The Trig TT31 is an ADS-B “In” and ADS-B “Out” transponder.


The TT31 manufactured by Trig is a Mode S, ADS-B “In” and ADS-B “Out” transponder that is IFR and VFR certified.  It comes with an integrated altitude encoder and functions at a 1090 Extended Squitter MHz frequency.  Enjoy subscription-free Traffic service uplinked from approach radars.  TIS traffic can be displayed on portable and panel mounts displays.

This unit is easy to operate and has a clear, bright, backlit LED display.  This makes it easy to read in all lighting conditions and also features manual dimming. The transponder control head is splash proof.  This creates an ideal solution for open cockpit and seaplane aircraft.  Other features include a flight timer, stop watch and altitude monitor.

Trig’s TT31 is compatible with many popular GPS position sources including Garmin GNS and GTN navigators and the Trig TN70, and it is the ideal retro-fit for the popular KT76A, KT76C and KT78A transponders.
