in the performance plan for that year shall be passed on to airspace users, and any revenue loss shall be recovered from airspace users, through an adjustment of the unit rate in year n+2. 9.The adjustments to the unit rates referred to in points (b), (c), (d), (e), (f), (g), (h), (i), (j), (k) and (l) of Article 25(2) shall not be subject to the provisions of paragraphs 2 to 5. In respect of the adjustments referred to in points (b), (c), (d), (e), (f), (g), (i), (j) and (k) of Article 25(2), any additional revenue in year n due to differences between actual service units and the service unit forecast included in the performance plan for that year shall be passed on to airspace users, and any revenue loss shall be recovered from airspace users through an adjustment of the unit rate in year n+2.

Article 28 Article 28 Cost risk sharing mechanism 1.In respect of the incentive schemes referred to in Article 11(2), a cost risk sharing mechanism shall be applied. Under that mechanism, differences between determined costs included in the performance plan and actual costs shall be shared between air navigation service providers and airspace users, in accordance with the provisions of this Article. 2.The differences referred to in paragraph 1 shall be shared as follows: (a) where, over the whole reference period, actual costs fall below the determined costs, the air navigation service provider or the Member State concerned shall retain in full the resulting difference;(b) where, over the whole reference period, actual costs exceed the determined costs, the air navigation service provider or Member State concerned shall cover in full the resulting difference. 3.Paragraph 2 does not apply if the differences between determined costs and actual costs result from at least one of the following changes: (a) unforeseen changes in costs of new and existing investments;(b) unforeseen changes in costs referred to in the third subparagraph of Article 22(1);(c) unforeseen and significant changes in pension costs established in accordance with Article 22(4) resulting from unforeseeable changes in national pensions law, pensions accounting law or unforeseeable changes in financial market conditions, on the condition that such changes in pension costs are outside the control of the air navigation service provider and, in the case of cost increases, that the air navigation service provider has taken reasonable measures to manage cost increases during the reference period;(d) unforeseen and significant changes in costs resulting from unforeseeable changes in interest rates on loans that finance costs arising from the provision of air navigation services, on the condition that such changes in costs are outside the control of the air navigation service provider and, in the case of cost increases, that the air navigation service provider has taken reasonable measures to manage cost increases during the reference period;(e) unforeseen and significant changes in costs resulting from unforeseeable changes in national taxation law or other unforeseeable new cost items not covered in the performance plan but required by law. The determined costs relating to the costs referred to in this paragraph shall be identified and categorised in the performance plan, in accordance with point 3.3(h) of Annex II. The differences between determined and actual costs referred to in this paragraph shall be identified and explained annually in accordance with Annex VII and Annex IX. 4.In respect of the unforeseen changes in costs referred to in point (a) of paragraph 3, the differences between determined costs and actual costs shall be shared as follows: (a) where, over a calendar year or over the whole reference period, actual costs fall below the determined costs, the air navigation service provider or the Member State concerned shall reimburse the resulting difference to airspace users, through a reduction of the unit rate in year n+2 or in the following reference period, unless, based on a detailed justification of the air navigation service provider, the national supervisory authority decides, after consultation with airspace users' representatives, that the air navigation service provider shall not reimburse a part of the resulting difference;(b) where, over a calendar year or over the whole reference period, actual costs exceed the determined costs by not more than 5 %, Member States may decide that the resulting difference is recovered from airspace users by the air navigation service provider or the Member State concerned, through an increase of the unit rate in year n+2 or in the following reference period, subject to the approval by the national supervisory authority of a detailed justification provided by the air navigation service provider in particular as regards the need to increase capacity and after consultation with airspace users' representatives. Where, during the reference period, air navigation service providers intend to add, cancel or replace major investments with respect to information on major investments identified in the performance plan in accordance with point 2.2(b) of Annex II, these changes shall be approved by the national supervisory authority, after consultation of airspace users' representatives. 5.In respect of the unforeseen changes in costs referred to in point (b) of paragraph 3, the differences between determined costs and actual costs shall be shared as follows: (a) where, over a calendar year, actual costs fall below the determined costs established for that calendar year, Member States shall reimburse the resulting difference to airspace users through a reduction of the unit rate in year n+2;(b) where, over a calendar year, actual costs exceed the determined costs established for that calendar year, Member States shall recover the resulting difference from airspace users through an increase of the unit rate in year n+2. 6.In respect of the unforeseen changes in costs referred to in points (c), (d) and (e) of paragraph 3, the differences between determined costs and actual costs shall be shared as follows: (a) where, over a calendar year or over the whole reference period, actual costs fall below the determined costs, the air navigation service provider or the Member State concerned shall reimburse the resulting difference to airspace users through a reduction of the unit rate in year n+2, in the following reference period or in the following two reference periods if the amounts to be recovered impact the unit rate in a disproportionate manner;(b) where, over a calendar year or over the whole reference period, actual costs exceed the determined costs, Member States may decide that the resulting difference is recovered from airspace users by the air navigation service provider or the Member State concerned, through an increase of the unit rate in year n+2, in the following reference period or in the following two reference periods if the amounts to be recovered impact the unit rate in a disproportionate manner. 7.National supervisory authorities shall verify annually whether air navigation service providers apply correctly the provisions of this Article. National supervisory authorities shall draw up a report by 1 September of year n+1 on the changes in costs referred to in paragraph 3 which occurred in year n. The report shall be subject to consultation of airspace users' representatives.. National supervisory authorities shall also include in the report which is due by 1 September of the year following the final year of the reference period the balance over the whole reference period in respect of the unforeseen changes in the costs referred to in points (a), (c), (d) and (e) of paragraph 3.

Article 29 Article 29 Setting unit rates for charging zones 1.Member States shall set a unit rate for each charging zone on an annual basis in accordance with Article 25. Without prejudice to paragraph 3, unit rates shall not be modified in the course of a year. 2.Member States shall set a unit rate for year n for each charging zone in line with the following requirements: (a) national supervisory authorities shall submit, on behalf of their respective Member State, the calculated unit rate to the Commission and to the CRCO of Eurocontrol by 1 June of year n-1. This submission shall include the reporting tables and additional information set out in Annex VII and Annex IX;(b) before 1 November of year n-1, if needed, national supervisory authorities shall update the calculated unit rate referred to in point (a), following consultation with airspace users. They shall submit this calculated updated unit rate, on behalf of their respective Member State, to the Commission and the CRCO of Eurocontrol, at the latest by 1 November of year n-1;(c) Member States shall set the unit rate for year n at the latest by 20 December of year n-1 and inform the Commission and the CRCO of Eurocontrol of that rate. 3.The Commission shall verify that the unit rates referred to in paragraph 2 are calculated in compliance with the requirements set out in Article 25(2). Where the Commission finds that a unit rate does not comply with the requirements set out in Article 25(2), it shall notify the Member State concerned and invite it to submit a revised unit rate. Where the Commission finds that the revised unit rate are calculated in compliance with the requirements set out in Article 25(2), it shall notify the Member State concerned accordingly. 4.Where, as a consequence of the time needed to complete the procedure referred to in paragraph 3, a unit rate for year n is revised after the start of the year to which it relates and such revision causes a difference in revenues, the unit rate shall be adjusted as follows: (a) a first adjustment of the unit rate in the year following the revision of the unit rate, and(b) a final adjustment of the unit rate two years after that year. 5.If Member States have not adopted a performance plan before the start of the reference period, or where the performance plan is revised in accordance with Article 18 during the reference period, the unit rates shall, where necessary, be recalculated and applied as soon as possible on the basis of the adopted performance plan or adopted revised performance plan. Where a performance plan is adopted after the start of the reference period, any difference in revenue due to the application of the unit rate or unit rates calculated on the basis of the draft performance plan, instead of the unit rate or unit rates calculated on the basis of the adopted performance plan, shall result in a first adjustment of the unit rate in the year following the adoption of the performance plan and a final adjustment of the unit rate two years after that year. The provisions of Articles 27 and 28 shall be applied on the basis of the adopted performance plan and shall apply retroactively as from the first day of the reference period. Where a performance plan is revised during the reference period in accordance with Article 18, any difference in revenue due to the application of the unit rate or unit rates calculated on the basis of the adopted performance plan, instead of the unit rate or unit rates calculated on the basis of the adopted revised performance plan, shall result in a first adjustment of the unit rate in the year following the adoption of the revised performance plan and a final adjustment of the unit rate two years after that year. The provisions of Articles 27 and 28 shall be applied on the basis of the adopted revised performance plan and shall apply retroactively as from the first day of the year to which the revised performance plan applies. 6.By derogation from Article 25(2), Member States may decide to set the unit rate referred to in paragraph 1 at a level lower than the unit rate calculated in accordance with Article 25(2). In that case, they shall include that lower unit rate in the reporting tables on unit rates calculation in accordance with the template of Table 2 of Annex IX. The resulting difference in revenues shall not be recovered from airspace users.

(3) airport coordinator means the natural or legal person appointed by a Member State to carry out the coordination duties at coordinated airports set out in Article 4 of Council Regulation (EEC) No 95/93Council Regulation (EEC) No 95/93 of 18 January 1993 on common rules for the allocation of slots at Community airports (OJ L 14, 22.1.1993, p. 1 ). ;

Article 31 Article 31 Calculation of charges 1.The en route charge for a given flight in a given en route charging zone shall be equal to the product of the unit rate established for that en route charging zone and the en route service units for that flight. 2.The terminal charge for a given flight in a given terminal charging zone shall be equal to the product of the unit rate established for that terminal charging zone and the terminal service units for that flight. For the purpose of calculating the terminal charge, the approach and departure of a flight shall count as a single flight. The unit to be counted shall be either the arriving or the departing flight. 3.Member States shall exempt the following flights from en route charges: (a) flights performed by aircraft with a maximum authorised take-off weight which is less than two metric tons;(b) mixed VFR/IFR flights in the charging zones where they are performed exclusively under VFR and where an en route charge is not levied for VFR flights;(c) flights performed exclusively for the purpose of transport, on official mission, of reigning Monarchs and their immediate family, heads of state, heads of government and government ministers, where it is substantiated by the appropriate status indicator or remark on the flight plan that the flight is performed exclusively for that purpose;(d) search and rescue flights authorised by the appropriate competent body. 4.Member States may exempt the following flights from en route charges: (a) military flights performed by aircraft of a Member State or any third country;(b) training flights performed solely within the airspace of the Member State concerned and exclusively for the purpose of obtaining a licence, or a rating in the case of cockpit flight crew, where it is substantiated by an appropriate remark on the flight plan that the flight is performed exclusively for that purpose;(c) flights performed exclusively for the purpose of checking or testing equipment used or intended to be used as ground aids to air navigation, excluding positioning flights by the aircraft concerned;(d) flights terminating at the airport from which the aircraft has taken off and during which no intermediate landing has been made;(e) VFR flights;(f) humanitarian flights authorised by the appropriate competent body;(g) customs and police flights. 5.Member States may exempt from terminal charges the flights referred to in paragraphs 3 and 4. 6.Member States shall cover the costs for the services that air navigation service providers have provided to flights exempted from en route charges or terminal charges in accordance with paragraph 3, 4 or 5.

Article 32 Article 32 Modulation of air navigation charges 1.Member States may, on a non-discriminatory and transparent basis, modulate air navigation charges for airspace users to: (a) optimise the use of air navigation services;(b) reduce the environmental impact of flying;(c) reduce the level of congestion of the network in a specific area or on a specific route at specific times.(d) accelerate the deployment of SESAR ATM capabilities in anticipation of the time period set out in the common projects referred to in Article 15a(3) of Regulation (EC) No 550/2004, in particular with a view to giving incentives to equip aircraft with systems included in those common projects. Member States shall ensure that modulation of charges in respect of points (a) to (c) of this paragraph does not result in any overall change in annual revenue for the air navigation service provider compared to the situation where charges would not have been modulated. Over- or under recoveries shall result in an adjustment of the unit rate in year n+2. 2.Modulation of air navigation charges shall be applied in respect of the en route charge or the terminal charge, or both. Before the application of the modulation of charges, Member States shall consult airspace users' representatives and air navigation service providers concerned on such intended modulation. 3.National supervisory authorities shall monitor the proper implementation of the modulation of air navigation charges by air navigation service providers and report in accordance with Article 37(1).

Article 33 Article 33 Collection of charges 1.Member States may collect charges through a single charge per flight. Where charges are billed and collected on a regional basis, the billing currency may be the euro and an administrative unit rate for billing and collection costs may be added to the unit rate concerned. 2.Member States shall ensure that the amounts collected on their behalf are used to finance the determined costs in accordance with the provisions of this Regulation. 3.Airspace users shall promptly and fully pay all air navigation charges incurred in accordance with this Regulation. 4.Member States shall ensure that effective, and proportionate enforcement measures for the collection of air navigation charges are applied where necessary. Those measures may include denial of services, detention of aircraft or other enforcement measures in accordance with the law of the Member State concerned.

Article 34 Article 34 Simplified charging scheme 1.Subject to the conditions set out in paragraph 2, Member States may decide to establish and apply a simplified charging scheme for the duration of an entire reference period in respect of: (a) one or more en route and one or more terminal charging zones;(b) one or more air navigation service providers providing services in the charging zone or zones referred to in point (a). 2.Member States may decide to establish and apply a simplified charging scheme referred to in paragraph 1 only if all of the following conditions are met: (a) a Commission decision adopted pursuant to Article 14(2), Article 15(2) or Article 15(4) confirms that the performance targets set by the Member State in the draft performance plan referred to in Article 12 are consistent with the Union-wide performance targets;(b) the performance targets in the key performance areas of safety, capacity and environment have been met in the three years preceding the adoption of the draft performance plan referred to in Article 12;(c) the performance plan includes an incentive scheme on capacity targets as required in Article 11;(d) the air navigation service providers concerned and the airspace users concerned have been consulted on the intended decision and airspace users representing at least 65 % of the IFR flights operated in the airspace where the Member State or Members States concerned are responsible for the provision of air navigation services agree with the intended decision. 3.If Member States decide to establish and apply a simplified charging scheme pursuant to paragraph 2, they shall not apply: (a) the traffic risk sharing mechanism referred to in Article 11(2) and Article 27. By not applying the traffic risk sharing mechanism, the traffic risk is therefore borne in full by the air navigation service provider;(b) the provisions of Article 28(4) to (6) related to the cost risk sharing mechanism;(c) the over or under recoveries resulting from the modulation of air navigation charges pursuant to Article 32. Any carry-over from the years preceding the reference period to which the simplified charging scheme is applied, shall still be taken into account in the calculation of unit rates. 4.If Member States decide to establish and apply a simplified charging scheme pursuant to paragraph 2, they shall specify and substantiate their decision in the performance plan, in accordance with point 1.7 of Annex II.

Where, during a reference period, a Member State decides to apply paragraph 1, it shall also revise its performance plan in accordance with Article 18(1) in respect of the services concerned. 3.A Member State shall decide to apply paragraph 1 only after having completed all of the following steps: (a) its national supervisory authority has found, on the basis of a detailed assessment in accordance with the conditions laid down in Annex X, that the provision of the services concerned is subject to market conditions;(b) it has consulted the airspace users' representatives concerned on the intended decision and on that assessment, and has taken account of their comments where appropriate;(c) it has made its intended decision and that assessment publicly available;(d) it has submitted its intended decision and that assessment to the Commission and received the agreement of the Commission. As regards point (d), the Member State shall submit the assessment no later than 12 months before the start of a reference period or, in the event of an assessment during the reference period, without undue delay upon having completed the assessment. The Commission shall notify the Member State concerned whether it agrees that the assessment has been carried out in accordance with the conditions laid down in Annex X. The Commission shall do so without undue delay. Where necessary, the Commission shall request additional information from the Member State concerned, which that Member State shall provide without undue delay. 4.If a Member State decides to apply paragraph 1, its national supervisory authority shall assess regularly whether the conditions laid down in Annex X continue to be met. If the national supervisory authority finds that those conditions are no longer met, the Member State shall, without undue delay, revoke its decision, after having completed the steps set out in points (b) to (d) of paragraph 3. Upon that revocation, the Member State shall, for the upcoming reference period or, as the case may be, for the remaining duration of the reference period, not apply the exemptions listed in the first subparagraph of paragraph 2 in respect of the services concerned. If the revocation occurs during the reference period, the Member State concerned shall also revise its performance plan in accordance with Article 18(1). 5.If the services subject to the application of paragraph 1 are provided in a common charging zone set up in accordance with Article 21(4), the Member States concerned may decide to establish that the provision of some or all of those services are subject to market conditions only jointly. In that case, they shall jointly ensure that the requirements of this Article are respected. 6.If a Member State decides to apply paragraph 1, it shall submit to the Commission the information specified in Annex XI in the first year of each reference period. The Commission shall not make that information publicly available.

(i) at least one of the alert thresholds referred to in point (b) of Article 9(4) is reached and the national supervisory authority or authorities concerned have assessed the situation and have shown that the resulting effects of reaching the alert threshold or thresholds cannot be sufficiently mitigated unless the performance targets are revised;

(ii) the initial data, assumptions and rationales, including on investments, on the basis of which the performance targets concerned were set are to a significant and lasting extent no longer accurate due to circumstances that were unforeseeable at the time of the adoption of the performance plan, and the national supervisory authority or authorities concerned have assessed the situation and have shown that the resulting effects cannot be sufficiently mitigated unless the performance targets are revised;

(b) the Commission has, based on a reasoned request by the Member State or Member States concerned, decided that:(i) it agrees that the intended revision is necessary and proportionate in light of the occurrence of one or more of the following situations referred to in point (a);(ii) the intended revised performance targets are consistent with the Union-wide performance targets, having assessed those targets on the basis of the criteria laid down in point 1 of Annex IV.

(i) it agrees that the intended revision is necessary and proportionate in light of the occurrence of one or more of the following situations referred to in point (a);

(ii) the intended revised performance targets are consistent with the Union-wide performance targets, having assessed those targets on the basis of the criteria laid down in point 1 of Annex IV.

The Commission shall adopt the decision referred to in point (b) within seven months from the date of the submission of the complete request submitted by the Member State or Member States concerned.

Any revisions of performance targets adopted in application of this Article shall not apply retroactively.

The Network Manager shall submit the draft Network Performance Plan to the Commission after its endorsement by the Network Management Board as referred to in point (o) of Article 18(1) of Implementing Regulation (EU) 2019/123 at the latest three months before the start of the reference period.

The Commission shall assess whether the draft Network Performance Plan meets the criteria laid down in Annex V.

The Commission may request the Network Manager to submit a revision of that draft Network Performance Plan, where this is necessary to ensure compliance with criteria laid down in Annex V.

Where the Commission finds that the draft Network Performance Plan meets the criteria laid down in Annex V, it shall adopt the Network Performance Plan.

The Network Manager shall publish and implement the Network Performance Plan after its adoption by the Commission pursuant to paragraph 3.

Where, as a consequence of the time needed to complete the procedures referred to in paragraphs 2 and 3, the Network Performance Plan has not been adopted by the Commission before the start of the reference period, the most recent version of the draft Network Performance Plan endorsed by the Network Management Board shall apply on a provisional basis, until the Commission adopts the Network Performance Plan.

The determined costs of en route air navigation services shall be financed by en route charges imposed on airspace users and, where Article 25(3) applies, by other revenue as referred to in that Article.

The determined costs of terminal air navigation services shall be financed by terminal charges imposed on airspace users and, where Article 25(3) applies, by other revenue referred to in that Article.

Revenues derived from en route charges or terminal charges shall not be used to finance commercial activities of air navigation service providers.

Member States shall, in the airspace under their responsibility where air navigation services are provided to airspace users, establish one or more charging zones for the purposes of incurring en route charges (en route charging zone) and one or more charging zones for the purposes of incurring terminal charges (terminal charging zone).

Member States shall consult the airspace users' representatives concerned prior to establishing or modifying those zones.

Member States shall notify the Commission, and the Central Route Charges Office (CRCO) of Eurocontrol where applicable, about the establishment or modification of those charging zones, at least seven months before the start of the reference period.

Member States shall ensure that the geographical scope of charging zones is clearly defined. The charging zones shall be consistent with the provision of air navigation services, and may include services provided by an air navigation service provider established in another Member State in relation to cross-border airspace.

Where air traffic services related to the approach and departure of aircraft are provided jointly for a group of airports, Member States may establish a specific terminal charging zone within the terminal area concerned.

Where Member States decide to establish en route charging zones or terminal charging zones which extend across the airspace for which more than one Member State is responsible, or where Member States decide to establish a common charging zone, the Member States concerned shall ensure consistent and uniform application of this Regulation to the provision of air navigation services in the airspace concerned.

Member States shall, without delay, inform the Commission and the CRCO of Eurocontrol about any such decision.

Member States may modify or establish a new terminal charging zone during a reference period, provided that they:

(a) consult the airspace users' representatives and air navigation service providers concerned prior to the modification;

(b) notify, without undue delay, the Commission and the CRCO of Eurocontrol of the modification;

(c) provide the Commission, without undue delay, with all of the following:(i) the relevant cost and traffic data adequately reflecting the situation before and after the modification;(ii) the comments of airspace users' representatives and air navigation service providers consulted in accordance with point (a);(iii) an assessment of the expected impact of the modification on the achievement of the national performance targets or FAB performance targets in the key performance area of cost-efficiency and on performance monitoring;(iv) an update of the performance plan with the relevant data.

(i) the relevant cost and traffic data adequately reflecting the situation before and after the modification;

(ii) the comments of airspace users' representatives and air navigation service providers consulted in accordance with point (a);

(iii) an assessment of the expected impact of the modification on the achievement of the national performance targets or FAB performance targets in the key performance area of cost-efficiency and on performance monitoring;

(iv) an update of the performance plan with the relevant data.

Member States shall not modify an en route charging zone during a reference period.

The cost base for en route and terminal charges shall consist of the determined costs related to the provision of air navigation services in the charging zone concerned.

Determined costs stemming from new ATM systems and major overhauls of existing ATM systems shall only be included in the cost base where those systems are consistent with the implementation of the European ATM Master Plan, and, in particular, with the common projects referred to in Article 15a(3) of Regulation (EC) No 550/2004.

Member States may decide to include in the cost base the following determined costs incurred in relation to the provision of air navigation services, in accordance with the second sentence of point (b) of Article 15(2) of Regulation (EC) No 550/2004:

(a) determined costs incurred by competent authorities;

(b) determined costs incurred by the qualified entities referred to in Article 3 of Regulation (EC) No 550/2004;

(c) determined costs stemming from the Eurocontrol International Convention relating to cooperation for the safety of air navigation of 13 December 1960 as last amended.

Without prejudice to Article 18, the determined costs included in the cost bases for en route and terminal charges shall be set prior to the start of each reference period as part of the performance plan in real terms and specified for each calendar year of that period in real terms and in nominal terms, with the exception of the determined costs referred to in the third subparagraph of paragraph 1 and the determined costs referred to in points (c) and (d) of paragraph 4, which shall be set in nominal terms where historical cost accounting is applied.

Determined costs included in the cost bases for en route and terminal charges shall be calculated in national currency. Where a common charging zone with a single unit rate has been established, the Member States concerned shall ensure conversion of determined costs into a single currency, which may be the euro or another national currency of one of the Member States concerned to ensure a transparent calculation of the single unit rate in application of Article 25(4).

The determined costs included in the cost bases for en route and terminal charges shall consist of:

(a) staff costs;

(b) operating costs other than staff costs;

(c) depreciation costs;

(d) cost of capital;

(e) exceptional costs;

As regards point (a), staff costs shall include gross remuneration, overtime payments, and employers' contributions to social security schemes, as well as pension costs and costs of other benefits. Pension costs shall be calculated using prudent assumptions based on the applicable pension scheme or on national law, as appropriate. Those assumptions shall be specified in the performance plan.

As regards point (b), operating costs other than staff costs shall include costs incurred for the purchase of goods and services used to provide air navigation services, including outsourced services, material, energy, utilities, rental of buildings, equipment and facilities, maintenance, insurance costs and travel expenses.

As regards point (c), depreciation costs shall include costs related to the total fixed assets in operation for the purpose of providing air navigation services. The value of fixed assets shall be depreciated in accordance with their expected operating life, using the straight-line method applied to the costs of the assets being depreciated. Historical or current cost accounting shall be applied for the calculation of the depreciation. The methodology used to calculate depreciation

As regards point (d), the cost of capital shall be equal to the product of the following elements:

(i) the sum of the average net book value of fixed assets in operation or under construction and possible adjustments to total assets determined by the national supervisory authority and used by the air navigation service provider and of the average value of the net current assets, excluding interest-bearing accounts, that are required for the purposes of providing air navigation services;

(ii) the weighted average of the interest rate on debts and of the return on equity. For air navigation service providers without any equity capital, the weighted average shall be calculated on the basis of a return applied to the difference between the total of the assets referred to in point (i) and the debts.

For the purpose of establishing the cost of capital, the factors to which weight is to be given shall be based on the proportion of financing through either debt or equity. The interest rate on debts shall be equal to the weighted average interest rate on debts of the air navigation service provider. The return on equity shall be that provided in the performance plan for the reference period and shall be based on the financial risk incurred by the air navigation service provider.

Where air navigation service providers incur costs from leasing fixed assets, those costs shall not be included in the calculation of cost of capital.

As regards point (e), exceptional costs shall consist of non-recurring costs relating to the provision of air navigation services, including any non-recoverable taxes and customs duties.

The determined costs shall be allocated in a transparent way to the charging zones in respect of which they are incurred. Determined costs that are incurred in respect of several charging zones shall be allocated in a proportional way, on the basis of a transparent methodology.

To this end, national supervisory authorities shall lay down, before the start of each reference period, the criteria used to allocate determined costs to charging zones, including in respect of points (b) and (c) of this paragraph, and the criteria to allocate the determined costs between en route and terminal services, and shall include this information in the performance plan in accordance with point 3.3(d) of Annex II.

The determined costs included in the cost bases for terminal charging zones shall cover the cost of the following services:

(a) aerodrome control services or aerodrome flight information services which include air traffic advisory services and alerting services;

(b) air traffic services related to the approach and departure of aircraft within a certain distance of an airport which shall be defined on the basis of operational requirements;

(c) the proportional part of the air navigation services common to en route and terminal services.

The determined costs incurred for flights exempted in accordance with Article 31(3) to (5) shall be composed of:

(a) the determined costs of exempted VFR flights, calculated through a marginal cost methodology;

(b) the determined costs of exempted IFR flights, calculated as the product of the following elements:(i) the determined costs incurred for IFR flights, which shall consist of the total determined costs less the determined costs of VFR flights;(ii) the ratio of the number of exempted service units to the total number of service units which shall consist of the service units in respect of IFR flights and, where they are not exempted, of VFR flights.

(i) the determined costs incurred for IFR flights, which shall consist of the total determined costs less the determined costs of VFR flights;

(ii) the ratio of the number of exempted service units to the total number of service units which shall consist of the service units in respect of IFR flights and, where they are not exempted, of VFR flights.

The determined costs of exempted VFR flights shall be separated from the determined costs incurred for IFR flights for the purpose of calculating the unit rate.

The national supervisory authorities shall verify, in respect of each charging zone, that the cost bases for en route and terminal charges comply with the requirements of Article 15(2) of Regulation (EC) No 550/2004 and with this Article. For this purpose, the national supervisory authorities shall examine the relevant accounting documents, including any asset book and other material relevant to the establishment of the cost base for charges.

The provisions of Article 22 shall apply mutatis mutandis to the establishment of actual costs.

Member States shall establish cost bases for charges for each charging zone in a transparent manner.

At the latest four months before the start of the reference period, Member States shall, in a coordinated manner, consult air navigation service providers, airspace users' representatives, and, where relevant, airport operators and airport coordinators on the intended establishment of the determined costs included in the cost base for en route and terminal charges, new and existing investments, service unit forecasts and charging policy for the reference period concerned.

Member States shall also do so during a reference period, where they intend to request a revision of performance targets in the key performance area of cost-efficiency in accordance with Article 18(1).

Member States shall provide the reporting tables and the information required in Annexes VII and IX to the entities invited to the consultation at least three weeks before the consultation.

During the reference period, Member States shall on an annual basis, in a coordinated manner, and in accordance with point 1 of Annex XII, consult air navigation service providers, airspace users' representatives, and, where relevant, airport operators and airport coordinators on the actual costs incurred during the previous year and the difference between the actual costs and the determined costs contained in the performance plan.

Member States shall provide the reporting table and information required in Annex VII to the entities invited to the consultation at least three weeks before the consultation.

Member States shall provide the information referred to in the last subparagraph of paragraphs 2 and 3 to the Commission at the date when it is provided to the consulted parties. Member States shall also inform the Commission about the outcome of the consultation.

Member States shall calculate the en route and terminal unit rates before the start of each year of the reference period.

Those rates shall be calculated by dividing the forecast number of total en route or terminal service units for the relevant year, calculated in accordance with points 1 and 2 of Annex VIII respectively, into the algebraic sum of the following elements:

(a) the determined costs, expressed in nominal terms, for the relevant year as set in the performance plan;

(b) the adjustments for inflation in accordance with Article 26;

(c) the adjustments resulting from the application of the traffic risk sharing mechanism in accordance with Article 27(2) to (5);

(d) the adjustments resulting from the application of the cost risk sharing mechanism in accordance with Article 28(4) to (6);

(e) the adjustments resulting from the application of the financial incentive schemes in accordance with Article 11(3) and (4);

(f) the adjustments resulting from the modulation of air navigation charges in accordance with Article 32;

(g) the adjustments resulting from traffic variations, in accordance with Article 27(8);

(h) the adjustments resulting from traffic variations, in accordance with Article 27(9);

(i) a deduction of other revenue, in accordance with paragraph 3 of this Article;

(j) cross-financing between en route charging zones, or between terminal charging zones, in accordance with point (e) of Article 15(2) of Regulation (EC) No 550/2004;

(k) adjustments for differences in revenue resulting from the temporary application of the unit rate in accordance with Article 29(5);

(l) adjustments relating to previous reference periods.

For the purpose of point (i) of paragraph 2, the following revenues of air navigation service providers obtained in year n shall be deducted from the determined costs as other revenue:

(a) public funds obtained from public authorities, including financial support from Union assistance programmes;

(b) revenue obtained from commercial activities, where the Member State or Member States concerned have decided that those revenues are to be deducted;

(c) with regard to terminal air navigation services, revenue obtained from contracts or agreements concluded between air navigation service providers and airport operators, where the Member State or Member States concerned have decided that those revenues are to be deducted.

As regards point (a), public funds covering staff costs and other operating costs shall be deducted from the determined costs no later than in year n+2. Public funds covering depreciation costs shall be deducted from the determined costs in accordance with the depreciation schedule of the financed asset (duration and annuity). A Member State may decide not to deduct from determined costs an amount related to the administrative costs incurred for the reporting on the funding agreement if these administrative costs are not included in the cost base for charges. Equally, a Member State may decide not to deduct from determined costs public funds received to cover costs not known at the time of drafting the performance plan and therefore not included in the cost base for charges. Airspace users shall not be charged for the costs covered by public funds.

As regards points (b) and (c), the revenue referred to in those points shall be deducted from the determined costs no later than in year n+2.

Unit rates shall be calculated in national currency.

Where Member States decide to establish a common charging zone in accordance with Article 21(4), the unit rate shall be calculated in a single currency, which may be the euro or another national currency of one of the Member States concerned. The Member States concerned shall notify the Commission and the CRCO of Eurocontrol of the applicable currency.

For each year of the reference period, the determined costs included in the cost bases for en route and terminal charges of year n expressed in nominal terms shall be adjusted on the basis of the difference in percentage between the actual inflation index and the forecast inflation index for that year n and included as an adjustment for the calculation of the unit rate for year n+2.

The determined costs referred to in the third subparagraph of Article 22(1), and the determined costs referred to in points (c) and (d) of Article 22(4) where historical cost accounting is applied, shall not be subject to any inflation adjustment.

In respect of the incentive schemes referred to in Article 11(2), a traffic risk sharing mechanism shall be applied. Under that mechanism, the risk of revenue changes due to deviations from the service unit forecast set out in the performance plan shall be shared between air navigation service providers and airspace users, in accordance with the provisions of this Article.

Where, over a given year n, the actual number of service units deviates from the forecast included in the performance plan for that year n by no more than 2 %, the resulting additional revenue or the resulting revenue loss shall be borne in full by the air navigation service provider or providers concerned.

Where, over a given year n, the actual number of service units exceeds the service unit forecast included in the performance plan for that year n by more than 2 %, 70 % of the resulting additional revenue obtained by the air navigation service provider or providers concerned in excess of 2 % of the difference between the actual service units and that forecast shall be passed on to airspace users through adjustments of the unit rates in year n+2.

Where, over a given year n, the actual number of service units falls below the service unit forecast included in the performance plan for that year n by more than 2 %, 70 % of the resulting revenue loss incurred by the air navigation service provider or providers concerned in excess of 2 % of the difference between the actual service units and that forecast shall be recovered from airspace users, through adjustments of the unit rates in year n+2.

Where, over a given year n, the actual number of service units is lower than 90 % of the service unit forecast included in the performance plan for that year n, the amount of the revenue loss incurred by the air navigation service provider or providers concerned in excess of 10 % of the difference between the actual service units and that forecast shall be recovered in full, from airspace users, through adjustments of the unit rates in year n+2.

Where, over a given year n, the actual number of service units exceeds 110 % of the service unit forecast included in the performance plan for that year n, the additional revenue obtained by the air navigation service provider or providers concerned in excess of 10 % of the difference between the actual service units and that forecast shall be passed on in full, to airspace users, through adjustments of the unit rates in year n+2.

National supervisory authorities may adapt the values of the parameters of the traffic risk sharing mechanism laid out in paragraphs 2 and 3. When adapting those values, the national supervisory authorities shall:

(a) consult on the intended values the airspace users' representatives and air navigation service providers concerned;

(b) ensure that the resulting risk exposure of the air navigation service providers is not lower than the maximum revenue at risk under the mechanism laid out in paragraphs 2 and 3;

(c) consider the variation of costs of capacity provision by the air navigation service provider concerned due to variation in traffic.

The following determined costs shall not be subject to the provisions of paragraphs 2 to 5:

(a) the determined costs established in accordance with the third subparagraph of Article 22(1);

(b) the determined costs for meteorological services.

Member States may exempt from the application of paragraphs 2 to 5 the determined costs of providers of air navigation services which have received permission to provide air navigation services without certification, in accordance with Article 7(5) of Regulation (EC) No 550/2004.

In respect of the determined costs referred to in paragraph 6 and, if applicable, in paragraph 7, any additional revenue in year n due to differences between actual service units and the service unit forecast included in the performance plan for that year shall be passed on to airspace users, and any revenue loss shall be recovered from airspace users, through an adjustment of the unit rate in year n+2.

The adjustments to the unit rates referred to in points (b), (c), (d), (e), (f), (g), (h), (i), (j), (k) and (l) of Article 25(2) shall not be subject to the provisions of paragraphs 2 to 5. In respect of the adjustments referred to in points (b), (c), (d), (e), (f), (g), (i), (j) and (k) of Article 25(2), any additional revenue in year n due to differences between actual service units and the service unit forecast included in the performance plan for that year shall be passed on to airspace users, and any revenue loss shall be recovered from airspace users through an adjustment of the unit rate in year n+2.

In respect of the incentive schemes referred to in Article 11(2), a cost risk sharing mechanism shall be applied. Under that mechanism, differences between determined costs included in the performance plan and actual costs shall be shared between air navigation service providers and airspace users, in accordance with the provisions of this Article.

The differences referred to in paragraph 1 shall be shared as follows:

(a) where, over the whole reference period, actual costs fall below the determined costs, the air navigation service provider or the Member State concerned shall retain in full the resulting difference;

(b) where, over the whole reference period, actual costs exceed the determined costs, the air navigation service provider or Member State concerned shall cover in full the resulting difference.

Paragraph 2 does not apply if the differences between determined costs and actual costs result from at least one of the following changes:

(a) unforeseen changes in costs of new and existing investments;

(b) unforeseen changes in costs referred to in the third subparagraph of Article 22(1);

(c) unforeseen and significant changes in pension costs established in accordance with Article 22(4) resulting from unforeseeable changes in national pensions law, pensions accounting law or unforeseeable changes in financial market conditions, on the condition that such changes in pension costs are outside the control of the air navigation service provider and, in the case of cost increases, that the air navigation service provider has taken reasonable measures to manage cost increases during the reference period;

(d) unforeseen and significant changes in costs resulting from unforeseeable changes in interest rates on loans that finance costs arising from the provision of air navigation services, on the condition that such changes in costs are outside the control of the air navigation service provider and, in the case of cost increases, that the air navigation service provider has taken reasonable measures to manage cost increases during the reference period;

(e) unforeseen and significant changes in costs resulting from unforeseeable changes in national taxation law or other unforeseeable new cost items not covered in the performance plan but required by law.

The determined costs relating to the costs referred to in this paragraph shall be identified and categorised in the performance plan, in accordance with point 3.3(h) of Annex II.

The differences between determined and actual costs referred to in this paragraph shall be identified and explained annually in accordance with Annex VII and Annex IX.

In respect of the unforeseen changes in costs referred to in point (a) of paragraph 3, the differences between determined costs and actual costs shall be shared as follows:

(a) where, over a calendar year or over the whole reference period, actual costs fall below the determined costs, the air navigation service provider or the Member State concerned shall reimburse the resulting difference to airspace users, through a reduction of the unit rate in year n+2 or in the following reference period, unless, based on a detailed justification of the air navigation service provider, the national supervisory authority decides, after consultation with airspace users' representatives, that the air navigation service provider shall not reimburse a part of the resulting difference;

(b) where, over a calendar year or over the whole reference period, actual costs exceed the determined costs by not more than 5 %, Member States may decide that the resulting difference is recovered from airspace users by the air navigation service provider or the Member State concerned, through an increase of the unit rate in year n+2 or in the following reference period, subject to the approval by the national supervisory authority of a detailed justification provided by the air navigation service provider in particular as regards the need to increase capacity and after consultation with airspace users' representatives.

Where, during the reference period, air navigation service providers intend to add, cancel or replace major investments with respect to information on major investments identified in the performance plan in accordance with point 2.2(b) of Annex II, these changes shall be approved by the national supervisory authority, after consultation of airspace users' representatives.

In respect of the unforeseen changes in costs referred to in point (b) of paragraph 3, the differences between determined costs and actual costs shall be shared as follows:

(a) where, over a calendar year, actual costs fall below the determined costs established for that calendar year, Member States shall reimburse the resulting difference to airspace users through a reduction of the unit rate in year n+2;

(b) where, over a calendar year, actual costs exceed the determined costs established for that calendar year, Member States shall recover the resulting difference from airspace users through an increase of the unit rate in year n+2.

In respect of the unforeseen changes in costs referred to in points (c), (d) and (e) of paragraph 3, the differences between determined costs and actual costs shall be shared as follows:

(a) where, over a calendar year or over the whole reference period, actual costs fall below the determined costs, the air navigation service provider or the Member State concerned shall reimburse the resulting difference to airspace users through a reduction of the unit rate in year n+2, in the following reference period or in the following two reference periods if the amounts to be recovered impact the unit rate in a disproportionate manner;

(b) where, over a calendar year or over the whole reference period, actual costs exceed the determined costs, Member States may decide that the resulting difference is recovered from airspace users by the air navigation service provider or the Member State concerned, through an increase of the unit rate in year n+2, in the following reference period or in the following two reference periods if the amounts to be recovered impact the unit rate in a disproportionate manner.

National supervisory authorities shall verify annually whether air navigation service providers apply correctly the provisions of this Article. National supervisory authorities shall draw up a report by 1 September of year n+1 on the changes in costs referred to in paragraph 3 which occurred in year n. The report shall be subject to consultation of airspace users' representatives..

National supervisory authorities shall also include in the report which is due by 1 September of the year following the final year of the reference period the balance over the whole reference period in respect of the unforeseen changes in the costs referred to in points (a), (c), (d) and (e) of paragraph 3.

Member States shall set a unit rate for each charging zone on an annual basis in accordance with Article 25. Without prejudice to paragraph 3, unit rates shall not be modified in the course of a year.

Member States shall set a unit rate for year n for each charging zone in line with the following requirements:

(a) national supervisory authorities shall submit, on behalf of their respective Member State, the calculated unit rate to the Commission and to the CRCO of Eurocontrol by 1 June of year n-1. This submission shall include the reporting tables and additional information set out in Annex VII and Annex IX;

(b) before 1 November of year n-1, if needed, national supervisory authorities shall update the calculated unit rate referred to in point (a), following consultation with airspace users. They shall submit this calculated updated unit rate, on behalf of their respective Member State, to the Commission and the CRCO of Eurocontrol, at the latest by 1 November of year n-1;

(c) Member States shall set the unit rate for year n at the latest by 20 December of year n-1 and inform the Commission and the CRCO of Eurocontrol of that rate.

The Commission shall verify that the unit rates referred to in paragraph 2 are calculated in compliance with the requirements set out in Article 25(2).

Where the Commission finds that a unit rate does not comply with the requirements set out in Article 25(2), it shall notify the Member State concerned and invite it to submit a revised unit rate.

Where the Commission finds that the revised unit rate are calculated in compliance with the requirements set out in Article 25(2), it shall notify the Member State concerned accordingly.

Where, as a consequence of the time needed to complete the procedure referred to in paragraph 3, a unit rate for year n is revised after the start of the year to which it relates and such revision causes a difference in revenues, the unit rate shall be adjusted as follows:

(a) a first adjustment of the unit rate in the year following the revision of the unit rate, and

(b) a final adjustment of the unit rate two years after that year.

If Member States have not adopted a performance plan before the start of the reference period, or where the performance plan is revised in accordance with Article 18 during the reference period, the unit rates shall, where necessary, be recalculated and applied as soon as possible on the basis of the adopted performance plan or adopted revised performance plan.

Where a performance plan is adopted after the start of the reference period, any difference in revenue due to the application of the unit rate or unit rates calculated on the basis of the draft performance plan, instead of the unit rate or unit rates calculated on the basis of the adopted performance plan, shall result in a first adjustment of the unit rate in the year following the adoption of the performance plan and a final adjustment of the unit rate two years after that year. The provisions of Articles 27 and 28 shall be applied on the basis of the adopted performance plan and shall apply retroactively as from the first day of the reference period.

Where a performance plan is revised during the reference period in accordance with Article 18, any difference in revenue due to the application of the unit rate or unit rates calculated on the basis of the adopted performance plan, instead of the unit rate or unit rates calculated on the basis of the adopted revised performance plan, shall result in a first adjustment of the unit rate in the year following the adoption of the revised performance plan and a final adjustment of the unit rate two years after that year. The provisions of Articles 27 and 28 shall be applied on the basis of the adopted revised performance plan and shall apply retroactively as from the first day of the year to which the revised performance plan applies.

By derogation from Article 25(2), Member States may decide to set the unit rate referred to in paragraph 1 at a level lower than the unit rate calculated in accordance with Article 25(2). In that case, they shall include that lower unit rate in the reporting tables on unit rates calculation in accordance with the template of Table 2 of Annex IX. The resulting difference in revenues shall not be recovered from airspace users.

Member States shall, by 1 August of each year, in a coordinated manner, consult the air navigation service providers, airspace users' representatives, and, where relevant, airport operators and airport coordinators on essential elements relating to the implementation of this Regulation as set out in point 2 of Annex XII. This consultation may be conducted together with the consultation referred to in Article 24(3).

Member States shall provide the reporting tables and the information required in Annex IX to the consulted parties at least three weeks before the consultation.

Member States shall provide the information referred to in the second subparagraph of paragraph 1 to the Commission on the same day when it is provided to the consulted parties. Member States shall inform the Commission about the outcome of the consultation.

The en route charge for a given flight in a given en route charging zone shall be equal to the product of the unit rate established for that en route charging zone and the en route service units for that flight.

The terminal charge for a given flight in a given terminal charging zone shall be equal to the product of the unit rate established for that terminal charging zone and the terminal service units for that flight.

For the purpose of calculating the terminal charge, the approach and departure of a flight shall count as a single flight. The unit to be counted shall be either the arriving or the departing flight.

Member States shall exempt the following flights from en route charges:

(a) flights performed by aircraft with a maximum authorised take-off weight which is less than two metric tons;

(b) mixed VFR/IFR flights in the charging zones where they are performed exclusively under VFR and where an en route charge is not levied for VFR flights;

(c) flights performed exclusively for the purpose of transport, on official mission, of reigning Monarchs and their immediate family, heads of state, heads of government and government ministers, where it is substantiated by the appropriate status indicator or remark on the flight plan that the flight is performed exclusively for that purpose;

(d) search and rescue flights authorised by the appropriate competent body.

Member States may exempt the following flights from en route charges:

(a) military flights performed by aircraft of a Member State or any third country;

(b) training flights performed solely within the airspace of the Member State concerned and exclusively for the purpose of obtaining a licence, or a rating in the case of cockpit flight crew, where it is substantiated by an appropriate remark on the flight plan that the flight is performed exclusively for that purpose;

(c) flights performed exclusively for the purpose of checking or testing equipment used or intended to be used as ground aids to air navigation, excluding positioning flights by the aircraft concerned;

(d) flights terminating at the airport from which the aircraft has taken off and during which no intermediate landing has been made;

(e) VFR flights;

(f) humanitarian flights authorised by the appropriate competent body;

(g) customs and police flights.

Member States may exempt from terminal charges the flights referred to in paragraphs 3 and 4.

Member States shall cover the costs for the services that air navigation service providers have provided to flights exempted from en route charges or terminal charges in accordance with paragraph 3, 4 or 5.

Member States may, on a non-discriminatory and transparent basis, modulate air navigation charges for airspace users to:

(a) optimise the use of air navigation services;

(b) reduce the environmental impact of flying;

(c) reduce the level of congestion of the network in a specific area or on a specific route at specific times.

(d) accelerate the deployment of SESAR ATM capabilities in anticipation of the time period set out in the common projects referred to in Article 15a(3) of Regulation (EC) No 550/2004, in particular with a view to giving incentives to equip aircraft with systems included in those common projects.

Member States shall ensure that modulation of charges in respect of points (a) to (c) of this paragraph does not result in any overall change in annual revenue for the air navigation service provider compared to the situation where charges would not have been modulated. Over- or under recoveries shall result in an adjustment of the unit rate in year n+2.

Modulation of air navigation charges shall be applied in respect of the en route charge or the terminal charge, or both.

Before the application of the modulation of charges, Member States shall consult airspace users' representatives and air navigation service providers concerned on such intended modulation.

National supervisory authorities shall monitor the proper implementation of the modulation of air navigation charges by air navigation service providers and report in accordance with Article 37(1).

Member States may collect charges through a single charge per flight. Where charges are billed and collected on a regional basis, the billing currency may be the euro and an administrative unit rate for billing and collection costs may be added to the unit rate concerned.

Member States shall ensure that the amounts collected on their behalf are used to finance the determined costs in accordance with the provisions of this Regulation.

Airspace users shall promptly and fully pay all air navigation charges incurred in accordance with this Regulation.

Member States shall ensure that effective, and proportionate enforcement measures for the collection of air navigation charges are applied where necessary. Those measures may include denial of services, detention of aircraft or other enforcement measures in accordance with the law of the Member State concerned.

Subject to the conditions set out in paragraph 2, Member States may decide to establish and apply a simplified charging scheme for the duration of an entire reference period in respect of:

(a) one or more en route and one or more terminal charging zones;

(b) one or more air navigation service providers providing services in the charging zone or zones referred to in point (a).

Member States may decide to establish and apply a simplified charging scheme referred to in paragraph 1 only if all of the following conditions are met:

(a) a Commission decision adopted pursuant to Article 14(2), Article 15(2) or Article 15(4) confirms that the performance targets set by the Member State in the draft performance plan referred to in Article 12 are consistent with the Union-wide performance targets;

(b) the performance targets in the key performance areas of safety, capacity and environment have been met in the three years preceding the adoption of the draft performance plan referred to in Article 12;

(c) the performance plan includes an incentive scheme on capacity targets as required in Article 11;

(d) the air navigation service providers concerned and the airspace users concerned have been consulted on the intended decision and airspace users representing at least 65 % of the IFR flights operated in the airspace where the Member State or Members States concerned are responsible for the provision of air navigation services agree with the intended decision.

If Member States decide to establish and apply a simplified charging scheme pursuant to paragraph 2, they shall not apply:

(a) the traffic risk sharing mechanism referred to in Article 11(2) and Article 27. By not applying the traffic risk sharing mechanism, the traffic risk is therefore borne in full by the air navigation service provider;

(b) the provisions of Article 28(4) to (6) related to the cost risk sharing mechanism;

(c) the over or under recoveries resulting from the modulation of air navigation charges pursuant to Article 32.

Any carry-over from the years preceding the reference period to which the simplified charging scheme is applied, shall still be taken into account in the calculation of unit rates.

If Member States decide to establish and apply a simplified charging scheme pursuant to paragraph 2, they shall specify and substantiate their decision in the performance plan, in accordance with point 1.7 of Annex II.

Subject to the provisions of this Article, Member States may decide, either before or during a reference period, that the provision of some or all of the terminal air navigation services, CNS, MET, AIS services or air traffic management (ATM) data services provided in their charging zones established in accordance with Article 21 is subject to market conditions.

Where a Member State or Member States decide to apply paragraph 1, for the upcoming reference period or, as the case may be, for the remaining duration of the reference period and in respect of the services concerned they shall not:

(a) apply cost-efficiency targets, including the setting of determined costs, for the key performance indicators referred to in point 4.1 of Section 2 of Annex I;

(b) apply traffic risk sharing and cost sharing mechanisms in accordance with Articles 27 and 28;

(c) set financial incentives in the key performance areas of capacity and environment in accordance with Article 11;

(d) calculate terminal charges in accordance with Article 31(2);

(e) set terminal unit rates in accordance with Article 29;

(f) be subject to the consultation requirements specified in Article 24(3).

Points (d) to (f) apply only to terminal air navigation services.

Where, during a reference period, a Member State decides to apply paragraph 1, it shall also revise its performance plan in accordance with Article 18(1) in respect of the services concerned.

A Member State shall decide to apply paragraph 1 only after having completed all of the following steps:

(a) its national supervisory authority has found, on the basis of a detailed assessment in accordance with the conditions laid down in Annex X, that the provision of the services concerned is subject to market conditions;

(b) it has consulted the airspace users' representatives concerned on the intended decision and on that assessment, and has taken account of their comments where appropriate;

(c) it has made its intended decision and that assessment publicly available;

(d) it has submitted its intended decision and that assessment to the Commission and received the agreement of the Commission.

As regards point (d), the Member State shall submit the assessment no later than 12 months before the start of a reference period or, in the event of an assessment during the reference period, without undue delay upon having completed the assessment. The Commission shall notify the Member State concerned whether it agrees that the assessment has been carried out in accordance with the conditions laid down in Annex X. The Commission shall do so without undue delay. Where necessary, the Commission shall request additional information from the Member State concerned, which that Member State shall provide without undue delay.

If a Member State decides to apply paragraph 1, its national supervisory authority shall assess regularly whether the conditions laid down in Annex X continue to be met.

If the national supervisory authority finds that those conditions are no longer met, the Member State shall, without undue delay, revoke its decision, after having completed the steps set out in points (b) to (d) of paragraph 3.

Upon that revocation, the Member State shall, for the upcoming reference period or, as the case may be, for the remaining duration of the reference period, not apply the exemptions listed in the first subparagraph of paragraph 2 in respect of the services concerned. If the revocation occurs during the reference period, the Member State concerned shall also revise its performance plan in accordance with Article 18(1).

If the services subject to the application of paragraph 1 are provided in a common charging zone set up in accordance with Article 21(4), the Member States concerned may decide to establish that the provision of some or all of those services are subject to market conditions only jointly. In that case, they shall jointly ensure that the requirements of this Article are respected.

If a Member State decides to apply paragraph 1, it shall submit to the Commission the information specified in Annex XI in the first year of each reference period. The Commission shall not make that information publicly available.

For the purpose of monitoring in accordance with Article 37, national supervisory authorities, air navigation service providers, airport operators, airport coordinators, airspace users and the Network Manager shall provide to the Commission the data referred to in Annex VI in accordance with the specific requirements applicable to each party set out in that Annex. The data shall be provided free of charge in an electronic format.

With respect to airspace users, this Article shall only apply to those users which operate more than 35000 flights per year in European airspace, calculated as the average over the previous three years.

Where the parties referred to in paragraph 1 already provided some or all of that data to Eurocontrol or the European Union Aviation Safety Agency, they shall not be required to provide the data concerned to the Commission, provided that they inform the Commission about data they already provided, when they provided it and whether they provided it to Eurocontrol or to the European Union Aviation Safety Agency.

The parties referred to in paragraph 1 shall each take the necessary measures to ensure the quality, validation and timely transmission of the data that they are to provide in accordance with paragraph 1. They shall, upon request by the Commission, provide information on their quality checks and validation processes in respect of that data.

The national supervisory authorities shall monitor the performance of air navigation services provided in the airspace under their responsibility, with a view to assessing whether the performance targets contained in the performance plans are met.

If a national supervisory authority finds that those targets are not met, or risk not being met, it shall immediately inform the Commission thereof. Without undue delay, the Member State or the national supervisory authority concerned shall, in order to rectify the situation and achieve the targets set in the performance plan, apply the appropriate measures they have defined, taking into consideration the remedial measures referred to in Article 10(2) of Implementing Regulation (EU) 2019/123. They shall communicate those appropriate measures to the Commission without undue delay.

Not later than 1 June of each year, the national supervisory authorities shall report to the Commission on the results of the monitoring referred to in the first subparagraph in the preceding year.

The Commission shall monitor the performance of the network functions and assess whether the performance targets contained in the Network Performance Plan are met.

If the Commission finds that the performance targets contained in the Network Performance Plan are not met or risk not being met, it shall request the Network Manager to define appropriate measures in order to rectify the situation and achieve those targets. The Network Manager shall communicate those measures to the Commission without undue delay.

On the basis of the reports referred to in the last subparagraph of paragraph 1, its own monitoring referred to in paragraph 2, and the analysis of data received in accordance with Article 36(1), the Commission shall monitor the performance of the provision of air navigation services and network functions and carry out regular assessments of the achievement of the performance targets. The Commission shall inform Member States of its monitoring activities at least once a year.
