GARMIN GTX 330 “S” Mode Transponder
(With Mounting Tray – Installation Harness required)

Delivery £25.00 if required

The GTX 330 is designed to meet the European Mode-S transponder mandate.

This full featured TSO certified transponder brings a unique level of functionality and utility to an aeroplane. The solid state transmitter provides 250 watts nominal power output and eliminates the need for a cavity tube which, sooner or later, will fail and require expensive replacement. And since the transponder’s design is 100% solid state, there’s no warm up time, lower power consumption and much lower heat emission. All of which translates to a longer service life.

Some of the GTX 330 biggest features are the easiest to see. Among them, the easy reading DSTN Liquid Crystal Display which reverses the numbers out of black for optimal viewing. An innovative keypad makes entering a squawk code a snap. And a dedicated VFR button allows for quick and easy 7000/VFR squawking.

The GTX330 also offers several timing and display functions: flight time, count-up timer, count-down timer, or current pressure altitude. Other features include remote ident and auto standby.
