One year later & our ADS-B STC has been performed all over the U.S. by Garmin Dealers for $40-$50k INSTALLED!

Southeast Aerospace teamed up with Garmin International, Gables Engineering, and Peregrine Avionics to bring the most cost-effective and flexible ADS-B solution to the business aviation community.

Southeast Aerospace’s Part 25 AML STC# ST00835DE is available for non-TCAS II. The prototype installation was performed on a Cessna Citation III. FAA conformity has been completed along with the Ground and Flight Test. Operators will have the option to receive ADS-B In on their portable devices and/or existing Garmin displays (additional approvals may be required for the ADS-B In display). Estimated price of the system installed is UNDER $50,000 at your local Garmin dealer.

This is all possible through the installation of dual Garmin GTX-3X5Rs and the Gables G7534-100X control head. The Gables control head can be installed to replace the aircraft’s existing transponder control and provide full transponder control of both GTX-3X5Rs. The installation of an ADS-B fail annunciation to the panel will be required by the STC. The use of the GTX-3X5R’s internal GPS or a Garmin GNS/GTN unit panel mounted GPS will meet the positioning requirements of AC-20-165B.

Now DGAC Approved!
