Have had several unprompted autopilot and autothrottle disconnects on my PMDG B737NGX. I have checked basic Saitek Pro Yoke and dual Throttle Quadrants calibration (all OK). My BIOS clock and system clock appear to be in sync (a suggested possible cause). Has anyone had similar experiences?
Also, pre today I used the left A/P, but it would not engage today. The right A/P worked fine. Why? I do not (yet) have any programmed or random faults in my set-up (yet!).
Any information would be appreciated. B)
