SEA Distributor for Trig Avionics

Southeast Aerospace (SEA) has been appointed the main US distributor for the Trig Avionics TT21 and TT31 transponders. Already a known and widely used transponder in Europe, the TT31 provides key features such as:
Solid-state 240-watt transmitter
European Mode S compliance
Backlit LCD Display
Timer and Altitude Monitor functions

Perhaps the most attractive feature of the TT31 transponder is its direct compatibility with the Bendix/King line of transponders. The TT31 will directly replace the KT-76A, KT-78A and KT-76C transponders with no installation changes. The soon to be released TT21 offers a very compact remote mount Mode S transponder solution with a total weight just over a pound. The TT21 (forthcoming) and TT31 are TSO approved for installation in European and FAA registered aircraft.
