Which airport or ILS doesn’t seem to matter. What matters is that if your plane is off from its GPS path in flight (following it, but flying to the left or right of the path), it will ahve that same offset at the ILS.
If it’s following the path, you’ll have no issues. It seems random to me. Thought I had figured out what broke it, but unfortunately not. ![]()
I’ve had the issue in the TBM and Longitude more than any other, but also had this same issue in the Bonanza and SR22. The symptoms are the same. If it’s not perfectly following the GPS route en route to destination, it will have that same offset when trying to land it.
I don’t know what causes it. And it doesn’t happen very often for me. Probably 1 in 5 flights at most.
