airstrips
In addition to altiports, France allows mountain airstrips (altisurfaces) to be created. An altisurface is a mountain landing strip for aeroplanes that is not an altiport. These are sites in the mountains that may be used by certain aircraft for aerial work, on-demand transport or non-commercial air operations. They are approved by prefectoral order and restricted to pilots with appropriate training and ratings flying suitable aircraft.
Unlike an altiport, an altisurface is not an aerodrome in the legal sense. It has no ICAO or IATA code, but is listed instead by what Americans call a LID (location identifier), in the form LFddnn, where dd is the number of the département where the altisurface lies and nn its rank in the order of approvals for that département.
Example: the Escoulin mountain airstrip (LF2624)
