GI 275 software 2.32. upgrade installed and showing very easy access to the GPSS vs HDG toggle function for the Autopilot. It is now in the first menu level rather than three levels deep. I did not install the alternative option which is a physical panel switch since I wanted to try the software option first. Since the software option works quite well I do not think I will be installing the switch. Need to make more flights in IMC and busy ATC with interspersed deviations to make final assessment. However, based on this flight it appears I will stay with the software option. There were no glitches whatsoever. Easy to toggle even in busy ATC airspace. GI 275 performed excellently as in the past including an RNAV approach. Very happy with the change!!!

I was asked in a PM whether the active leg of a hold was displayed in the GI 275 while also displaying it on the GNS 530W and if it was flown correctly by the autopilot.My setup is a GI 275 ADAHRS+AP as primary ADI and a GI 275 ADAHRS configured as MFD/Standby ADI. They are connected to the GNS 530W and the ADAHRS+AP unit drives the KFC 150 autopilot. They work perfectly together and will fly a hold and course reversal without any issues.This video shows them in action. Regards, Chris Koppel

So recently, on a very long series of flights the following occurred: From LKU to MMJ, my M20J 201's auto-pilot was tracking on course to a VOR waypoint via the Garmin 530W. All of a sudden, the autopilot banked the aircraft to the right on a standard-rate turn off course nearly 60 degrees before I disengaged the autopilot to correct the course heading. I reset the FD and had the same problem. I had to turn off the autopilot all the way, wait a few minutes while hand flying in IMC, then turn the autopilot on again. It worked for the remainder of the flight. From MMJ to Lansing, IL, the autopilot worked flawlessly. From Lansing, IL to MMJ, something weird happened. First, the aircraft started a nose-down attitude and the autopilot disengaged with a beep. I went to turn the autopilot/FD back on and it would not turn on. I looked over to the circuit breaker and it was popped. Cautiously, I pushed the breaker back in and turned the autopilot back on. The autopilot now began to porpoise with the altitude hold on. It was almost like the FD was overcompensating for what it normally makes as slight adjustments in pitch and trim. I didn't seem to have any trouble with the autopilot following the nav course, but once I set the FD to hold an altitude, forget it. Up and down. Each up and down worse than the last. It was a bumpy day and I had to hand fly all the way back to New Jersey and then to Virginia. It was exhausting. Has anyone else encountered the same problems? My theory is that the pitch servo clutch finally went. At the same time, it doesn't explain the drastic turn to the right off course. Maybe that was a fluke with the FD? I've had it do that if I am flying a WAAS RNAV approach when I activate the approach data into the GPS too late. I am far more concerned about the pitch. Ideas?
