Trig TT31 - The ADS-B capable Mode S Transponder that saves installation time and money.
The TT31 is now STC'd for interface with Garmin GNS400W & GNS500W series navigators for full ADS-B compliance.
The Trig TT31 transponder is the perfect retrofit unit for the popular Bendix King KT76A and KT78A transponders. The TT31 is a certified Class 1 transponder that will ‘plug and play’ straight into the existing Bendix King tray, significantly reducing both installation time and cost. It provides pilots with class-leading Mode S technology that is also 1090ES ADS-B Out capable, too – to the latest international standard.
This complete kit includes the TT31 Mode S stack transponder, mounting tray, connector kit, and installation & user manuals.

Trig TT31 1090ES ADS-B Out Transponder
Replacing your old transponder or updating your aircraft avionics? If so, the TT31 should be your conventional panel mount transponder of choice. Fixed-wing and rotary pilots around the world have selected the TT31 for its superior features, great value, and superb support.
The TT31 is the easiest upgrade to the popular KT76A, KT76C and KT78A, with plug and play Mode S capability – this transponder gets to work straight out of the box.
2020 ADS-B Compliance
As a fully capable 1090 MHz Extended Squitter ADS-B Out transponder, the TT31 is TSO approved by the FAA to C166b. This makes the TT31 compliant with the latest ADS-B requirements and ensures that it is fit for the future.
The TT31 is compatible with many popular GPS position sources including Garmin GNS 400W / 500W series navigators and the Trig TN70. This makes installation flexibility the best in class.
The TT31 also provides data link support for TIS traffic. Connecting a suitable panel or remote display will show the position of local and conflicting aircraft traffic – this information is sent from TIS ground stations (where available).
Trig TT31 – Low Power, High Performance
The transponder has a bright and easy to read backlit display. Operation is simple via a conventional rotary knob, enabling rapid selection of Squawk code and Flight ID. The TT31 comes with additional features that include a stop watch, flight timer, and altitude alarm.
The TT31 is truly efficient using half the power of most legacy transponders. It needs no warm up time and is ready to work as soon as you strap in. The reliability of aircraft avionics can be adversely affected by excessive heat, the TT31’s low power consumption produces less heat in your avionics stack and significantly reduces loading on your aircraft’s electrical system. This efficiency has no impact on performance; as a consequence fitting a TT31 actually enhances the reliability of your entire avionics system.
The TT31 is a great new or retro-fit solution; it operates at 240 watts from either a supply voltage of 14 or 28 volts. Installation is straightforward without any special configuration or dropper resistors.
The TT31 can use either a parallel or serial altitude encoder and can even act as a serializer for your GPS baro-aiding input.
