Trig Avionics has upgraded its TT31 transponder, which previously required a tray change when installing ADS-B. Using software version 3.11 or higher, installers can now use the original installed tray, reducing the time and cost of a compliant ADS-B install, company officials noted.
Existing TT31 owners can also benefit with a software upgrade via their Trig dealer, officials added.
Peregrine of Denver is Trig’s STC partner. Officials there report they have seen a growing number of aircraft owners using Trig’s interface with Garmin 400 and 500 series GPS navigators. Other GPS solutions are also available, including Trig’s TN70 kit. This is designed as a retro-fit for non-compliant aircraft and includes a WAAS GPS unit and antenna.
Trig is also a partner with the NextGen GA Fund, which provides loans to GA pilots to fund the purchase and installation of equipment to meet the ADS-B mandate.
