While providing the usual identification code and pressure altitude

information as Mode A and C transponders, the Mode S transponder

also uses a unique aircraft address to enhance the tracking

capabilities of ATC and other Mode S transponder-equipped aircraft.

The interrogations that ground-based surveillance radar transmit

include the identification information of the target airplane ensuring

that when other aircraft receive the interrogation, they will not respond.

Digitized altitude information is provided by the altitude digitizer

(encoder) plumbed into the airplane static system. The transponder

and integrated controls are mounted in the center console. The

transponder control provides active code display, code selection,

IDENT button, and test functions. The display is daylight readable and

is automatically dimmed through a photocell. The controller buttons

are dimmed through the INST lights control on the instrument panel

bolster. The transponder antenna is mounted on the underside of the

fuselage just aft of the firewall. 28 VDC for transponder operation is

controlled through the Avionics Master Switch on the bolster switch

panel. 28 VDC for receiver, transmitter, and altitude encoder operation

is supplied through the 2-amp ENCODER/XPONDER circuit breaker

on the Avionics Non-Essential.

Reply Light

The reply light is the small reverse video "R" immediately below the

mode annunciation in the display window. The reply light will blink

each time the transponder replies to ground interrogations. The light

will remain on during the 18-second IDENT time interval.

Mode Selector Keys

The mode selector keys are located in a circular arrangement

immediately to the left of the display window. The selected mode is

annunciated at the left side of the display immediately adjacent to the

selector keys. The four positions are:

OFF - Turns off all power to the GTX 330 transponder. The

transponder should be off until the engine is started. Normally, the

transponder can be left in the STBY position and allow the Avionics

Power Switch to control system power.

STBY - Powers the transponder in standby mode. The last active

identification code will be selected. In STBY, the transponder will not
