Hi,
I was delighted to find out that SkyDemon connected to X-Plane after purchasing it.
I noticed though that none of the export formats were fsm.
I wrote a small script that converts GPX to FSM (not perfect but working) and my question is.
I chose GPX since it is a documented format and I assume I can legally do that; is there a SkyDemon policy that says otherwise ?
Also: would it make more sense to use one of the other formats as input instead.
Note that I would be glad to share that script once stable.
Regards,
Philippe
