[Tagging] Feature Proposal - RFC - flight route

The consensus is that the flight path should not be mapped, but we are interested the airport (Stop positions and platforms) where the flight serves.

This is a complex issue.

Lets start from the end user's point of view:

Flight number XXxxx is sold by airline XX and goes from airport ABC to airport XYZ, possibly with scheduled intermediate stops at airport DEF (and possibly more).

That flight is operated by the same airline or by another airline YY as flight number YYyyy.

The actual flight route is not fixed, but is defined before departure by the flight's captain.

The flight route has to follow established flight corridors or tracks, which in turn are not fixed (for example the North Atlantic Tracks [1]).

So what can we map as geographic data in OSM? The airports and that's it. The "The way making up the route" is not mappable, because it is variable from instance to instance of the flight.

The only way out I can see, is to accept as "the way making up the route" fictitious tracks connecting the airports on the shortest route.

(I know that we map already shipping routes, which have, in principle, similar problems.)

Hi Michael,

Read your proposal and have some comments/questions

Regarding travel duration, I think this information is irrelevant in the route relation, which is only a route.

The duration depends on what's walking the route (Paris/NYC with A380 = approx 7h and Paris/NYC with Concorde used to be lasting 3h)

From/to should be derived from relation members (role=start/stop). But it may be desirable to have these data for display or labelling.

What if several operators use the route ? Will we have to create as many routes as operators ?

I use to believe flight routes aren't fixed paths but a bunch of paths which may vary depending on weather, air pressure, etc...

Is this really mapable in OSM ?

You may give a few details more in the Route tracking chapter

All the best

François

Dear all,

I have proposed an extension to the public transport schema to include flights.

https://wiki.openstreetmap.org/wiki/Proposed_features/flight_route

Basically the flight route is mapped just like ferry routes in my proposal.
