Hi,
Are you reading the TRANSPONDER IDENT simvar for this? I’d like to implement this in the A32NX. How do you interpret the various states of the TRANSPONDER STATE simvar?
-e- implementation: https://github.com/flybywiresim/a32nx/pull/6697
The logic is:
TransponderOn = mode switch = ON, or AUTO and airborne.
A:TRANSPONDER STATE:1 simvar =
0 if transponder is not powered
1 if transponder mode switch is STBY
3 if TransponderOn and ALT reporting off
4 if TransponderOn and ALT reporting on
5 if mode switch = AUTO and on ground (mode S)
A:TRANSPONDER IDENT is set true (via K event) when the transponder is ON or AUTO and the ident button is pressed (MSFS resets it after 18 seconds).
Does this line up with your implementation?
Thanks,
Mike
