Q

REMEMBER ATC TRANSPONDER
DIFFERENT MODES!!!

A

MODE A – Transponder transmits an aircraft identification code which is a four-digit number

MODE C – Transponder transmits the barometric altitude of the aircraft, which it receives from the ADC (Air Data Computer)

MODE S – Transponder sends individual messages in reply to selective interrogations from the ATC ground station and from other aircraft
