Has anyone ever experienced the autopilot disengage for no reason? I was flying the 737-900 the other day when the screen momentarily flickered (as if you changed the view, then back again VERY quickly), the next thing I heard was the autopilot disengage warning!After grabbing the stick the plane flew perfectly normally until the autopilot was reengaged.I think it has happened once in the past, it was a while ago. All I remember was returning from the loo during a long flight and finding my previously stable aircraft (again the NG) broken in bits, it was overstressed due to it falling from the sky. The CMD switch was no longer engaged.I would suggest it's a FS prob. and a rare one, but who knows. Where's the first officer when you need him!Cheers all,Joe Mathews

Are you using any weather add-ons? If so what version?

Has anyone ever experienced the autopilot disengage for no reason? No i have not, there is always a reason. One only needs to be paying attention to the pilot's flight display (FMA), if the A/P gets kicked out or reversion happens it is most likely overspeed, touching the controls in CMD or some restrictions the AFDS cannot handle..Best Wishes,[h4]Randy J.

I can only remember the second instance when it occurred. I didn't have any physical contact with the controls and the aircraft was in straight and level flight, and maintaining a constant speed (it was a nice clear, cold night).As I

No I'm not.Thanks for the quick response, I've just posted the following to Randy J. Smith who also relied to my original:"I can only remember the second instance when it occurred.

Do you have force feed back on a control? Next time it happens look at your PFD and take a screenshot, this will help out a bit.Best Wishes,[h4]Randy J. Smith[/h4]http://www.rawbw.com/~bdoolin/shinault/southparkcartmad.gif[h3]I WANT MY 747![/h3]Caution! Not a real pilot, but do play one on TV ;-)
