Catherine,
Not quite the answer you seek, but following to Sids comments. My advice is
keep any thing you want generic to your setup away from aircraft model nasal
if possible.
If it helps,
I used xml for controlling "some" auto pilot functions via Joy stick control
to avoid fooling around in nasal. I have attached the xml file for you as
info.
Some notes that should be in the file:
The file is based on commands given to execute button presses in the 737
autopilot panel xml file.
The trigger on button 0 is used as a shift function so the top hat left to
right moves the heading, then shifted moves the course.
Likewise un-shifted one of the buttons selects heading mode and shifted
selects vor mode.
I ran it inconjuction with the older 2d AP panel in the 2005 era 737-300
model, I am not sure about the new 3d panels.
However its not panel dependent, it drives the autopilot setting and lock
properties directly. and runs ok againt the current v4.5 737 series
autopilot xml implementation or the basic generic FG autopilot on the
current FG git version.
I "think" it would run ok against any model, but would not promise it as i
only use the 737 implementations. As far as I recall there are no funnies in
it unique to my sim setup.
