Autopilot goes from VOR to ROLL when tracking VOR
-
The autopilot will quite often go in to ROLL mode when flying in VOR mode. Sometimes it happens every few seconds and sometimes less often. This occurs even when the signal from the VOR is very strong, say within 30 miles of the VOR, and the needle is completely centered on the HSI.
Is this expected behavior even when the VOR signal is completely stable? I understand this should happen when the signal is unstable but it seems strange to me that it happens with a stable signal.

I've yet to see this happen myself, but I will be on the lookout for it. Autopilot disengagement due to loss of signal is entirely handled by the native autopilot controller, so I doubt there is much I can do, unfortunately.

@Black-Square I know the real plane doesn’t have this feature but for purposes of trying to catch an uncommanded fallback from NAV to ROLL, an audible alert when it occurs would be useful. The autopilot disconnect sound, for instance, would certainly get my attention. Where would be an appropriate place to implement this pseudocode?
If CurrMode = ROLL and LastMode = NAV then PlaySound(AutopilotDisconnect) LastMode = CurrMode -

If CurrMode = ROLL and LastMode = NAV then PlaySound(AutopilotDisconnect) LastMode = CurrMode@MarkS If you really want to open that can of worms for yourself, search for the following in Starship_Interior.XML
(>L:var_AutopilotDisconnectTone, bool)I'm happy to help with that. I just wanted to give you a quick answer before I left my desk for a few minutes.
