Autopilot keeps disengaging NAV mode (VOR-to-VOR navigation)
-
Found the report I was writing about.
Commendable effort on the side of the user, but I think he gave up in the end

BTW. It not happening for me in the F28 and Bae146 might be suggesting that it's about the standard AP units. Both planes are larger and have the AP functions spread over the cockpit, with probably some custom coding involved to make it happen - and not just a standard AP panel.- decided to withdraw the conclusion as I just realized the 114 also has a custom AP panel and it also happened with the Starship
Either way, have some examples from YT (link should point to the specific moment):

On glideslope for some time now, clear view of the runway, APR randomly moves back to ROLL (the popped breaker is not about this, it's an icing sensor and was known).
Here a similar situation:

Normally it happens with VORs, was just easier to remember and find those two.
