The X-Plane Air Plugin This allows X-Plane to be used with AirTrack. It requires X-Plane 10, 11, 12 or above. Just download the plugin and copy the HaversineAir folder to your "X-Plane/Resources/plugins" folder. If you have any problems see the INSTALL.txt file for details. That's all, you don't need to configure anything else, just launch X-Plane and your flight should show up in AirTrack.
The Microsoft Flight Simulator 2020 Air Plugin The plugin for FS2020 comes in the form of a standalone HaversineAir.exe command line tool.
