Trig streamlines ADS-B Out compliance

Existing GPS, tray reduce installation cost

Trig Avionics has launched a faster, more cost-effective path to Automatic Dependent Surveillance-Broadcast (ADS-B) Out compliance based on its TT31 Mode S Extended Squitter ADS-B Out transponder that the company calls Express Lane service.

With the right avionics, Trig Express Lane dealers can now install a 2020-compliant solution in as few as five to eight hours, which Trig says is three times faster than installations for many competitors’ equipment. The company’s Express Lane webpage allows aircraft owners to check aircraft configuration and locate a participating Trig dealer.

“Aircraft owners often overlook the expense of fitting ADS-B,” said Andy Davis, Trig CEO. “If you have an old [Bendix King] KT 76A, KT 76C, or KT 78A transponder, then a TT31 is a simple slide-in replacement. If you also have an existing [Garmin] GTN or GNS WAAS navigator, then you qualify as an Express Lane candidate. Trig provides the most compelling and quick upgrade path.”

If the aircraft doesn’t have an installed navigator that can provide the required ADS-B Out position source, Trig’s certified TN70 WAAS GPS receiver is an ideal option, the company noted.

New software for the Trig TT31 transponder—version 3.17—includes new features that make the streamlined installation possible, the company said. “Our research across general aviation indicates that Trig’s improved TT31 installation is quicker and easier than competitor products,” said Dave Rankin CEO of Peregrine, Trig’s STC partner. “Customers with legacy avionics will genuinely benefit by saving time and money.”

Using the existing transponder antenna, encoder, wiring, and compatible Bendix King tray for the new TT31 takes the complexity out of the installation, Trig said, adding that the TT31’s list price of $2,995 provides aircraft owners with the best combination of features, quality, and value.

The biggest benefit from the software update is the fact that an airspeed switch is no longer required when installing a TT31 in a fixed-gear aircraft, said Jon Roper, Trig’s marketing manager. The transponder now makes the air/ground determination electronically in aircraft that do not have a squat switch, eliminating the need to install an inexpensive airspeed switch that increased installation cost and complexity. A conservative estimate for installing a TT31 through the Quick Lane program is five to eight hours of labor, Roper said.

Using the existing transponder antenna, encoder, wiring, and compatible Bendix King tray for the new TT31 also help to simplify the installation, Trig said, adding that the TT31’s list price of $2,995 provides aircraft owners with the best combination of features, quality, and value.

Trig’s Express Lane includes a free supplemental type certificate and associated approved model list that includes more than 650 aircraft models. Participating dealers will be added to the Trig Express Lane webpage as the initiative rolls out, the company noted.
