The Airspace Management process enables the NEFAB states to effectively share the airspace availability between civil and military users.
Airspace Management process
Approved Agencies, e.g. military, will request the reservation of areas one day before the planned activity. These reservations, once accepted, are promulgated in the Airspace Use Plan. The AUP describes the next day scheduled activation of areas including vertical extensions.
When a user is trying to file a route too close to a planned active area the flight plan will be rejected by the EUROCONTROL Network Manager. Aircraft operators shall then re-file with additional waypoint(s) to avoid the area.
If the reserved area becomes available sooner than planned, an Updated Use Plan (UUP) is issued and flight plans through the de-activated area will be accepted.
