| Official Journal of the European Union | EN L series ---|---|--- * * * | 2024/3128 | 17.12.2024 ---|---|--- COMMISSION IMPLEMENTING REGULATION (EU) 2024/3128 of 16 December 2024 amending Implementing Regulation (EU) 2019/317 as regards new and revised monitoring indicators for the performance and charging scheme in the single European sky (Text with EEA relevance) 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) (1), and in particular Article 11(6) thereof, Whereas: (1) | The performance and charging scheme in the single European sky set up in accordance with Commission Implementing Regulation (EU) 2019/317 (2) contains regulatory instruments to set targets and to monitor and report on the performance of air navigation services and network functions in the key performance areas of safety, environment, capacity, and cost efficiency. In addition to key performance indicators on which targets are set, the scheme includes indicators for monitoring the performance in all four key performance areas for both en route and terminal air navigation services, as well as network functions, to improve the overall performance of the network. ---|--- (2) | New developments in measurement of performance and availability of data have allowed to improve the existing indicators and to add new indicators for monitoring the performance of air navigation services and network functions. The information which the new and improved indicators can provide is crucial for the development of the performance and charging scheme in future reference periods. ---|--- (3) | The work of the performance review body referred to in Article 11(2) of Regulation (EC) No 549/2004 has shown that it is necessary to explore ways to improve the environmental performance of the network to contribute to the implementation of the requirements of the European Green Deal (3). Currently, only certain elements of the flight trajectory are covered by the indicators. Therefore, new indicators are necessary in order to measure more precisely the environmental performance of certain elements such as continuous climb operation, taxi-in time, and vertical flight efficiency. In addition, to improve environmental and overall performance, indicators for monitoring in the key performance area of capacity capturing throughput should be included. ---|--- (4) | The introduction of new or amended indicators should not increase the reporting burden as such indicators should be calculated largely on the basis of data already available to Eurocontrol. ---|--- (5) | Due to the number of amendments that need to be made in Annex I to Implementing Regulation (EU) 2019/317 and in order to improve its structural and linguistic coherence, that Annex should be replaced entirely. ---|--- (6) | This Regulation should apply in the fourth reference period and in the subsequent reference periods. ---|--- (7) | The measures provided for in this Regulation are in accordance with the opinion of the Single Sky Committee, ---|--- HAS ADOPTED THIS REGULATION: Article 1 Implementing Regulation (EU) 2019/317 is amended as follows: | Annex I is replaced by the text in the Annex to this Regulation; ---|--- | In Annex VI, point 3(a), ‘2018’ is replaced by ‘2019’. ---|--- Article 2 This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. It shall apply from 1 January 2025. This Regulation shall be binding in its entirety and directly applicable in all Member States. Done at Brussels, 16 December 2024.
