Airspace management (ASM)

ENAIRE’s experience in creating and optimising air routes has driven a saving of 3.5 Mn nautical miles in distances flown over the past three years and 38,900 tonnes of fuel. This translates into the non-emission into the atmosphere of 123,000 tonnes of CO2.

We were one of the first major air navigation service providers to implement the Free Route project which over coming years will enhance traffic flows and implement more direct flight segments right across the European Union airspace.

ENAIRE designs efficiency, service continuity and airspace optimisation plans that define structural improvement measures. As an air navigation service provider it also manages civil-military coordination to optimise airspace use in accordance with the FUA (Flexible Use of Airspace) concept so that all users, both civil and military, find their operational needs met.

We plan and manage all Spanish airspace structures and coordinate their use for purposes other than commercial transport.

ENAIRE provides its airspace management (ASM) services by coordinating air navigation activities, both military and civil, which, without being commercial air transport, are conducted in our airspace, such as:

  • Major military exercises, e.g., NATO manoeuvres.
  • Aerial works (photographic flights, power line checks, covering sports activities like bike races and aerial filming).
  • Sports activities (hot-air ballooning events, parachute drops, air festivals, etc.).
  • Citizen and air safety activities at public events with crowds of people, such as Formula 1 and Moto GP races.
  • Any other activity for airspace use, including drones (RPAs) that require NOTAM communication.

A NOTAM contains information concerning the establishment, conditions or change in any aeronautical facility, service or procedure, the timely knowledge of which is essential to airspace users, as well as weather alerts and warnings regarding reserved zones that cannot be penetrated by aircraft.

NOTAMS are published by ENAIRE, the sole aeronautical information service (AIS) provider in Spain authorised by the Directorate-General for Civil Aviation (DGAC), in compliance with the international regulations of the International Civil Aviation Organization (ICAO).

If you require the coordination of any of these activities, please contact us at
