I was doing a flight from RSKI-KSFO and about 7 hours into the flight the plane randomly dives. Normally I would think the autopilot deactivated, but from what I saw in the ATC logs, maybe not. This caused 3 violations, and in which I won’t be able to access the Expect Server for 24 hours. This is no big deal, I was just excited about going to FNF for once. I still can, but very late.
Over all there were 11 “Autopilot disengaged, check flight parameter” messages These messages appeared shortly after the dive started.
I have a video but it won’t let me add it.
