(Dubai Air Show, November 17, 2019) CMC Electronics and DAC International are pleased to announce the FAA approval of their latest automatic dependent surveillance-broadcast (ADS-B) Out Supplemental Type Certificate (ST00934DE) for aircraft equipped with Honeywell’s Primus II avionics suite.

This new STC provides a low-cost alternative to upgrading the existing onboard Honeywell equipment while meeting the DO-260B ADS-B Out worldwide mandate. This is achieved by replacing the existing non-compliant Primus II transponder with the Becker BXT6553 Diversity Transponder, paired with CMC Electronics’ CMA-3024 GPS/SBAS (GNSSU) receiver.

The STC extends the operating life of a broad range of aircraft such as Bombardier’s Challenger 600 series, Hawker 800/800XP, Learjet 45, Gulfstream G-IV and GIV-X, Cessna Citation II and V, and many more. This is the latest addition to already existing STCs (ST03424CH and ST04159CH), which pair CMC’s CMA-3024 with the Rockwell Collins TDR-94/94D or Honeywell RCZ-8XX Primus II Com/Transponder to meet the DO-260B ADS-B Out standards mandated by the UAE’s GCAA, FAA and EASA for 2020.

Claude Chidiac, Vice President, Sales and Marketing, at CMC Electronics said: “These STCs bring together the best that CMC and DAC have to offer to economically support business jet operators. They combine the respective technological strengths of both companies, namely the most advanced GPS receiver with DAC’s worldwide distribution channels and FAA approved kits. Our joint ADS-B Out solutions deliver high integrity and the cost-effectiveness that business aviation has been waiting for.”

The CMA-3024 aviation sensor provides fully ADS-B compliant SBAS/GPS primary means navigation for business, regional, commercial air transport and helicopter aircraft. It is fully compatible and operational with all SBAS signals worldwide. With SBAS coverage, differential corrections are incorporated to further improve RNP capability, providing RNP0.1 with outstanding navigation system availability.

Full installation kits, including the CMA-3024 and STC package, are provided by DAC International. Please contact DAC for additional information and the complete list of applicable aircraft.
