How to set ASOBO ATR-42, 72 Transponder Modes via simconnect

Hello, there.

I would like to set transponder mode of asobo ATR via simconnect. (change modes between STBY,ON,ALT,TA,TA/RA)

but with ATR, these modes can be changed by clicking MFD pannel. so, I cannot figure out which sim vars are related just by looking at ‘behavior tool’ with CTRL+G in developer mode.

could anyone tell me the related simvars or guide me how to find those values?

thank you in advance.
good day!

Hi @younghoonee71,

You want the TRANSPONDER STATE simvar, the documentation for which can be found at the very bottom of this page: Aircraft Radio Navigation Variables

Hope that helps,
Matt

sorry about my late response.
first, thank you for your answer.

but, ‘TRANSPONDER STATE’ simvar does not work with ATR. that was why I posted this topic at the first time.

good day!
