I am a bit irritated that a car navigation app MAPS.ME using OSM data (e.g. France, Gemany, Belgium…) is displaying every tiniest leisure airfield as if it were an international airport.
I wrote to the design team who explained to me that OSM database do not provide the information whether is is a big relevant airport or just a green acre belonging to a group of hobbyists.
Unfortunately no. At https://wiki.openstreetmap.org/wiki/Key:aerodrome:type take a closer look at the last column “Count”. Only 11+222+33=266 elements in the database have this tag (and this might include duplicates). I expect there are more international airports in the world.
