Trig Avionics Speeds Up ADS-B Installs

Trig Avionics unveiled its ADS-B Express Lane Service at the Aircraft Electronics Association conference. Express Lane is designed to lower ADS-B Out installation costs for aircraft already equipped with the necessary GPS sensor and transponder hardware.

“Aircraft owners often overlook the expense of fitting ADS-B,” said Trig CEO Andy Davis. An Express Lane ADS-B Out upgrade can be installed in five to eight hours. The company was able to speed up installation time by improving the software in the Trig TT31 transponder.

The optimal setup for an Express Lane upgrade is an existing BendixKing KT76A, KT76C, or KT78A transponder and a WAAS GPS sensor such as a Garmin GTN or GNS navigator. In this case, the installer would swap out the BendixKing transponder with a Trig TT31 mode-S transponder, which fits into the original tray and uses the existing antenna, encoder, and wiring.

The $2,995 TT31 is approved under an approved model list STC for installation in more than 650 aircraft, including some turboprop models.
