Hello Guys,

when I fire up FMGS the transponder mode is MODE C and TCAS is TA/RA; JL already told me he does not want to change this default state to STBY, even if I think that most of us start the airplane cold & dark ...

Anyway, if I try to assign a switch with the offset x7B91;1 - the result is: nothing happens when I press that switch. The transponder mode should change to STBY, but it doesnt work. Same with the IVAP: if I change the transponder in IVAP, nothing happens in the MCDU.

So the question is: is the MCDU a "write only" function? Is it not able to read the transponder state from FSX? Or am I completely wrong?

Thanks for all your help!

Stephan

Stephen, I'll take a look at it later and see if I can confirm the problem, if it helps that is. :)

I believe the only way to control the transponder is with the MCDU at this stage.
