EUROCONTROL's Maastricht Upper Area Control Centre (MUAC) is responsible for the airspace above FL245 within Brussels UIR, Amsterdam FIR and Hannover UIR. This includes airspace and traffic flow design due to which we contribute to the content of national Aeronautical Information Publications (AIPs) and the Route Availability Document (RAD).
If you are an aircraft operator or a computerised flight planning service provider (CFSP) and you need assistance with regard to flight planning, routeings through the MUAC airspace or RAD restrictions which contain the designator YX, contact us and we will support you by providing more information on specific issues.
