The words and values used in OSM do not necessarily have the same meaning as the local definitions.

In fact there should be a comparison between the two before use of the data in OSM.

An 'airstrip' that has no facilities I would map in OSM as a runway without any other aeroway features.
So not aeroway=airport.
