The GTX™ 330/330D are Mode S, IFR-certified transponders with datalink capability, including local traffic updates. Now, from the comfort of your aircraft, you can receive FAA Traffic Information Services (TIS), including location, direction, altitude, and climb/descent information of nearby aircraft on your GNS 530 or GNS 430. The result is improved communication between aircraft and air traffic control (ATC), providing U.S. pilots with greater traffic awareness in busy terminal areas.

Built on the same receiver and transmitter technology as our best-selling GTX 327, these units' solid-state design increases efficiency by using less power, creating less heat emissions, and eliminating warm-up time. Both units feature an easy-reading DSTN Liquid Crystal Display which reverses the numbers out of black for optimal viewing, an innovative keypad that makes entering a squawk code a snap, and a dedicated VFR button for quick-and-easy VFR squawking. The GTX 330 and 330D also offer several timing and display functions: flight time, count-up and count down timers, and current pressure altitude. Other features include remote ident and auto standby, plus altitude monitor with voice alerting.

The GTX 330D contains all of the features of the GTX 330, and adds antenna diversity for improved visibility to TCAS-equipped aircraft flying above you.
