TRIG TT31 Transponder

The TT31 is a highly efficient class leading transponder. It 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 1 Mode S technology that is 1090ES ADS-B Out capable too – to the latest international standard.

It’s easy to use and operate, with a clear bright display and simple user interface. Features include a flight timer, stop watch and altitude monitor (can alert you of a deviation from your selected altitude).

The TT31 is compatible with many popular GPS position sources including Garmin GNS and GTN navigators and the Trig TN70.
