Trig TT31

If you are looking for an inexpensive and power-efficient Mode S transponder then Trig’s TT31 will certainly suit your needs. This affordable unit meets all European elementary surveillance requirements and is TSO approved for fitting to both European and FAA registered aircraft.

With a backlit LCD Display, altitude monitor, timer/stopwatch functionality and more, the TT31 is a feature packed transponder. Easy to use rotary knobs also help to make operation incredibly intuitive.

Trig’s TT31 features a plug and play installation so, although Mode S transponder upgrades must be carried out by a licensed engineer with an EASA approved Minor Change, the downtime and cost for installation is minimalised. As the TT31 fits into the same mounting tray as the KT76A transponder this is an ideal choice whether you’re upgrading or installing new. Contact RGV now for additional information.
