That's an interesting problem Joe as I believe the demo includes mesh as well so I would have thought the airports and mesh would line up.
I'm downloading now so once installed will check that out.
PS. Does anyone know if this overwrites any default files? ie landclass textures like FTX Global does or autogen or trees. And if it does then are the originals properly backed up? I think when I do install I will have to try it to a dummy FSX folder just to see exactly what happens.
EDIT: Finished the download and installed to a dummy folder. It seems the landclass textures are stored in ORBX folders so that is good. Bit disappointed to see some model libraries installed to Scenery/Global. Very disappointed to see some of the texture names used by these model libraries. Textures such as lighttower.dds or green.bmp. It is good practice, if installing anything to a default FSX folder, to at least use unique names to avoid the risk of overwriting anything. Generic names like lighttower or green is just asking for trouble.
Following is a list of the files added
Effects (some orbx fx)
ORBX (most of the files go in here)
Scenery/Global (some model libraries as mentioned above)
Scenery/World (looks like AFCADs for BIxx airports, these are needed to adjust the airport elevations due to a bug in FSX)
Sound (A handful of ORBX sounds, properly named)
Texture (4 autogen building textures, looks like the names are unique though not tagged as ORBX)
Weather/Themes (some ORBX weather themes)
