I am aware that, after disconnecting the autopilot, pilots need to press the red button on their yoke in the cockpit. Is this the only way to cancel the AP disconnect warning? Is there a key-shortcut to virtually press one of the red buttons? Can users bind it to their hardware?

And: shouldn't the autopilot also disconnect when either side's pitch trim is activated? The developers probably have access to the entire FCOM and can have a look.

Hi, the default AUTOPILOT OFF command in MSFS settings should work for you, as it's the one I use myself. As for the pitch trim, I'll get someone to check for you

I bound mine with the control named "TOGGLE DISENGAGE AUTOPLIOT", when I press two times on my binded key it works perfectly.

Hope it helps

Thanks guys, that was the solution!

It may be worth adding this information to the FAQ:

I just got my hands on a complete FCOM of an A310-300. Indeed the AP will not disconnect when either electrical trim switch is actuated, because the electrical trim switches are supposed to be inhibited as long as at AP is engaged in CMD mode. Reference chapter 1.09.12.
