@LorbySI will have to answer your first question (I suspect scripting is involved) but as far as #2 that’s entirely doable and combos are going to be the subject of my next guide…which I hope to write soon(ish).
In a nutshell, here’s how I set up encoder #5 to increase alt in 100s and 1000s.
100s:
1000s:
You create two assignments for increasing ALT. One goes by 100, the other goes by 1000. For each, assign a combo button (in this case, clicking the encoder).
For the 100s, note that I have both “Suppress Key Down Event” and “Is Toggle” checked.
For the 1000s, only “Is Toggle” is checked.
Repeat for decreasing ALT. You can also do this for the NAV and COM radios, switching between MHz and kHz.
It took me a little while to wrap my head around what’s going on here but with careful reading of the AAO manual and some experimentation it started to make sense.
Eventually when the SDK gets improved, I hope to have an encoder that will work for the FMS dial and be able to switch between the outer and inner dials.
Hope this helps! I do plan on continuing with my guide but it’s difficult finding the time right now.
Cheers!
