Rockwell Collins Earns Part 25 ADS-B Out AML-STC
The announcement follows the company's Part 23 AML-STC approval earlier this year.

Rockwell Collins has received FAA certification for its ADS-B Out Part 25 approved model list supplemental type certificate (AML-STC). It covers multiple aircraft models from Bombardier, Gulfstream, Textron, and Sabreliner. The solution pairs the company’s TDR-94/94D mode-S transponder variant with either its GPS-4000S global positioning sensor or a Freeflight Systems 1203C SBAS/GNSS position source. It also supports Applied Avionics’s Vivisun ADS-B Fail annunciators with integrated Arinc 429 discrete signal converter, which responds directly to the Arinc 429 data bus and provides a “fail” indication to the pilot, eliminating the need for any additional hardware. According to Rockwell Collins, this latest transponder improvement automatically generates a fixed flight ID from the mode-S code for U.S.-registered aircraft.
