Surveillance for Busy Airspace

• IFR-certified 250 W transponder
• Optional 1090 MHz ES broadcast technology
• Easy-to-read LCD display
• Traffic Information System (TIS-A) alerts on compatible displays
• Pressure altitude, dedicated VFR squawk button and more

A panel-mounted Mode S digital transponder series with traffic datalink capability and dedicated pushbutton keys for squawk code selection, the GTX 330 family brings ATC aircraft surveillance to new levels of precision, reliability and performance.

Leading the Way to ADS-B with Optional ES Upgrade

Optionally available with available ES, or Extended Squitter, technology the GTX 330 takes the lead in providing an affordable pathway to ADS-B compliance for the Next Generation airspace system. Using precise GPS-referenced positioning information, the extended squitter technology enables transponders to automatically transmit more accurate, and more useful, traffic surveillance data — including aircraft flight ID, position, altitude, velocity, climb/descent, and heading information (compared to traditional Mode S and Mode C transponders, which can only broadcast altitude, and thus require ground-based radar to correlate and identify the aircraft's position).
