Trig Avionics transponder gets FAA nod

Trig Avionics has received FAA STC approval of its TT31 transponder with Garmin’s GNS 400W and 500W series of GPS navigators.

Trig’s TT31 transponder is a plug and play retro-fit for the KT76A and KT78A — and it’s also ADS-B Out capable too, according to company officials.

Trig CEO Andy Davis said, “There are many U.S. aircraft that have a Garmin 430W or 530W installed. Our ADS-B STC shows how practical and affordable a compliant ADS-B Out solution can be when matched with our Trig TT31 transponder using version 3.13 software.”

Trig AvionicsPeregrine of Denver is Trig’s STC partner. CEO David Rankin ran the flight test program, conducting the validation of the TT31 transponder and 400W/500W series GPS equipment.

“The install of Trig equipment was very easy,” Rankin said. “The TT31 used the existing aircraft transponder antenna. This is a really attractive retro-fit option. For ADS-B Out we installed a Trig tray, the set up and integration with the 430W WAAS GPS was straight forward. I’m certain this equipment combination will have a broad appeal as pilots want to meet the ADS-B mandate with the minimum expense. Trig’s TT31 matched with an existing 430W or 530W makes compliance totally practical.”

Trig’s STC covers a wide range of aircraft types and for those types not currently listed the FAA allows local Field Approval.

Trig has a dealer network in North America he noted. Trig are also partners with the NextGen GA Fund. This provides customers with access to a comprehensive loan scheme specifically designed to help GA aircraft owners pay for their ADS-B equipment and related install.
