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.
My guess is, contrary to avionics shops warnings, new products will drive down costs until 2019 when the inevitable rush to comply will drive prices back up. Post 2020 they’ll fall again. My 2¢
Sub-$3k is better. Progress is being made. I think these vendors are going to need to get down closer to $1k, or $1500 installed before this becomes affordable and rational for people flying sub-$40k airplanes. They also need to start incorporating display or access to the data for these lower prices to make it appealing to the owner. You still have to spend quite a bit more to get an ADS-B solution that also feeds into your visual nav systems (whether that be an EFB or panel-mounted moving map GPS). There’s an awful lot of C172s and Cherokees that it just makes little economic sense to drop thousands on an electronic doodad, especially when you have to spend thousands more before that doodad provides actionable data to the pilot.
