So this has never happened to me. Flying the A320neo at fl380 on autopilot. I’m on my phone passing time. All of a sudden the plane goes into an inverted uncontrollable spin to the right and I can’t get out of it. I ended crashing which I never do. Looking back at it I’m thinking maybe it was my Logitech joystick going to sleep. Is this possible? I couldn’t seem to get control of it. But if it did go to sleep what would cause the plane to roll over? I’m at a loss.

Hopefully, this will be something that “can” be avoided after tomorrow and SU11 update.
A new feature in SU11 could stop that happening… but only when Plane you are flying has had its AP code ( .cfg file), updated to take advantage of this fix for the AP PID.
For Example: The C172 Classic’s KAP140 AP should, no longer do this after the SU11 release.
Ref
systems.cfg
pitch_pid_reset_mode
roll_pid_reset_mode
So it’s a bug. If it’s fixed tomorrow that would be the quickest turn around time for a bug fix haha. Wonder why I haven’t seen it before?
OH, if only so .. It has taken many months and endless hours of communication with Asbo, to get them to recognize this PID bug, explain it to them in detail, and suggest how to fix it, and for that fix to finally make it into a SU,.

Well thanks for that!
I know people are assuming it is a bug but it wouldn’t be the first time normal behaviour was called a bug here.
What is your pitch and speed when it stalls. Sure that is a little below the aircraft max altitude but there are of course good reasons why an airliner will stall before its max designed altitude. Often well below.
Nobody said anything about the plane stalling. Mach .78 pitch level. No stall warnings. This is a hardware issue with the joystick.
In theory, a “Noisy” Pot in the Joystick, could cause an apparent movement of the Joystick, thus disconnecting the AP, resulting in the plane flying in an unattended, uncontrolled state.
Plenty of good, free Joystick Test & Calibration tools , to test a potentially defective Joystick / Yoke.

Looking into that now. Installed the Logitech software and seems the twist (rudder) is just a little to the left when centered. If I remember right, I think I need to use a screwdriver to get it centered. I still don’t think that’s the issue. I looked in device manager and the USB Host controller is set to allow the computer to put the device to sleep to save power. Not sure what this should be set to.
100% should NOT be set to go to SLEEP mode !!
I’m thinking the same. I can also give the rudder a little bit more of a dead zone.
Not sleep mode, I agree.
Another quite common issue with sleep mode is a CTD caused when the controller wakes up.
