Additional items you will require, but which are not in the TT31 package, include:
-Antenna and fixing hardware. The TT31 is compatible with any transponder antenna approved to (E)TSO C74 or C112.
-Altitude encoder. You require an encoding altimeter or a blind encoder with either parallel Gray code or RS232 serial output. For best results, and simpler installation, an encoder with a serial output is recommended.
-Cables. You need to supply and fabricate all required cables.
-Fixings. To secure the transponder tray to the airframe you will need at least 6 flat head screws and six self-locking nuts. If the aircraft does not have existing mounting provisions.


The TT31 transponder is an ED-73B Class 1 compliant Mode S level 2 datalink transponder, with support for extended squitter. It meets all the requirements for non-diversity Mode S elementary surveillance transponders in Europe for both IFR and VFR flight.

The TT31 also supports 1090 MHz Automatic Dependent Surveillance Broadcast (ADS-B) extended squitter. By linking the TT31 to your existing GPS receiver, the TT31 can transmit position information to appropriately equipped ground stations and other aircraft. The TT31 will also be field upgradeable to support Traffic Information Service (TIS) functions, where available, by interfacing to an appropriate cockpit display.

The TT31 is designed to be compatible with 14 and 28 volt systems without special configuration, and is compatible with serial and parallel altitude encoders.
