Altitude hold selector

Hi

I am constructing a switch panel for my son, using an Arduino and he wants an encoder rotary switch for the adjustment of the auto pilot altitude.

I am after assistance in the keyboard controls for the altitude hold sector increment and decrement, I have found that Ctl-Z is for the altitude hold switch, but cant find it for the adjustments.

I apologies in advance as my knowledge of flight simulator is limited to plane goes up and in my case comes down.

Thanks

There may be an easy keybpard command. I don't know, and can't look it up right now.

But I think when making a controller like that, FSUIPC would be a great asset.

(FSUIPC, with a registration. (payware))

In that you have the option to assign all sorts of commands. (Many of which aren't available normally in FSX.)

And, even btter, FSUIPC has an option to register a keypress or mouseclick, and analyse for you what command it sends.

Using that you can: click the clickspot in the VC, and FSUIPC tells you which command was fired.

good luck on the panel.:D

These are events AP_ALT_VAR_INC and AP_ALT_VAR_DEC.

Note that you cannot assign keystrokes to them via the menu ..

Either use the FSUIPC (registered) or manually edit the file Standard.xml (with e.g. Notepad) that holds all keyboard/controller assigments.

This might NOT be 'right' but what if you use Pitch Trim? You press 'Ctrl+Z' to disengage Alt Hold, dial in some trim (with your 'encoder rotary switch') to climb, and when at Alt desired you press 'Ctrl+Z' again to engage 'Alt Hold'. Wala! The 'sweet' part of this 'trick' is that the sim will 'auto' set your trim back to the correct trim for cruise. Too easy? Gauges and XML would personally drive me crazy.
