So, to clarify:

How do I get the airport definitions then?

No, don't uninstall and reinstall FlightGear. I apologize for making the suggestion. xDraconian and WoodSTokk are correct.
My last post is asking for their input on a proposed method for getting the airport definitions into your local copy of FlightGear. I have never tried it and don't know whether it will work and recommend waiting to hear from them.
You can always get the airports recommended on the X-plane Scenery Gateway and wait until the next FlightGear world scenery build.

If I understand correctly, you authored these airports within WED. If this is correct, then WED created an apt.dat file for each.

Yes, you want to merge these files into your apt.dat.gz file. Uncompress it, add your two airports, and then recompress it.

Make sure to merge without the apt.dat header (first two lines) and footer (last line).
Within the main apt.dat (the one containing all airports), ensure you merge below the header and above the footer.

Example:
Code: Select all
I
1000 Version - data cycle 2013.10, build 20131335, metadata AptXP1000, further modified by the FlightGear team (cf. <https://sourceforge.net/p/flightgear/fgmeta/ci/next/tree/changes-in-dat-files/apt.dat>).  Copyright © 2013, Robin A.

What do you mean? Which is the right xml file?

Every tile will be build from a stg file and a btg file (3d data).
In the case of LOWW, it is in '/Terrain/e010n40/e016n48/' in the tile 3220098.
There is a file named '3220098.stg'. This is a text file and the first two rows are:
Code: Select all
OBJECT_BASE 3220098.btg
OBJECT LOWW.btg

This means that this tile is based on the 3d date of the file 3220098.btg (you will find this file compressed as '3220098.btg.gz').
And the second line says that the file LOWW.btg (3d data of the airport, also compressed as 'LOWW.btg.gz') should also be loaded in this tile.

If you want include a new airport in the scenery, then you should find the right tile and add the second line in the right stg file, so that FG load the 3d airport data additionally to the tile data.

There is a wiki page: http://wiki.flightgear.org/Tile_Index_Scheme

EDIT:
have it now calculated by hand it should be e070n60/e072n65/4138713.stg

So, I opened the 4138713.stg file, and one the second line, I added:
OBJECT USMM.btg

Is this correct?

I'm not sure because I still couldn't fly from USMM when starting up FlightGear. I did fly past the airport, and only half of it was there.

Thanks

does USMM.btg.gz exist in that directory?

remember, you cannot just add lines to add an airport without the additional work of rebuilding the scenery files and placing them in your scenery override directory so they can be used from there and not corrupt your default installation... objects can be added but airports are not objects...

Yes, USMM.btg.gz exists in that directory. Still 'No matches for USMM'.

is it listed in the apt.dat file? it may be apt.dat.gz which is compressed...

No, it's not compressed. It's just apt.dat.

Do you have a boundary included in the WED file for yo ur USMM airport? If not, it might explain why you could only see half the airport on a flyover. Ground is flattened within the boundary.
Using the Web Airport Generator may be a factor but my limited experience indicates you should see more than half the airport.

I did include a boundary, but I didn't use 'Always flatten'. I'll try again and report. But that's not the main issues, I'll sort out the aesthetics later. I'm concerned why the airport isn't found by FlightGear when starting up (I therefore cannot program routes to USMM).

The match for USMM comes from the apt.dat.gz
I have try it now and included the following line in apt.dat.gz
Code: Select all
1     49 0 0 USMM Nadym

With only this line, FG crashs on start (klick 'Fly!').
I have then added a fake line (for runway) in apt.dat.gz. Now i have
Code: Select all
1     49 0 0 USMM Nadym
100   49.99   3   0 0.00 0 0 0 4    65.82035834  72.09018573    0.00    0.00 1  0 0 0 22   65.83043466  72.10486817    0.00    0.00 1  0 0 0

and the launcher will find USMM. I can also input USMM in the routemanager and USMM is visible on the map.
This means, the data in apt.dat.gz will be taken from launcher and routemanager.
To see the 3d model of the airport, you need to update the btg and stg files.

And i'm cofused why your apt.dat are not compressed.
To edit the file, i have
1) taken a copy for backup
2) unzip the file (gzip -d apt.dat.gz)
3) edit the apt.dat file
4) zipped the file (gzip apt.dat)
and the launcher was happy.
