STC Connects FreeFlight Sensor and L3 Transponders
The STC provides a pathway to lower-cost ADS-B Out upgrades for a variety of legacy business jets.

Stevens Aviation has received an approved model list (AML) STC for installation of the FreeFlight Systems 1203C SBAS/GNSS sensor along with L3’s NXT mode-S transponders, to provide a reasonably priced ADS-B Out solution for several Part 25 business aircraft. The first installation was done in a Cessna Citation 650 with non-integrated avionics by Stevens Aviation’s Dayton, Ohio avionics team.
