The single European sky initiative aims to increase the efficiency of air traffic management (ATM) and air navigation services by reducing the fragmentation of European airspace. By its nature, this ongoing initiative is pan-European and open to neighbouring countries.

Parliament has always endeavoured to remove obstacles to the implementation of the single European sky by adopting a pragmatic approach. In this connection, it has insisted strongly and successfully on the need for close cooperation between the civil and military sectors, in the context of flexible use of airspace, even when the Member States were still reluctant to address the issue.
