TT31 – Class 1 - Mode S and 1090ES ADS-B Out transponder

Trig’s TT31 transponder is the ideal retro-fit for the popular KT76A, KT76C and KT78A transponders. The TT31 is a Class 1 transponder which will ‘plug and play’ straight into an existing KT76A, KT76C and KT78A tray. This significantly reduces both installation time and cost. It provides pilots with class leading Mode S technology that is also 1090ES ADS-B Out capable too.

Our latest upgrade includes TIS traffic enhancements and enables ADS-B Out to be configured using the existing tray. The TT31 is compatible with many popular GPS position sources including Garmin GNS and GTN navigators and the Trig TN70. This makes installation flexibility the best in class. A free FAA STC allows the TT31 to be installed as a compliant ADS-B Out solution in 650 aircraft types for further information see our U.S. ADS-B page.
