Trig Avionics has achieved a further expansion of its FAA ADS-B STC program for its TT22 transponder.
Trig’s STC, which is free for existing and new customers, covers 576 aircraft types and allows a range of compliant GPS devices to be used, including popular Garmin GNS and GTN navigators.
“This STC is great news for pilots who want to get ADS-B equipped with the minimum fuss and expense,” said Trig Marketing Manager Jon Roper. “The TT22 is a certified device, easy to install and operate and now boasts compatibility with a range of GPS navigators.”
Pilot can use their existing WAAS GPS. If no suitable WAAS device exists, then customers can add a discrete blind Trig TN70 GPS unit, he said, noting this requires no change to the aircraft panel.
The TT22 transponder Control Head has a built-in altitude encoder and uses the existing aircraft antenna. The transponder is a Class 1 device using 1090 MHz, the international standard for ADS-B, increasing operational flexibility allowing use world-wide.
The TT22 has a list price of $ 2,875.
