(2)Belgium, Germany, France, Luxembourg and the Netherlands, as regards Functional Airspace Block Europe Central (‘FABEC’), submitted such a plan to the Commission. Pursuant to Commission Implementing Decision (EU) 2015/347note, those Member States revised the plan and the targets included therein. However, by means of Implementing Decision (EU) 2017/259note, the Commission established that the revised performance targets concerning the key performance areas of capacity for FABEC as a whole and cost-efficiency for France, Germany and the Netherlands, as well as the appropriate measures included in the revised plan, were still not adequate and that those Member States are to take certain corrective measures leading to further revised performance targets so as to address inconsistencies with the Union-wide targets.
