Thank you for your reply. Unfortunately, that’s not what I’m looking for, because the variable you mentioned represents the transponder STATE itself — meaning whether it is ON, OFF, ALT, or STBY (and in some other transponders there is also a TST state).
What I am trying to get is the currently selected function that is chosen using the FUNC button on this device. These are additional features such as count-up timer, count-down timer, countdown from a preset time, pressure altitude, total flight timer, outside air temperature, and density altitude.
I suspect this is not covered by the default simulator variables, since this seems to be something more custom and specific to the Garmin GTX 327 itself. However, since the functions visibly change on the virtual display of the transponder, there must be something internally that holds the state of the currently selected function.
