The panel-mounted GTX 327 is a TSO-certified Mode C digital transponder. Its innovative features, proven performance and reliability bring a whole new level of transponder utility to your aircraft. Looking for a more affordable alternative? The panel-mounted GTX 320A Mode C transponder features a pilot-friendly design minus the DSTN LCD display.

Enjoy Innovative Features

GTX 327 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 200 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 330 Mode S transponder, the 327 also offers several timing and display functions, including flight time, count-up and count-down timers, as well as current pressure altitude.

GTX-327 Product Commentary

Sarasota Avionics The GTX327 is a mode A/C capable digital display transponder. The Garmin GTX327 has proven to be one of the more reliable transponders in the field today due to its solid state design. After the GTX327 transponder is installed our customers/pilots report that their favorite feature is the ability to simply push 4 buttons to quickly enter an ATC squawk code. Gone are the days of turning knobs and hoping you don't forget the assigned code by the time you get to the fourth digit. A built in count up or count down timer is also a pilot operation friendly feature that can be used as a reminder to switch fuel tanks, check weather, or whatever the pilot chooses. The GTX327 is a recommended upgrade for any pilot flying a plane with an old school knob style selection transponder.
