please provide a track file or video Autopilot Pitch Inconsistency

[RichW]

On some missions both ALT and ATT refuse to work with the auto pilot. The autopilot engages but does not maintain pitch. Steerpoint and Heading works okay. Is there some weight, speed or other parameter that would cause this to happen although heavy loads work sometimes and light loads don't.

Thanks for any ideas,

Richard

I only find it struggles a bit at high altitudes (above FL350) or above M1.0, or, with an out-of-trim loadout.  It struggles to maintain a coordinated turn if you are heavily asymmetric.  Once you manually trim the aircraft it works ok again.  No idea if this is how the real aircraft behaves though.

Just speculative:

Since the AP can't control thrust, it may run out of the neccessary energy to hold a certain attitude at a certain altitude. You may need to add thrust to enable it to do its job.

Personally I have no issues with AP, since I know inside which parameters I have to use it (alt or att). There are limitations you have to be aware of, and if you are aware of them, it works like charm. Its all well explained in Chuck's manual.

The documented limitations are one thing (and mostly incredibly obvious).  They don't however mention any altitude, speed or asymmetry limitations, even though these do seem to be a factor in-game.  The failure to maintain pitch within the proscribed limits is the issue the OP has reported, not in incorrect flight regimes.  At least, that is how I read it.  I don't think anyone is trying to engage George while inverted, gear down, with a FLCS failure.
