eAIP in France list two services on AD-2 (aerodromes) for which I have no clue what they stand for. They are not known to AIXM neither.

Any idea what these services are? Thanks a bunch!


When in doubt, check GEN 2.2 for a list of abbreviations.

  • CEV
    Centre d’essai en vol
    Flight test centre
  • SRE
    Elément radar de surveillance du système radar d’approche de précision
    Surveillance radar element of precision approach radar system

CEV and SRE are ATC services restricted to defense aviation. That's why you don't have information in the AIP. The procedures are only available in the DirCAM AIP (CAM is for Circulation Aérienne Militaire, military aircraft).


This service is provided to Direction Générale de l'Armement (DGA), the French Defense Procurement Agency, for its flight tests. CEV comes from the previous name of the DGA infrastructure: "Centre d'Essais en Vol".


ATC service used for approach to military bases using a Search Radar Equipment (SRE) renamed Surveillance Radar Element as noted by ymb in his answer

A SRE is a long range panoramic radar, part of a Ground Controlled Approach (GCA). The GCA is composed of two segments:

  • One used before the actual approach, using the SRE to determine the position of the aircraft and then guide it to the Initial Approach Fix where the PAR radar takes over.

  • The Precision Approach Radar (PAR) segment where the PAR is used to guide the aircraft to the runway threshold.

Difference between a SRE radar (left) and a PAR radar (right):

A PAR procedure at Avord base looks like this:

The PAR approach above for example requires a Tacan transponder in the aircraft, something civil aircraft don't have (they have only the DME portion).

  • $\begingroup$ That's interesting that France does not provide PAR to civilian aircraft at all -- my understanding is that PAR service at US military bases is available to civil aircraft authorized to use the base (which can be "all of them" at joint civ/mil facilities such as KNYL) $\endgroup$ – UnrecognizedFallingObject Feb 15 at 4:22
  • $\begingroup$ @UnrecognizedFallingObject: Military air bases are for "CAM" only, not open to "CAG". Only civilian allowed are CEV flights. Except emergencies of course, which happen from time to time (Space Shuttle was allowed to land at Istres, but it was a specific agreement with US personnel on the base). There are no jointly managed airspaces, only military representatives at civil ATC enroute centers to facilitate CAM in CAG airspaces. $\endgroup$ – mins Feb 15 at 9:11
