STC Program (EASA)

European pilots who operate EASA type approved aircraft can now upgrade their TT31 or TT22 Mode S transponder to be ADS-B Out capable, using popular Garmin GNS and GTN WAAS Navigators. Other suitable GPS units can also be used, including Trig’s TN70 GPS position source.

Our free EASA STC and ADS-B STC AML (approved model list) is available via Approved Trig Dealers. It enables numerous aircraft to be legally configured using either a Trig TT31 or TT22 transponder, with listed GPS units.

This is a practical and cost effective way to become ADS-B Out equipped, enhancing your visibility and flight safety.

The following WAAS GPS units are compatible and approved for use with TT31 and TT22 transponders.

  • Garmin GTN 600 and 700 series
  • Garmin GNS 400W and 500W series
  • Trig TN70 WAAS GPS
  • FreeFlight 1201 WAAS GPS
  • Accord NexNav Mini WAAS GPS

Please note – our TN72 GPS Position Source can be used for voluntary equipage of ADS-B. In Europe the installation of a TN72 in an EASA aircraft uses our free EASA Minor Change, an AML (approved model list).
