ALTITUDE MODE
ALT Mode can be selected at any time by pressing the
ALT
Softkey. When ALT mode is selected,
an ALT indication will appear in the mode field of the Transponder Data Box. Selecting ALT mode enables
transmission of transponder replies and squitters. Transmissions will include pressure altitude information.
The ALT indication and transponder code in the Transponder Data Box will appear green while airborne and
white while on the ground. When the transponder is operating with an air state of on-ground it will disable
replies to Mode A, Mode C, and Mode S all-call interrogations so the aircraft will not show up on the traffic
systems of other aircraft.

reply status field of the Transponder Data Box.
