Tags: Avionics,Transponders & Encoders,Transponders,EACH

SKU: 00772-00


The innovative design of the TT22 saves both space and weight while delivering certified performance. The transponder kit comes in two parts: a compact control head that includes a built-in altitude encoder, and a separate hardware box that can be installed anywhere in the airframe.

Mode S technology provides visibility to ATC, commercial, and military traffic. Trig transponders are ADS-B Out capable, with a suitable GPS – sold separately, meeting the latest FAA certification standard for ADS-B known as TSO-C166b. Pilots of light-sport, experimental, and home-built aircrafts can use the TT22 with Trig’s TN72 (sold separately) GPS Position Source. This combination meets the 2020 ADS-B mandate and is FAR 91.227 compliant.
