(4) Commission Implementing Decision (EU) 2024/1688 of 12 June 2024 setting Union-wide performance targets for the air traffic management network for the fourth reference period from 1 January 2025 to 31 December 2029 (OJ L, 2024/1688, 17.6.2024, ELI: http://data.europa.eu/eli/dec_impl/2024/1688/oj). ELI: http://data.europa.eu/eli/dec/2025/1052/oj 1/7EN OJ L, 28.5.2025 (6) In accordance with Article 14(1) of Implementing Regulation (EU) 2019/317, the Commission has assessed the consistency of the local performance targets included in the draft performance plan on the basis of the criteria laid down in point 1 of Annex IV to that Implementing Regulation, and taking account of local circumstances where relevant. (7) The Commission has complemented its assessment of the draft performance plan with a review of the elements set out in point 2 of Annex IV to that Implementing Regulation. In respect of point 2.1(d)(vii) of Annex IV to Implementing Regulation (EU) 2019/317, the Commission notes that it has not conducted, as part of that review, a detailed analysis of the methodology used by Slovenia for the allocation of costs between en route and terminal services in RP4. Therefore, the Commission has not drawn any conclusions, at this stage, in respect of the compliance of that cost allocation methodology with points (e) and (f) of Article 15(2) Regulation (EC) No 550/2004 of the European Parliament and of the Council(5) and Article 22(5) of Implementing Regulation (EU) 2019/317. COMMISSION ASSESSMENT Assessment of the safety targets (8) As regards the key performance area of safety, the consistency of the targets included in the draft performance plan has been assessed in accordance with point 1.1 of Annex IV to Implementing Regulation (EU) 2019/317. (9) The performance targets in the key performance area of safety proposed by Slovenia in respect of the effectiveness of safety management, broken down per safety management objective and expressed as a level of implementation, are as follows: Targets on the effectiveness of safety management, expressed as a level of implementation, Slovenia ranging from EASA level A to D Air navigation Safety management 2025 2026 2027 2028 2029 service provider objective Safety policy and C C C C C objectives Safety risk management D D D D D Slovenia Control Safety assurance C C C C C Safety promotion C C C C C Safety culture C C C C C (10) The Commission has found that the safety performance targets proposed by Slovenia for the air navigation service provider ‘Slovenia Control’ are equal to the Union-wide safety targets in respect of each calendar year from 2025 to 2029. (11) The Commission notes that the draft performance plan sets out measures for Slovenia Control for the achievement of the local safety targets, such as the definition of a new operational risk baseline subject to regular reviews, the evaluation of statistical data, and the use for monitoring purposes of an alerting system enabling the detection of adverse safety trends. (5) 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 sky (the service provision Regulation) (OJ L 96, 31.3.2004, p. 10, ELI http://data.europa.eu/eli/reg/ 2004/550/oj). 2/7 ELI: http://data.europa.eu/eli/dec/2025/1052/ojEN OJ L, 28.5.2025 (12) On the basis of the findings set out in recitals (9), (10) and (11), the local safety performance targets included in the draft performance plan should be considered consistent with the Union-wide performance targets. Assessment of the environment targets (13) As regards the key performance area of environment, the consistency of the targets included in the draft performance plan regarding the average horizontal en routeflight efficiency of the actual trajectory has been assessed based on the criterion laid down in point 1.2 of Annex IV to Implementing Regulation (EU) 2019/317. Accordingly, the proposed environment targets of Slovenia have been compared to the relevant en route horizontal flight efficiency reference values set out in the European Route Network Improvement Plan (‘ERNIP’), drawn up in accordance with Annex I to Commission Implementing Regulation (EU) 2019/123(6) and available at the time of adopting the Union-wide performance targets for RP4, that is on 2 July 2024. (14) The environment performance targets proposed by Slovenia for RP4 and the corresponding national reference values from the ERNIP, expressed as the average horizontal en routeflight efficiency of the actual trajectory, are as follows: Slovenia 2025 2026 2027 2028 2029 Targets in the key performance area of environment, expressed as 1,70 % 1,67 % 1,64 % 1,61 % 1,58 % the average horizontal en routeflight efficiency of the actual trajectory Reference values 1,70 % 1,67 % 1,64 % 1,61 % 1,58 % (15) The Commission observes that the environment targets proposed by Slovenia are equal to the corresponding national reference values for each calendar year of RP4. (16) The Commission notes that Slovenia has presented in the draft performance plan measures for the achievement of the local environment targets, including the implementation of cross border free route airspace and the application of recommendations for flight efficiency improvements set out in the ERNIP. (17) On the basis of the findings set out in recitals (14), (15) and (16), the targets in the key performance area of environment included in the draft performance plan should be considered consistent with the Union-wide performance targets for RP4. Assessment of the capacity targets (18) As regards the key performance area of capacity, the consistency of the targets included in the draft performance plan regarding the average en routeair traffic flow management (‘ATFM’) delay per flight has been assessed based on the criterion laid down in point 1.3 of Annex IV to Implementing Regulation (EU) 2019/317. Accordingly, the proposed capacity targets of Slovenia have been compared to the relevant reference values set out in the Network Operations Plan drawn up in accordance with Article 9 of Commission Implementing Regulation (EU) 2019/123 and available at the time of adopting the Union-wide performance targets for RP4, that is on 2 July 2024. (19) The en routecapacity targets proposed by Slovenia for RP4, expressed in minutes of ATFM delay per flight, and the corresponding reference values from the Network Operations Plan, are as follows: (6) Commission 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, ELI: http://data.europa.eu/eli/reg_impl/2019/123/oj). ELI: http://data.europa.eu/eli/dec/2025/1052/oj 3/7EN OJ L, 28.5.2025 Slovenia 2025 2026 2027 2028 2029 Targets in the key performance area of capacity, expressed in 0,17 0,12 0,08 0,07 0,07 minutes of en routeATFM delay per flight Reference values 0,17 0,12 0,08 0,07 0,07 (20) The Commission observes that the en route capacity targets proposed by Slovenia are equal to the corresponding national reference values for each calendar year of RP4. (21) The Commission notes that Slovenia has presented, in the draft performance plan, measures for the achievement of the local en route capacity targets, including the implementation of enhanced air traffic flow and capacity management, adjustments to the traffic organisation in response to changes in regional traffic flows, the training and recruitment of additional air traffic controllers, and upgrades to the air traffic management system. (22) On the basis of the findings set out in recitals (19), (20) and (21), the targets in the key performance area of capacity included in the draft performance plan should be considered consistent with the Union-wide performance targets for RP4. Assessment of the cost-efficiency targets (23) As regards the key performance area of cost-efficiency, the consistency of the targets included in the draft performance plan regarding the determined unit cost (‘DUC’) for en route air navigation services has been assessed based on the criteria laid down in points 1.4(a), (b) and (c) of Annex IV to Implementing Regulation (EU) 2019/317. Those criteria consist of the DUC trend over RP4, the long-term DUC trend over the third reference period (‘RP3’) and RP4 (2020-2029), and the baseline value for the DUC at charging zone level compared with the average value of the charging zones where air navigation service providers have a similar operational and economic environment. (24) The en routecost-efficiency targets proposed by Slovenia for RP4, and the related baseline values, are as follows: 2019 2024 En routecharging zone of baseline baseline 2025 2026 2027 2028 2029 Slovenia value value Targets and baseline values in the key performance area of cost-efficiency, EUR EUR EUR EUR EUR EUR EUR expressed as determined unit 60,67 55,98 55,22 55,13 54,65 54,12 52,83 cost (in real terms at 2022 prices) (25) Concerning the assessment criterion set out in point 1.4(a) of Annex IV to Implementing Regulation (EU) 2019/317, the Commission observes that Slovenia’s DUC trend at charging zone level of -1,2 % over RP4 is in line to the Union- wide trend of -1,2 % over the same period. (26) Concerning the assessment criterion set out in point 1.4(b) of Annex IV to Implementing Regulation (EU) 2019/317, the Commission observes that Slovenia’s long-term DUC trend at charging zone level over RP3 and RP4 of -1,5 % outperforms the long-term Union-wide trend of -1,0 % over the same period. 4/7 ELI: http://data.europa.eu/eli/dec/2025/1052/ojEN OJ L, 28.5.2025 (27) Concerning the assessment criterion set out in point 1.4(c) of Annex IV to Implementing Regulation (EU) 2019/317, the Commission observes that Slovenia’s baseline value for the DUC of EUR 55,98 in real terms at 2022 prices (‘EUR2022’) is 55,4 % higher than the average baseline value of EUR 36,04 in EUR2022 of the relevant comparator group set out in Article 7 Implementing Decision (EU) 2024/1688. (28) It is clear that Slovenia's DUC trend for RP4 is in line with the Union-wide RP4 DUC trend whilst Slovenia’s long-term DUC trend outperforms the Union-wide long-term DUC trend. Slovenia thus demonstrates that effective cost- efficiency gains are achieved both over the medium and long term. Therefore, the Commission considers that the deviation between Slovenia’s baseline value in comparison with the relevant comparator group referred to in recital (27) does not preclude Slovenia’s consistency with the Union-wide cost-efficiency performance targets. (29) On the basis of the findings set out in recitals (24) to (28), the targets in the key performance area of cost-efficiency included in the draft performance plan should be considered consistent with the Union-wide performance targets for RP4. CONCLUSIONS (30) In the light of the foregoing, the performance targets included in the draft performance plan of Slovenia should be considered consistent with the Union-wide performance targets for RP4, HAS ADOPTED THIS DECISION: Article 1 The performance targets included in the draft performance plan submitted by Slovenia for the fourth reference period (‘RP4’), listed in the Annex to this Decision, are consistent with the Union-wide performance targets for RP4 set out in Implementing Decision (EU) 2024/1688.
