Can misc- config settings cause autopilot dropout ?

[ChuckOman 3]

Hi Bryan -

Have enjoyed using the P3D4.5  FS2Crew for PMDG NGXu, and recently transitioned to V1.4 of FS2Crew for A320 running on FSL's v2.0.2.450 (the latest).  Enjoying learning Airbus SOPs and flows.

All going well, except that I've found that my FSL A320 autopilot consistently disconnects after takeoff as I climb  out through 10K-12K ft.  Guessing that something  is happening in FS2C that is inadvertently changing the aircraft climb power settings, and causing the disconnect.  I have to disconnect ATHR, dive to recover the airplane and then reconfigure all the automation to resume the climb.  Doesn't happen when FS2C isn't running .  I'm wondering if my problem is somehow related to my choice of FS2C Config-MISC settings relating to 10k feet transition.  Couldn't find anything specific elsewhere on the forum.

My pages are set this way:

Skip FMGS check at 10K - YES

Perform 10K flow at 18K - YES

Perform 10K clb/des flow - YES

Window shades at 10K - YES

Toggle No Smoking 10K - YES

(Transition level was set to 18K BTW)

Are there any known incompatibilities among these five"yes" choices that could be causing my problem ?  Any other thoughts on what to try to resolve the problem ?

Hi Chuck,

FS2Crew doesn't touch any aircraft internal systems logic.

I suspect your joystick is spiking... try increasing the null zone in your joystick.

If you move the side stick, the AP will disconnect.

Or it could be turbulence related.

Thanks Bryan.  Good suggestion, but I doubt I have a joystick spiking or turbulence/shear problem - doesn't happen in cruise or approach, or if I fly with FS2C is off, or cause issues with other aircraft.  My ASP4 turbulence settings are very low: 0/5/10% per FSL recommendations.  I don't see spikes if I monitor my joystick axis values in the Win calibration window or  by watching for variations using FSUIPC "in" display.

I'll continue to experiment. Would help me troubleshoot if I better understood what the four 10K altitude related MISC options do:

I had chosen: Skip FMGS check at 10K - YES; Perform 10K flow at 18K - YES;  Perform 10K CLB/DES flow - YES; Window shades at 10K - YES

With these choices, should all the 10K flows move up to trigger at 18K, including CLB/DES and the window shades ? 

If I had set the Skip FMGS check at 10K to "NO", should the FMGS check also move up to trigger at 18K ?

You can experiment, but those FMGS options have nothing to do with the autopilot.

Try it without Active Sky.
