First to be sure, we’re speaking about the free Inibuild included A310, right?
If so, I think I see. Do NOT use the altitude bug select to interact with the FCU. Delete that one.
But instead assign ones that look like: INCREASE AUTOPILOTE ALT and DECREASE AUTOPILOTE ALT (I don’t remember the names exactly). Then for each of these one do: ON PRESS, scan input and select ALT on your Bravo and turn the knob left or right depending if it’s increase or decrease.
To select ALT (or any other) while scanning input you have to be on the position (i.e. a selection) of one which is NEXT to the one you want. Then:
- select it while scanning (turn button ON).
- Turn the rotary knob in the desired direction.
- Select it back to its PREVIOUS position (turn the button OFF). This simulate on ON/OFF button to release the scanning. Remember you’re doing an ON PRESS.
You should then have JOYSTICK BUTTON 17 + JOYSTICK BUTTON 13 with ON PRESS as action for the desired input. As you have to do it twice for each Bravo control, it’s a total of 10 items to set up.
