To all you guys with the Longitude and seeing this problem, please read on…
I just had the same issue I decribed in my post above flying the SR22. My plane was off to the right of it’s GPS line the whole trip, and the ILS took me down about 100m right of the runway threshold. Or at least would have had I not cancelled AP and flown it manually.
And this made me realize something - what I did differently on my flights with the ILS not working. I hand flew the plane for quite a distance after takeoff vs getting it to a safe altitude and just letting AP do its thing. I remember having hand-flown the Longitude and TBM for a while before punching in the AP when I encountered this issue.
Can you guys potentially test this hypothesis as well?
And to those NOT having issues - please refrain from cluttering up the thread with posts of how you’re not having issues. We know now everyone seems to be affected. It would be nice to have a clean thread to make collaborating on debugging this a bit easier.
