Airspaces

The ICAO / EASA framework provides 7 airspaces definition common throughout ICAO / EASA countries.

You may find here a definition of all airspaces and the services provided in each one of them:

Important to know for Switzerland !
  • G Airspace is a layer of 2000ft AGL.
  • C Airspace starts at FL100 in the mainland and FL 130 in the alpine region.
  • Military ON, then the C Airspace starts at FL130.
  • Military OFF, then  the C Airspace starts at FL150.

(1) : General speed limit is 250kts IAS enforced below FL100 (10’000ft).

(2) : Separation as far as practical.

(3) : Service to participating IFR traffic only (non participating IFR to file FP and maintain 2-way comms).

(4) : Radar information / advice may be provided to augment FIS in CAS.

(5) : Not used in Switzerland.
