I was once asked to fly a check flight in a Bellanca Viking, which had not flown in a few months, just make sure everything was working. While up, I decided I should check the autopilot too. I set everything up, heading bug on present course, and switched it on. Bellanca Vikings are fairly crisp maneuvering planes, and I was reminded of this as the roll angle commanded by the autopilot passed 60 degrees - too steep! I disconnected it. I decided that to properly report the defect, I should see just what it would do if allowed. The second test I aborted as the roll angle exceeded 120 degrees. I snagged it.
If you have an auto pilot you know and trust, excellent. If you don't quite know and trust it yet, get to know it in severe clear first!
