Trig makes the world’s smallest and lightest Mode S certified GA transponders. The TT22 Trig compact transponder can fit into to the tightest panel space. This allows other instrumentation or avionics to be accommodated, providing a genuine benefit in any installation.
The TT22 is a high powered performer, a Class 1 transponder – ideal for use in aircraft flying above 15,000 feet and / or above 175 knots. It is also suitable for ADS-B, where a Class 1 transponder is required (within the U.S. for example). 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 – for further information see our U.S. ADS-B page.
The TT22 is a two part transponder with a compact control head; this includes an inbuilt altitude encoder – saving further space and expense. A separate hardware box can be installed anywhere in the airframe. The mounted control head is only 54mm (2 3/25”) deep and can be fitted in panel using a 57mm (2 ¼”) round hole or smaller compact mount, the unit ships with the necessary fittings for both install options. The TT22 unit is highly efficient and is ideal for use via an auxiliary battery in gliding or lighter than air flight.
The TT22 transponder is easy to operate and with a crisp, bright display. It is easy to read in all lighting conditions and features manual dimming. The higher powered TT22 can be used in IFR and VFR flight in high performance aircraft, over 175 knots and/or above 15,000 feet. The transponder control head is splash proof too so it’s ideal for open cockpit and seaplane operations.
Mode A and C transponders are now being replaced by Mode S technology which is optimised for tomorrow’s airspace requirements. Despite its modest size the TT22 is a heavyweight performer, at 250 watts nominal power output this class 1 transponder meets the latest FAA TSO C166b standards for ADS-B Out.
Trig were the first company in the world to offer a ‘mandate ready’ certified 1090ES ADS-B Out compliant solution. The TT22 is popular in the U.S. where a certified WAAS GPS, and a ground air determination device are also required forming the ideal 2020 ADS-B solution. It’s worth remembering that to receive all ADS-B In transmissions in the U.S. the FAA requires a functioning certified ADS-B Out device, so don’t miss out on airspace information – fit a Trig TT22.
All Trig products come with a two year warranty, supported by our global network of Approved Trig Dealers and Approved Trig Service Centers in the U.S. and Australia.
