Has anyone been able to map the autopilot disengage lever to a button or switch?

[JH2022]

I've tried multiple sim events, LVARs HVARs, etc. in Axis and Ohs, but I can't seem to get the flippin' thing mapped to anything. I have the HC Alpha and Bravo, as well as the Thrustmaster TCA Airbus throttle (that I just use for extra buttons on the 737). Thanks.

Yes without issue.
check the welcome (I think it’s called) documentation and search for autopilot - it gives the exact name of the control command you need to bind.

sorry not home so can’t check now

Did you already reach out to the AAO dev for the beta version of it that exposes PMDG events? https://www.avsim.com/forums/topic/6...7-msfs-in-aao/

The more fundamental question might be, what exactly are you trying to accomplish? If you just want to disconnect everything, can't you just use the standard AP Master On/Off toggle function?

The default MSFS function for AP master will just re-engage AP, which is kind of annoying if you click one too many times to cancel the AP alarm.

Right from the Introduction document:

This has worked for me in my 4-5 flights so far. It's also the standard MSFS default for AP Master On/Off. I have it mapped to a button on my throttle quadrant currently.

I have no idea what you're trying to prove to me. It re-engages the autopilot if you click it a third time. I'm simply stating that one reason to map a button to the AP discon on the yoke is to avoid that. Sorry you went and grabbed that screenshot for no reason.

Why would you click it three times? If you click it per the Introduction document, it disconnects and silences the alarms. Isn't that the end goal here?

By accident, obviously.

I personally chose to not even click one time and then post my failures here asking for help so I can get angry at people trying to help

Well - that's EXACTLY what would happen on the real aircraft too. It can't read your mind and determine what state you want it in, then disregard the number of presses you made and do what you were thinking. Like the real aircraft, you need to press the buttons the correct number of times.

On the 737, the AP disconnect button the yoke only disconnects the autopilot. That's the button I'm talking about.

[Schmegg]

Ah yes - I see - my apologies. I get what you mean now. LOL - bit slow on the uptake. XD

I have the disc button mapped to my throttle and I just press it once. It will disengage the autopilot and I get about 3 whoops of alarm and then it silences it.

It probably should be two presses but I think a 2nd press re engages the AP.

So not entirely realistic but it gets the job done

[JH2022]

How were you able to map it?

[AndyW]

I'm away from my PC but it was just a case of assigning that function to the button. No external software. I have auto throttle and autopilot disconnect mapped, they are options within FS2020 and they work for me.

[737NG4EVER]

I use the payware version of FSUIPC and map it to my throttle quadrant button this way: in Button & switch Assignments (profile specific if you have on) press the button you wish to map, then click Select for Fs control, then in Control sent when button pressed, search for Rotor Brake and finally in the Parameter windows type 68201, finally, OK. There you go, when pressing the mapped button you'll see the autopilot disengage button moving in the VC's yoke.

Alex, until such time as PMDG can enable custom key assignments in MSFS2020, mapping the default in-sim commands is the only way to have hardware assignments without additional software like axes-and-ohs (not my area of expertise!). This comes with limits as the in-sim command is a toggle. PMDG managed to simulate the two-press function at least, but a third press will obviously re-engage the AP. It’s a fairly straightforward matter to press the key twice and twice only.

[JH2022]

Thanks for all the feedback. FYI...flightsim.to just posted some updated scripts which allowed me to map everything on the Bravo.

[Solito]

I use a CH Yoke and had mapped the AP and the AT to yoke buttons as the real thing Not using FSUIPC

[jrw4]

We may be overthinking this. My configuration doesn't require FSUIPC (or AAO, etc.), just two joystick button assignments via the existing MSFS control options:

AUTOPILOT ON (ALT-Z)

AUTOPILOT OFF (SHIFT-ALT-Z)

The keyboard assignments are included inside the parentheses to help clarify that neither of these two commands are the traditional TOGGLE AUTOPILOT MASTER (Z) command.

So far, at least, these two command assignments seem to work fine.

Hope this helps.

Wow, that worked! How did you ever figure that one out?

Steve, in the community folder where the 737 is installed (Documentation, PMDG), you'll find the three variations of .xml's. In the PMDG_NG3_VC_700.xml, you can search for: Left Autothrottle Disengage Switch. It will have an ID number, 682. To that number add 01 for left mouse click or 02 for right mouse click. The PMDG 737-700 uses the rotor brake control with the parameter indicating the actual custom control. So you can assign whatever you like to a controller/joystick/yoke button this way. Andre from FSUIPC forums gave me this Rotor Brake tip.
