Major airspace restructure delivers significant efficiency benefits in one of Europe’s busiest and most complex areas. Maastricht, the Netherlands; 20 March 2025: The EUROCONTROL Maastricht Upper Area Control Centre (MUAC), together with its partners, today announced the successful implementation of a major multifaceted airspace restructure above the Netherlands and north-west Germany. The new design, which is the result of several years of collaborative effort, will improve operational efficiency and optimise airspace usage for all users, whether civil or military, in what is one of Europe’s busiest and most complex areas. The purpose of the restructure is to prepare for future air traffic demand and to accommodate the evolving requirements of both military and civil airspace users. A key element of the new design is a new dual-route structure along re-shaped military training area boundaries which separates opposite traffic flows. This allows for more efficient continuous climb and descent flight profiles, even when the training areas are in use, offering a reduction in fuel burn. (....)
