GROUND MODE
Ground Mode is normally selected automatically when the aircraft is on the ground. The transponder
powers up in the last mode it was in when shut down. Ground Mode can be overridden by selecting any one
of the Mode Selection Softkeys. A green ‘GND’ indication and transponder code appear in the mode field of
the Transponder Data Box. In Ground Mode, the transponder does not allow Mode A and Mode C replies,
but it does permit acquisition squitter and replies to discretely addressed Mode S interrogations.
When Standby Mode has been selected on the ground, the transponder can be returned to Ground Mode
by selecting the
GND
Softkey.
