A/T disconnect

[z0civic]

Is there an actual command or dataref for auto-throttle disconnect? The best I have been able to do is 

ixeg/733/MCP/mcp_at_arm_act 0

But that just switches off the A/T all together (disarming it). The default X-Plane one doesn't seem to work for me.

don't have my sim computer on at the moment but the answer is in the manual…

I love hand flying this plane.  Use these commands often!

"click", "click" - ixeg/733/autopilot/at_disengage

"click", "click" - ixeg/733/autopilot/AP_disengage

go to the aircraft root folder / documentation / 2-interface guide.pdf

Starting page 15 you have all custom commands you can map to keys/buttons of your liking.

-You can move up/down the mcp switch for arming disarming A/T

-you can engage TOGA button pressent on the  throttle levers on the real thing

-You can disengage A/T by pressing the A/T disc button on the sides of the throttles as well

 

All you are looking for to mimic pushing the buttons like on the real thing is there.

Interesting, so even using the command

ixeg/733/MCP/mcp_at_disengage_act 1

(which is what fires when you push the button on the throttles) it trips the A/T arm switch on the MCP. Is that how the real plane works too?

 

Edit: It is indeed how the real plane works. http://www.flaps2approach.com/journal/2014/9/2/b737-autothrottle-at-normal-and-non-normal-operations.html

A/T disengage button on throttle thrust lever.  Depressing this button will disengage the A/T and disconnect the A/T solenoid switch on the MCP.

Except that the basic AT commands are both missing and out of date as of 1.04.  

To program a joystick, use command I mentioned earlier and will mimic th A/T disengage button.  For TOGA use default "sim/engines/TOGA_power"

You can also write a small script in FlyWithLUA to temporarily "re-add" the missing commands. Then you map them as usual through the X-plane Joystick & Equipment menu.

Jan said that you never disengage A/T during normal operation, you shoulkd just press on N1/or speed to disable the AT and synch the ghost throttle and you are good
