Hello!

I have really enjoyed using both my Airfoil Labs KA 350 and TDS GTN 750. I keep running into issues where either my GPS units wont render in, or when they do the crossfill will not work. I have gotten a few really great flights out of my two products without issues however these problems keep appearing sporadically. I have tried completely reinstalling both addons several times and I still have issues. I would appreciate any help/advice! Thank you Smile

Hello,

While there is no official TDS GTNXi XPlane integration into the Airfoillabs KingAir 350, we will do our best to assist.

Please let us know of the TDS GTNXi XPlane and GTNXi PC Trainer versions used as well as the antivirus.

When you say that either GPS units will not render, exactly what do you mean? Please provide us with details.

I see okay! It seemed to work just fine for quite a while however now it wont show up to replace the default integrated Garmin 430W's. The old avionics remain. I also use default Windows antivirus which I don't see would be an issue as the G750's work great in other aircraft! Below I am attaching the versions of software I am using too!

Aviation Trainer: V 3.10.3.0

PC Trainer: V 20.42.2.0

X-Plane Plugin: V 1.0.15

I'm not sure if there are any plans but I would love to see future integration for the KA 350!

Thanks in advance!

Hello Ewan,

The TDS GTNXi XPlane versions are fine. Do you have Legacy VC Integration enabled from the X-Plane Plugins/TDS GTNXi/General menu?

Sorry for the late response, definitely has been a hectic week!

Yes I do have the integration enabled Smile

Hello,

In this case, with X-Plane closed please delete the TDSGTN.ini file located inside
\X-Plane 12\Aircraft (Airfoillabs KingAir directory.

As well as let us know the exact aircraft that you are selecting from within X-Plane.
