Is a farm strip an aerodrome? Surely an aerodrome would have an ICAO code assigned to it.
ANO definition:
[Aerodrome] Means any area of land or water designed, equipped, set apart or commonly used for affording facilities for the landing and departure of aircraft and includes any area or space, whether on the ground, on the roof of a building or elsewhere, which is designed, equipped or set apart for affording facilities for the landing and departure of aircraft capable of descending or climbing vertically.
