I’m writing to report an issue with my A321. @chris_s sent me to the #support board. I’ll admit that I turned around to grab a soda while this happened, but essentially I was flying fine in clear weather and enabled the autopilot features (airspeed, altitude, heading) without issue. But, when I came back to my iPad Pro moments later, my airplane was in a free fall with all autopilot features disabled and apparently speeding >150 KIAS (while under 10,000 ft). This caused me to get -2- separate speeding violations.
Can you please advise what may have caused this? The weather was clear, so I cannot attribute that. It was also flying just fine when I turned on the autopilot parameters. The airplane doesn’t usually have this issue. I’m baffled as to what happened. I’d appreciate any advice in case it was my own handling that caused the autopilot to go awry…I’d also appreciate if you can remove the -2- speeding violations as these were obviously not intentional. I couldn’t regain control of the aircraft once it was in this free fall.
Here’s the replay video…
