EUROCONTROL’s Maastricht Upper Area Control Centre (MUAC) and DFS Deutsche Flugsicherung GmbH have just signed a collaboration agreement which encompasses a range of bilateral initiatives in the areas of airspace optimisation, technical cooperation and harmonisation of procedures. This collaboration agreement, which is fully in line with the objectives of the Single European Sky, will boost the implementation of a uniform European air traffic management system in a part of the continent that hosts some of Europe’s largest airports.
