On the A330 and 777 the flight number is put into the FM/FMC * during the setup preflight.
Input is in the usual XXX123 format.
We must put it in correctly as it won't logon to CPDLC if it's wrong ( been there and done that!! )
So ask them to confirm their ident is correctly entered on their FM/FMC
The Transponder has the code given to us by you. The ADS B out function transmits all the data ( pre programed and some stuff from the FMC I think ) free to air from the transponder, we don't have any means to input data into the transponder apart from the discrete code.
* FM Airbus speak for Flight Management
* FMC Boeing speak for Flight Management Computer.
Basically the same thing.
