Once again, it's a set of categories that doesn't quite fit the US. To the FAA, an 'airport' is pretty much defined as the place where you plan to land. Whether landing there is lawful is a matter of state law, and some states, such as Alaska, place very few restrictions on where a pilot may land (with the permission of the landowner, of course). FAA does require notification (not permission) if a landowner constructs improvements to make an airport and conducts more than ten operations in a day or operates more than three days a week. That's in order to publish the locations of runways in the Airports and Facilities Directory. A bush strip, 2000 x 60 feet, in Alaska, with 4-foot-tall grass and 8-foot-tall willow in the 'runway', which is also used as a road by mining equipment, still gets a listing as an 'airport'. We don't have a well-defined category of 'airstrip'. From the field where some farmer operates his crop duster, up to the busiest of hubs, they're all 'airports'. They may or may not be illuminated, may or may not be marked, may or may not offer air traffic control services, which may or may not be radar-equpped, may or may not have instrument approach procedures, may or may not have navigational aids, may or may not have hard-surface runways, may or may not sell fuel, offer airframe&powerplant services, service avionics may or may not offer customs service (sometimes by advance request only) may be public or private ... and so on ... but all of those are attributes that may determine whether a given aircraft or pilot can operate. There's no formal minimal level of service that designates an 'airport'. An "international airport" is a place where you can get customs service on request. In Upstate New York, a lot of relatively tiny flying fields are "international airports" because private planes do cross the Canadian border, and it really messes up the system to have to try to slot them in to operate among the "big boys" at the places with scheduled international service. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
