On the past few flights I have experienced that the autopilot disconnects on a seemingly random point in the flight. The autopilot disconnect comes with a disconnection of both yaw dampers and a subsequent continuous left/right turn nosedive. I have seen reports of similar behavior of the Challenger, however, it was on MacBooks. I am running Windows. Furthermore, this behavior has been seen across all updates.
The disconnection of the autopilot often happens on what seems to be sudden turbulence / weather change.
Both logs are attached.
