GARMIN GTX 330 MODE S TRANSPONDER
General –
The GTX 330 Mode S Transponder is located in the lower portion of the radio rack
panel assembly. The GTX 330 is a radio transmitter and receiver that operates on radar
frequencies, receiving ground radar or TCAS interrogations at 1030 MHz and transmitting a
coded response of pulses to ground-based radar on a frequency of 1090 MHz. The GTX 330 is
equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for
18 seconds. A picture of the transponder is shown in Figure 7 - 50.
In addition to displaying the code, reply symbol, and mode of operation, the GTX 330 screen
will display pressure altitude, density altitude, temperature, and timer functions, depending on
equipment connections and configuration selection. The unit also features an altitude monitor,
Traffic Information Service (TIS) traffic advisories and flight timers. The TIS feature provides a
visual display (on a separate display unit such as the Garmin GNS 430 unit) of intruder aircraft
within a specified altitude and distance. A voice or tone audio output announces altitude
deviation, TIS traffic advisory, and Count Down timer expiration.
