Quirks or Errors on A/P and A/T Systems

Recommended Posts

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)

Shear pin failure. Check the intro manual for an explanation. If you pushed your yoke hardware enough, it will cause that failure. Additionally, if your hardware spikes, this can also cause it.

 

Also, it's a forum requirement to place your full name in your posts. Please do so in the future.
