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

Once SkyDemon has outputted a route in GPX format you're free to do whatever you like with it, it's just a file.

Great, thanks.
Regards,
Philippe

Here is the script if interested - needs python 2.7 installed
