Autopilot not engaging

[GAPlanesOnly]

I'm trying to learn all the quirks of this model. On my flight today from 07FA to KSGJ, I couldn't for the life of me get the AP to engage even though all seemed in order with regard to Vert Gyro in Norm and Pedestal control centered. The AP light would remain green, the EADI would show AP ENG, but the aircraft would not respond to the AP inputs (heading, VS, or IAS). It was like the servos were not enabled. After 50 minutes of trying to correct the failure on air, I decided to divert to KMLB and call it a day.

Attached is the log file in case it helps diagnose (not sure if related but there was an interesting message in there at "2024-12-28 11:39:44 CJ525[honeywell_autopilot.cpp:233]: VG: No Servos when in VG1 invalid". Not sure if this message got in there while I was trying to debug and triggered the breakers mid-flight.

What could drive this behavior? The circuit breakers for VG1 and VG2 were pushed in. 

Thanks!

ps. tried again, same results, must be something I am overseeing.

That call only looks to have been reported once, it would repeat on each attempted engagement if that was the case. Most of the other forced disconnect methods typically will output to the log, but I'm not seeing any here which is somewhat indicative of the turn knob not being fully centered. What FD modes were displaying on the EADI?

I have done a second trial, and the same issue remains. Included pictures from the flight deck and a second log file. The FD modes are HDG and ALT ( AP ENG lit on the EADI) but the aircraft remains climbing and tilting to the right while the heading bug is to the left.

I have the same problem, the autopilot only works randomly, I have not yet found out why.
I can't see a red line, sometimes it works, sometimes it doesn't

Problem solved! It's easy - just use the x-plane menu “Developer” and then reload the current aircraft - done and the autopilot works perfectly!!!!

Indeed that works, thanks! Attached is the log file in case it helps debug the issue.
