Find out if Transponder has failed

[kzuerner]

Hi Pete!

 

I am useing Prepar3d V2.4 with FSUIPC 4.936a

 

For tests I am trying to create a little program that informs me when the transponder has failed.

 

Reading your documentation I would expect either bit 0B6F or 3BE4 (or both?) to be "1" when I set the transponder to "failed" in Prepar3d.

 

But none of them changes from 0 to 1 (I am looking them up with FSInterrogate)

 

What do I do pissibly wrong?

 

Thanks for your reply

 

Regards

Both of those are set when the SimConnect variable "PARTIAL PANEL TRANSPONDER" is true (non-zero).  The "partial panel" Simconnect variables sometimes only indicate when the DISPLAY is disabled or covered -- eg for training purposes. I'm not sure if that also includes actual unit failures, though the description in the SimConnect documentation does mention 'fail', thus:

 

PARTIAL PANEL TRANSPONDER Gauge fail flag (0 = ok, 1 = fail, 2 = blank)

 

You'll see in the Offsets Status list that most of those failure flags have question marks against the Read/Write columns. That means that they've not (yet) been verified as working.

 

You can log the actual value read for that variable by simply adding either offset to the Monitor table in the FSUIPC Logging Tab -- select Normal log in the options below after entering the offset and data type (U8).

 

Maybe this is a specific problem only in P3D? I don't know if it was the same in FSX. Nevertheless it might be worth reporting this problem to Lockheed Martin, on their support forum.

 

Unfortunately there's no other SimConnect variable that would help.
