I recently added the runway for the abandoned Usibelli airstrip in Alaska, but I wasn’t sure the best way to map it. The aeroway=runway tag can take the “abandoned” lifecycle prefix, but the aeroway=aerodrome wiki page doesn’t mention it. Given it’s absence, I wasn’t sure whether it was permitted. Abandoned runways don’t seem to show up on most map layers either. I found one previous thread on the topic, but it wasn’t particularly detailed.
If all traces of the airport are missing, then of course it shouldn’t be on OSM, but there are plenty of remote airports that were never redeveloped and remain undisturbed.
You can add the abandoned lifecycle prefix to pretty much any tag if it makes sense to do so, i.e. if there are some remains of the feature but it is no longer in use. It doesn’t have to be explicitly mentioned on the wiki page.
If there are other remains of the airstrip left, aside from the runway, e.g. buildings, aircraft shelters, service equipment, etc… it’s probably fine to tag it like that.
https://wiki.openstreetmap.org/wiki/Tag:aeroway%3Dairstrip might be more appropriate than aeroway=aerodrome? If it really is that small and there are no other recognizable features left aside from the runway, just tagging the abandoned runway might be better.
Wonder if disused: may be a better option then abandoned?
A number of ex-WW2 airstrips that I’ve seen in the Australian Outback are still as they were built - a strip of graded, compacted, gravel (except now they have a few weeds / bushes growing out of them!)
Usable for light planes (they were usually originally fighter bases), as long as the pilot accepts “higher risk”
Airports needs the facilities to handle planes and a “license”. I would think we are talking about the situation that there is no “license” but the facilities are maintained enough.
