Cessna 172 autopilot/trim disconnect button?

[KylerHolland]

Hello! I have Honeycomb Alpha yoke which is a replica of Cessna yoke.

I’m trying to assign the button on the screen below to the same button on my actual physical yoke. But I can't find it in the Controls menu. Can anyone help?

Seems like this button on the yoke has two functions. 1. Disconnect AP (autopilot); 2. Something with the trim, I guess. There is no such thing as "Disconnect trim", so probably some other trim fuction? I looked POH for 172 but there is no explanation.

I think the button only disconnects trim.  The thumb switch below it, is the electric trim.

The description is confusing..

The POH says that this "AP/trim disconnect" button basically disengages autopilot and electric trim:

AUTOPILOT DISCONNECT (A/P DISC/TRIM INT) SWITCH When depressed, will disengage the autopilot and interrupt Manual Electric Trim (MET) power. 

 

I guess, I figured it out. The button doesn't work in the game in a correct way. A custom key can not be assigned to it. Will report a bug. I mean you can assign "Disengage autopilot" but it supposed to be a little more than that. The button should also stop 'Manual Electric Trim' (MET) from functioning. In case of malfunction the MET can be switched off and the analog trim wheel can be used instead.

I guess this turns off all "automation" and restores manual control.

This must have been mandated after the 737 MAX problems came to light.. 😉
