Airport specs

AirportTypes shows ID numbers 0 through 9. Can you define more beyond that?

The maximum number of possible airports is 128. All (even overridden) original types count towards this limit.

As there is (currently) no way to define a new statemachine for an airport, any new airport must have the same logical layout as one of the defaults, but may be rotated and may use a different tile layout.

That means I cannot use ID numbers 0-9, but 10-onward which in turn can override 0-9, correct?

I'm thinking:

If you want to modify an existing airport, use its ID and don't set property 08.
If you want to create an additional airport, use an ID > 9 and set property 08 to copy an existing airport.
If you want to disable an existing airport, use its ID and set property 08 to ff.

But try it and see what happens.

That's what I was thinking as well. I just happened to stumble upon NML:Airports while searching for something else tonight and was curious about how to code a few extra styles of airports.
