Global Expands their ADS-B Out Solutions with FreeFlight Systems

IRVING, TEXAS, 24-February 2021 – Global Aerospace Design Corporation (Global), a technical services organization dedicated to meeting all aircraft certification efforts, announced today that they have successfully added three aircraft types to Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) ST04299CH for Automatic Dependent Surveillance-Broadcast (ADS-B) Out. This recent amendment includes FreeFlight Systems 1203C Global Navigation Satellite System (GNSS), a satellite-based augmentation system, as the primary position source.

Initially, this STC covered the installation of ADS-B Out utilizing ACSS XS-950 Mode S Transponders with Rockwell Collins GLU-920/-925 Multi-Mode Receivers as the position source. However, the most recent amendment adds three aircraft types, the Boeing 737-400, Boeing 737-500, and Airbus A310-300, utilizing the FreeFlight 1203C receiver. “FreeFlight Systems works closely with operators to develop high integrity, high-reliability systems that will provide the best NextGen support for the commercial airline industry,” explained Tim Taylor, president and CEO of FreeFlight Systems. “The advantages of this system is that it will allow these aircraft to fly more efficiently and ultimately improve situational awareness and safety.”

FreeFlight’s 1203C receiver is specifically designed to provide highly accurate global positioning of an aircraft for airline transport, military, and business aviation platforms. The 1203C is certified to TSO-C145c and meets position source requirements for Required Navigation Performance (RNP) and other L-NAV operations. Its system allows operators to integrate NextGen avionics and leverage advanced safety and greater fuel efficiencies within their aircraft fleet.

“Global proudly continues to expand our ADS-B Out Solution offerings in support of our customers,” stated Todd Hamblin, President and CEO of Global. “In conjunction with FreeFlgiht, we are not only happy to cover more aircraft but to provide an alternative solution as well.”

All aircraft flying in U.S. domestic airspace as of December 31, 2019, must be equipped with ADS-B Out. However, the amended European Mandate grants extensions until June 07, 2023, and exemptions in some cases. Learn more about the amendment here.

Currently, Global is the owner of two ADS-B Out Supplemental Type Certificates.
