In accordance with Regulation (EC) No 549/2004, as incorporated into the Agreement, the Member States and Switzerland are to adopt national or functional airspace block (‘FAB’) plans, including binding national targets or targets at the level of FABs, ensuring consistency with the Union-wide performance targets. Regulation (EC) No 549/2004 also provides that the Commission is to assess the consistency of those targets on the basis of the assessment criteria referred to in point (d) of Article 11(6) of that Regulation. Detailed rules in this regard have been set out in Implementing Regulation (EU) No 390/2013.

On 30 January 2017 Switzerland submitted a further revised plan including corrective measures leading to further revised performance targets. Those revised targets and corrective measures were subsequently assessed by the Commission.

Concerning the key performance area of capacity, the consistency of those targets for en route air traffic flow management (ATFM) delay has been assessed, in accordance with the principle laid down in point 4 of Annex IV to Implementing Regulation (EU) No 390/2013, by using the respective FAB reference values for capacity that, when applied, ensure at Union level that the Union-wide performance target is met, calculated by the Network Manager and set out in the Network Operations Plan (2014-2018/2019) in its most recent version. That assessment has demonstrated that those targets are consistent with the relevant Union-wide performance targets.

Concerning the key performance area of cost-efficiency, those targets expressed in en route determined unit costs, have been assessed, in accordance with the principles laid down in point 5, in conjunction with point 1, of Annex IV to Implementing Regulation (EU) No 390/2013, by taking account of the trend of en route determined unit costs over the second reference period and the combined period of the first and the second reference period (2012-2019), the number of service units (traffic forecast) and the level of en route determined unit costs in comparison to Member States having a similar operational and economic environment. That assessment has demonstrated that those targets are consistent with the relevant Union-wide performance targets.

Therefore, the corrective measures taken by Switzerland, as regards FABEC, are consistent with Implementing Decision (EU) 2017/258 and the targets concerning the key performance areas of capacity and cost-efficiency included in the revised performance plan submitted by Switzerland are consistent with the Union-wide performance targets in those areas for the second reference period (2015-2019). It is appropriate, for reasons of clarity and legal certainty, to establish that finding by means of this Decision and notify Switzerland thereof.

The Commission has consulted Switzerland on this Decision, in accordance with Article 19(2) of the Agreement.

The measures provided for in this Decision are in accordance with the opinion of the Single Sky Committee,
