Trig makes the world’s smallest and lightest certified GA transponders. The TT22 Trig compact transponder can fit into the tightest panel space. This allows GA, light sport and glider pilots to fit other instrumentation or displays that otherwise might not have been possible.
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 control head can be installed in the panel either as a 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.
Mode A and C transponders are now being replaced by Mode S. This technology is more advanced and also optimized 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 was the first company in the world to offer a ‘mandate ready’ certified 1090ES ADS-B Out compliant solution. With a certified WAAS GPS and a ground air determination device the TT22 forms the ideal hub of your future 2020 ADS-B solution today.
In fact it’s worth remembering that to receive all ADS-B In transmissions the FAA requires a functioning certified ADS-B Out device, so don’t miss out on airspace information by not fitting a Trig unit. The TT22 can be used in IFR and VFR flight in high performance aircraft, over 175 knots and/or above 18,000 feet.
The TT22 transponder is easy to operate and with a crisp, bright display it is also easy to read in all lighting conditions. The transponder control head is splash proof too so it’s ideal for open cockpit and seaplane operations.
