following Modes are possible apart from Standby:
•
A C –
„Mode A+C“
Transponder replies only on Mode A and Mode C interrogations.
•
A – –
„Mode A“
Transponder replies only on Mode A interrogations.
In STBY (Standby) mode, all transponder transmissions
are disabled completely! Therefore, the transponder is not

Never use the STBY mode in flight unless you are requested
to do so by air traffic control. Always remember to put the
transponder in active mode prior to take off!
