Lately I have been having problems with planes crashing, namely PMDGs 747, all of a sudden. Climbed to cruise and have autopilot engaged(VNAV, LNAV) everything ok, got out for a walk, or last time, gone 30 seconds to the bathroom, returnes and find the aircraft at the gate and Radar Contact telling me that's not my assigned altitude. =) Seems the flight reseted. This happenes 2 out of 3 flights. Asked at PMDG forum for any tips and Dan Downs there told me it could have to do with sudden pressure drops or temperature drops.
Flying PMDGs 747, ASv 6.5, FSUIPC 3.90 registered, Ground Enviroment PRO, Radar Contact 4.3 and Track IR
