Hi all,
I cringe asking about this after reading numerous and similar issues a few yrs ago but here is my problem which I could not figure out from previous posts:
I fly the JF Piper Turbo Arrow iii for about 4 months and the GTN750 has been working great. All of a sudden the GPS stopped sending signal to the auto pilot. I happened in mid flight.... As a separate data point, the heading bug actually turns the plane while in GPS mode which it didn't do before (like it was in heading mode). I know how to use the plane/750 so I know its not a matter of the selecting GPS on the 750 or nav on the AP, etc. I also do not think its the little nav switch under the AP in the plane which is inactive.
The stock garmin 530 works fine so Im guessing its not the plane, the sim or the auto pilot. The GTN750 also works in my two other planes (Torqism SR22 and stock c172/REP). I tried to change some setting which I think is the issue but nothing works.
I also reinstalled the plane and the 750 as well as usually suspects like rebooting pc, etc
Any help would be greatly appreciated as after flying with the 750 I just cant go back to the 530.....
Thanks in advance
Paul
