Robin, Tyler and I have been going through the airports that have been sent in since X-Plane 10.25; the good news is that there are over 350 batches sent in!*
But – I had to throw thirteen of them overboard; they were using OpenSceneryX. For airports that are going to be sent to the gateway and become part of the default airport file for X-Plane, you can’t use third party libraries! Everything you use has to ship with X-Plane.
WED 1.3 has user interface features to help hide third party libraries, but in this case you’d think that having the objects in the opensceneryx/ folder would have been a hint.
It’s not a coincidence that this was the same thirteen entries not sent in the right format; WED 1.2.1 won’t do an export for the global database with third party libraries, and this will be true with WED 1.3 as well, where the export is uploaded directly to the gateway.
