• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Apt.dat usage and license

Hi,

I’m curious if anyone has any info on usage restrictions of the data in apt.dat regarding distribution of derivatives? In the most recent specification of apt.dat it is mentioned that the data is GPL and usage even for commercial applications is welcome. However, afaik apt.dat is only available currently with an X-Plane install and thus basically the X-Plane license applies. Bit confused here.

Cheers

Edit: referring to the global apt.dat here, that ships with xplane

The apt.dat may be shipped with X-Plane, but if the data itself is licensed under the GPL, said license applies.

As far as I know, the GPL-licensed FlightGear also makes use of X-Plane's apt.dat data for its global airports and Laminar Research is fully aware of that.
