Enjoy Innovative Design

GTX 330 features a solid-state design, and with no warm up time, lower power consumption and much lower heat emissions, you’ll enjoy a longer service life. It provides 250 watts nominal power output and has an easy-to-read 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 VFR squawking. Similar to the GTX 327 Mode C transponder, the 330 also offers several timing and display functions including flight time, count-up and count-down timers and current pressure altitude. In addition, it comes with remote ident and auto standby, plus an altitude monitor with voice alerts.
