Gentlemen:I've been a satisfied customer of PMDG since 2005. Recently I'm experiencing "uncommanded roll excursions in LNAV" for both my 747-400 FSX and MD-11 FSX. These excursions occur in LNAV along a programmed route of flight. Angle of bank reaches 22-25 degrees during a left or right roll. I've tried everything I can think of to remedy the problem. I'm flying LDS 767, Wilco Airbus (all types) and 737PIC with no similar problems. Any ideas out there?Regards,Dave Jarrebh412captainMy last name was cut off for some reason. It's JARRETTThanks.DJ

Thanks, Kevin. Before I posted my issue on the Forum I did run the FS_Registry_Repair.exe file. No luck!The photo I posted was taken after I ran that file. You can see it occured on a flight between KJFK and KPHL.I recently installed several A2A Simulations products. I wonder if there's something in A2A's Accu-Sim code that's affecting my straight-and-level capability when coupled in LNAV via PMDG's a/c?Cheers.Dave J.

Had the wind vector just shifted? Not knowing how far into the event this is I can only assume that the FD steering bars are going to do something, or since I notice you have had a right wind correction if the wind just dropped from 100 kts to 59 kts from the same general direction then the aircraft is taking wind correction out as fas as possible. Watch the relationship between the wind and the heading changes next time.Meanwhile, you are not already please try a registered copy of FSUIPC and use the weather smoothing features in it. Works as good or better than anything else I've tried.

Weather shifts I'm guessing. Watch the wind and temp/pressure and see if large shifts in those values correspond with the excursions.
