Hi,

In the yesterday update of the BAE146 pro, the AUTOPILOT RADIO ALTITUDE MODE control assignments has been added for controlling autopilot ALT ARM mode.

But I did not find this control assignement in the list of the autopilot commands

Did I miss something?

As a workaround I assigned "R" in MSFS to the AUTOPILOT RADIO ALTITUDE MODE control and assign "R" to a button of the MCP combo but did not work as well whereas "R" typed on keyboard make it....

Thanks for your reply

I don't think that this is an SDK sim event. More likely an LVar or BVar, that you have to find the name of somehow. I'll get the 146 update tomorrow and take a look.

The AUTOPILOT RADIO ALTITUDE MODE is a MSFS control assigment, I did not know it either before this update 😉

That is not the same thing. What you can do in the simulator controller assignments and what AAO is allowed to do over the SimConenct API are not the same. Not even close, in MSFS.

Ok I did not know that.

I am trying to assign this command to a MCP combo II. 

As a workaround I assigned this command in MSFS to the letter R of the keyboard.

I then assigned R to a button of the MCP combo but it does not work (see picture above)

It is probably better to use a script. Virtual keys only work when MSFS has the focus, and with a script you can force that to happen (with the FOCUS: command followed by a short SPLIT:)

How do you set this mode in the cockpit? I have been looking up and down through the behavior files, and I can't find any mention of a button with this label.

It is the ALT ARM button just next to ALT sel rotary button ;-)

This LVar script toggles the ALT ARM button:
1 (>L:MCP_Alt_arm, Number)

And this tells you if the button is illuminated:
(L:MCP_Alt_arm_il, Number)

So what happend in the update was, that JF added an internal binding to a MSFS controller action that has nothing whatsoever to do with the actual use case (altitude select) - but is not used anywhere else - just so you can actually control "alt arm". I could have searched for this until the end of time without finding a clue - the crucial information was, what button in the copckpit it was that you wanted to use. Please make sure to always include this information...

Pushing this button through AAO has been possible from day one, by using the LVars that actually switch the button. I was looking at their behavior code to find that out, but you could also do this by running "Scripting->Read LVars from sim" and then filtering for "alt". And apparently JF uses the "_il" scheme for all their buttons, so this is a good way of finding out if that button is currently activated (in case you want to implement On/Off functionality instead of a toggle).

Thank you for this info!

"the crucial information was, what button in the copckpit it was that you wanted to use. Please make sure to always include this information..."

I will do so in the future ;-)
