Article 2
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.
