Has anyone encounrted this issue?

I have after attemptinng completing a trans atlantic.

I can't really determine what the source of this issue.

But can tell my plane entered A.Floor and the autopilot was disconnected. As i was AFK from PC.

Having the exact same issue

I'm having the same error

Same issue

The issue is, a weather event, sudden change in winds, has caused your AP to disconnect. 

Same here. From volanta graphs I doesnt look like my plane encountered severe turbulence or anything that would make AP disconnect, everytime I experienced this I was in the -1000 over Atlantic

For me the aircraft is unflyable.  I have gone through the update process including the latest .04 version and my flights end up with a similar out of control death spiral.  I have searched the forms and this is the closest topic that seems to relate to this problem.  All of the improved art work and nice screens do not help me control the aircraft when I am trying to fly.  Like most of us I have been flight sim- ing for over 20 years and do try to follow all of the suggestions, including checking all of my hard ware.  When a problem only happens with one aircraft that seems to point to a problem with that one aircraft.
