Commission Implementing Decision (EU) 2025/1039 of 16 May 2025 on the inconsistency of certain performance targets included in the draft performance plan submitted by Switzerland pursuant to Regulation (EC) No 549/2004 of the European Parliament and of the Council with the Union-wide performance targets for the fourth reference period of the Single European Sky performance and charging scheme (notified under document C(2025) 2923)

The performance targets in respect of Switzerland listed in the Annex to this Decision, which are included in the draft performance plan of the Functional Airspace Block Europe Central are inconsistent with the Union-wide performance targets for the fourth reference period set out in Commission Implementing Decision (EU) 2024/1688.

Switzerland shall revise downwards the cost-efficiency targets set for its en route charging zone, expressed as determined unit cost (DUC). When revising its cost-efficiency targets, Switzerland shall: (a) ensure that the revised cost-efficiency targets are consistent both with the Union-wide DUC trend and with the Union-wide long-term DUC trend, referred to, respectively, in point 1.4(a) and (b) of Annex IV to Implementing Regulation (EU) 2019/317; (b) reduce the level of determined costs accordingly, in particular in respect of calendar year 2029; (c) use the latest traffic forecasts, expressed in service units, in accordance with Article 10(2) of Implementing Regulation (EU) 2019/317. If Switzerland invokes in the revised draft performance plan to be submitted in accordance with Article 14(3), second subparagraph, of Implementing Regulation (EU) 2019/317 a deviation under point 1.4(d) of Annex IV to that Implementing Regulation, it shall ensure that such a deviation is substantiated with adequate information and justifications. In particular, Switzerland shall demonstrate that any measures invoked to justify a deviation from Union-wide cost-efficiency targets relate solely to additional operational resources or technical capabilities necessary to meet the capacity targets.

This Decision is addressed to the Swiss Confederation.
