Trig TT31 – Class 1 - Mode S and 1090ES ADS-B Out transponder

Trig’s TT31 transponder is the ideal retro-fit for the popular KT76A, KT76C and KT78A transponders. The TT31 is a Class 1 transponder which will ‘plug and play’ straight into an existing KT76A, KT76C and KT78A tray. This significantly reduces both installation time and cost. It provides pilots with class leading Mode S technology that is also 1090ES ADS-B Out capable too.

The latest upgrade includes TIS traffic enhancements and enables ADS-B Out to be configured using the existing tray. The Trig TT31 is compatible with many popular GPS position sources including Garmin GNS and GTN navigators and the Trig TN70. This makes installation flexibility the best in class. A free FAA STC allows the TT31 to be installed as a compliant ADS-B Out solution in 650 aircraft types.

Trig TT31 Features:

  • Improved retrofit performance – 'plug and play' Mode S installation for KT76A, KT76C and KT78A
  • Certified Mode S and 1090ES ADS-B Out capable
  • Certified for IFR / VFR flight
  • Amongst the lowest power consumption in class
  • 240 watts nominal output
  • TIS traffic capabilities – portable and/or panel mounted avionics
  • Backlit LED display
  • No cavity tube – no warm up time required (no need for dropper resistors)
  • EASA ETSO and FAA TSO Certification – TSO C166b the latest ADS-B standard
  • Free European Minor Change approvals
  • Free FAA ADS-B STC for 650 aircraft types
  • Software provides the widest compatibility with third party avionics
  • Unbeatable value and quality – designed and manufactured in the U.K.
  • Two year worldwide warranty

The Trig 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 TT31 includes data link support for the U.S. TIS traffic service, uplinked from approach radars. TIS traffic can be displayed on a variety of portable and panel mount displays, coverage includes most US terminal areas.

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 transponder of choice, it was the world’s first transponder certified to TSO C166b. This is latest FAA standard for the U.S. 2020 ADS-B mandate and demonstrates Trig’s advanced levels of compliance. 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, fitting a Trig TT31 ensures a full ADS-B In picture.

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.

All Trig products come with a two year warranty, supported by a global network of Approved Trig Dealers and Approved Trig Service Centers.

Trig TT31 Ordering Options:

  • If you are doing a new install, get the complete kit which includes the TT31, the mounting tray, and the connectors.

Swap-in success!

  • By Jackson from Whiteman CA on Tuesday, February 26, 2019
  • Pros: Save big money on install, Future ADSB 2020 compliance, Shows the altitude its broadcasting to ATC
  • Review: It dropped into the slot that our "Intermittant mode C" King transponder was in.

    Took the A&P longer to write up the logbook entry than the whole install, setup and test procedure.

Trig TT31 Mode S XPDER

  • By Richard from Avondale AZ USA on Thursday, April 13, 2017
  • Pros: Plug and play replacement for the KT76A
  • Review: I bought it as a plug and play replacement for my aging KT76A, and it is exactly as advertised. However, if you buy the install kit it can be much more and satisfy the ADS-B Out requirement when paired with a WAAS GPS. I already had a UAT for ADS-B so I opted for a drop in KT76A replacement, but it is nice to know I have the flexibility to add 1090 MHz ADS-B with a simple wiring chassis and new mounting tray.

2 QUESTIONS & ANSWERS

  • Previously Asked Questions

  • Tuesday, October 01, 2019

    Q: How do I connect this to my Garmin GNS430W? Also, I do not have a KT78A, how do I make this install if I have a different previous transponder?

    A:


    You will need to purchase the Trig TT31 with the complete installation kit (Option#1 for the New Install Kit) for the cables to connect to the Garmin GNS430W. This is the same for any of the approved Garmin GPS units that will work as your ADS-B In unit.
    And if you do not have a previous transponder which will allow the TT31 to ‘plug and play’ straight into an existing KT76A, KT76C and KT78A tray, don't worry, you will just need to get the New Install Complete Kit witch will come with a new tray to install to your panel.

    Q: Can the TT31 handle call signs other than N number? For example Angel Flight?

    A: You can change the TT31 call sign during normal operations. To do this press the FLT/SQ button to show the N number then use the right-hand knob to change the first letter. Press enter to confirm the changed letter which will move the cursor onto the next letter. The call sign can be up to 8 characters long. Once the desired call sign has been input enter a blank space character to confirm. Please note this has no effect on the Mode S address which remains constant as per regulations.  This can be found in the operating handbook here: https://www.trig-avionics.com/library/00454-00%20AF%20TT31%20Operating%20Handbook.pdf
