The TT22 is a compact two-part Mode S transponder system that meets the FAA’s requirements for an ADS-B Out compliant solution when paired with a certified WAAS GPS. The control head has an integrated altitude encoder, which saves additional space and weight. Fitting in the tightest of panel space, the separate hardware box can be installed anywhere in the airframe. With a 250 watt power output, the TT22 is a classified Class 1 transponder* and can be used in any light sport and GA aircraft operating above 15,000 feet at speeds greater than 175 knots. It features simple operation and a clear and bright display, with manual dimming, which makes it easy to read in all lighting conditions. The control head is splash proof — a perfect fit for use in open cockpit and seaplane operations.
A free FAA STC allows the TT22 to be installed as a compliant ADS-B Out solution in 576 aircraft types. The TT22 is compatible with many popular GPS position sources including Garmin GNS and GTN navigators and the Trig TN70.
The TT22 complete kit (00772-00) includes the TC20 control head, transponder unit and tray, install kit, installation and user manuals, and an EASA Form 1.
