Hi,
I have been using Airtrack for several years with no issues. Just recently, X-plane is ignoring all Airtrack fmc inputs, but the Airtrack Efis is working okay. I have installed the most recent plugin, and deleted X-plane prefs. I am using the latest Navigraph data.

Hello,

This might be related to the plane you're flying (try with a different plane) or it might be related to a latest version of X-Plane, I'll have to try.

By the sounds of it, AirTrack still keeps the flight plan so at least this will work, but if not, there is a setting in the Settings App of the iPhone or iPad (the one from Apple) which if you scroll down to AirTrack, you'll be able to enable FMC Flight Plan standalone mode which makes AirTrack work independently. Or it may also be that you already have this enabled and hence the behaviour.

I'll test soon with the latest X-Plane but in the meantime please use standalone mode and if you can let me know which plane you fly I can try and replicate it.

thanks and sorry for the limitation,
