The TT31 – low power, high performance.
The transponder has a bright and easy to read backlit display, operation is simple via a conventional rotary knob enabling rapid
selection of Squawk code and Flight ID. The TT31 comes with additional features that include a stop watch, flight timer and altitude alarm.
The TT31 has the lowest power consumption in its class (half that of most legacy transponders), it needs no warm up time and is ready to work as soon as you strap in.
The reliability of an aircraft’s avionics can be adversely affected by excessive heat.
The TT31’s low power consumption produces less heat in your avionics stack and significantly reduces loading on your aircraft’s electrical system.
This efficiency has no impact on performance; as a consequence fitting a TT31 actually enhances the reliability of your entire avionics system.
The TT31 is a great new or retro-fit solution; it operates at 240 watts from a supply voltage of either 14 or 28 volts. Installation
is straight forward without any special configuration or dropper resistors. The TT31 can use either a parallel or serial altitude encoder, and
can even act as a serializer for your GPS baro-aiding input.
The TT31 conventional panel mount transponder – the class leader
Class leading performance with the easiest transponder upgrade path for legacy units.
Trig Mode S transponders provide air traffic control with accurate position data. This makes negotiation of
controlled airspace more certain and can significantly reduce the amount of communication required with ground based controllers.
Fitting a Trig Mode S transponder increases your visibility to other airspace users, enhancing flight safety.
Trig offer free EASA minor changes paperwork for most popular single engine aircraft - saving you time and money.Additional Features
The TT31 is a highly efficient class leading transponder. It’s easy to use and operate, with a clear bright display and simple user interface.
Features include a flight timer, stop watch and altitude monitor (can alert you of a deviation from your selected altitude).
The latest performance upgrades are available during the life of your product via Trig software upgrades, avoiding the need for expensive hardware upgrades.
MODE – S AND ADS-B
Mode A and C transponders are now being replaced by Mode S transponders, this technology is optimised for tomorrow’s airspace requirements.
The introduction of ADS-B surveillance technology means the modern transponder has now become the hub of future airspace compliance requirements.
Here the TT31 remains the class leader, it was the world’s first transponder certified to TSO-C166b. This demonstrates Trig’s advanced levels of compliance.
It’s worth remembering that to receive all ADS-B In traffic transmissions in the U.S. the FAA requires a functioning certified ADS-B Out device.
The TT31 uses half the electrical power of legacy transponders, whilst still transmitting at a higher signal power, its efficient design reduces waste heat in the avionics stack.
This reduces the load on the aircraft electrical system improving overall reliability. The flexible power input means that both 14 and 28 volt systems can be used without special configuration or dropper resistors
(we recommend that any dropper resistor fitted for a previous transponder should always be removed). The TT31 is compatible with both parallel and serial altitude encoders;
it can even act as a serial altitude repeater to provide a convenient altitude source for your GPS.
