Now approved for installation with Rockwell Collins’ latest TDR-94/94D transponder variant.

FreeFlight Systems’s 1203C SBAS/GNSS sensor is now approved for installation with the Rockwell Collins TDR-94/94D transponder. Collins has received FAA approval of an approved model list STC (AML-STC) for ADS-B Out installation across a range of Part 23 Class 3 and 4 aircraft, with additional Part 25 certifications anticipated this year. FreeFlight maintains that the product pairing provides a cost-effective way to meet the upcoming ADS-B mandate in the U.S. and said that foreign validations are planned to support mandates in other regions.
