Trig Avionics was founded in 2004 and set out to produce a solid state and energy efficient Mode S transponder. A new generation of transponders were required to meet a European wide mandate for Mode S. At the time aircraft owners had few options available, so Andy Davis and his team changed this. The resulting TT31 transponder set a new benchmark in quality, capability and value. Today Trig manufactures a wide range of avionics for General Aviation. Pilots and aircraft owners worldwide fly with the class leading VHF radios, transponders and ADS-B technology.
