Autopilot does not disengage

Recommended Posts

Hello

 

I am experiencing the following issue where I seek for you advice (stock FSX, PMDG 777, ASN, no other addons - win 8.1)

 

The autopilot does not disengage, neither the assigned yoke button, nor the keyboard, nor pressing the AP button works. For the keyboard key, I see the button getting depressed on the MCP, but with no effect. The only way to disconnect is by using the bar, but then I cannot silence the siren as the yoke button has no effect. As additional observation, engaging the left AP always also engages the right one, both lamps come up simultaneously even if I activate only one side.

 

Any ideas?

 

Thanks

Ross

There's your problem.

 

The MCP button only activates the AP.  The button on the yoke disconnects it.  If you're going to tie a key command to the AP disconnect, find the setting in the PMDG SETUP > KEY COMMANDS section of the CDU prompts.

Thanks, Scandinavian, I will try this out tonight. Now, is it right that if I press the left button to activate, the right one comes on as well? Second, I have assigned the yoke button using the FSX settings (same as the Z key), and the same setting I would use the deactivate the autopilot on the Aerosoft Airbus. Is this the right way to do it?

 

Thanks, Ross.

Yes.  The AP is the AP.  There's no CMD A versus B in this plane like the 737.  The different APs are managed in the background.

It could cause conflicts with the 777 because the FSX AP button is a toggle: ON or OFF.  In order to silence the alarm, you have to press it a second time, which could re-engage the AP.  The proper way is to set it up like I did in the video.

Well, thanks a lot for the explanation and the video. Indeed, pushing the button on the virtual yoke did the trick. Also, I was able to assign a key on the keyboard to the a/p disconnect function. Now, how can I assign a button on my physical yoke to this. The FSX settings do not know about that particular function, and the PMDG MCDU settings menu does not know my physical yoke...

 

Thanks,

Ross

Did you watch the video?  It shows exactly how to do this.

 

If you don't have a registered version of FSUIPC, any "joystick keystroke mapper" (in quotes so you know what to search google for) will do.

I should have watched the whole thing (and read the FCOM, which I did yesterday...). Now everything is clear, thanks for this. The only thing that makes me wonder: two years ago with the PMDG NGX I connected the yoke buttons to the FSX's functions AP ON/OFF and AT ON/OFF. At that time, the buttons then did not ACTIVATE the respective functions (as you would expect) so I had to use the VC buttons, but they reliably disconnected them. I made the same settings with the 777 now as I was expecting the same behaviour with the 777, which - as you nicely explained - follows the same logic.

 

Thanks again, Ross

Brilliant Advice, thank you!
