FAA grants CMC Electronics approval for ADS-B Out compliance solutions
The U.S. Federal Aviation Administration (FAA) has approved two Supplemental Type Certificates (STCs) for CMC Electronics, to help airplanes comply with automatic dependent surveillance-broadcast out (ADS-B Out) requirements.
Boeing 737 Next-Generation Aircraft
The FAA has approved an STC to install the SBAS-capable CMA-5024 GPS on Boeing 737 Next-Generation aircraft to comply with worldwide ADS-B Out mandates as well as SBAS/GPS navigation enabling the first localizer performance with vertical guidance (LPV) approaches for B737NGs.
CMC’s solution, developed in collaboration with the FAA’s Navigation Programs office, offers operators the advantage of a cost-effective alternative to replacing their current multi-mode receiver (MMR).
The CMA-5024 is an approved DO-260B ADS-B Out positioning source that may be paired with any DO-260B compliant transponder, allowing operators to meet FAA and EASA ADS-B Out requirements, the UAE’s ADS-B Out and RNP requirements mandated by GCAA as well as India’s GAGAN requirements.
The CMA-5024 is the only solution available that is approved to introduce LPV on B737NG aircraft. With the CMA-5024, the B737NG aircraft can take advantage of satellite-based augmentation system (SBAS) navigation throughout all phases of flight.
An LPV approach is the highest precision GPS instrument approach available not requiring specialized crew training. It aims to reduce costs associated with flight delays or cancellations and provides airlines with a safe approach into airports when ILS is unavailable.
The CMA-5024 meets the requirements for an IFR civil certified GNSS and is compatible with all SBAS systems operating around the world such as WAAS, EGNOS, GAGAN and MSAS. SBAS augments GPS to provide an extremely accurate navigation solution throughout all phases of flight, from departure to en-route, through LPV CAT-l equivalent approach. The CMA-5024 complies with published Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) navigational mandates.
EASA approval of the STC is in progress. Future growth to GBAS GLS precision approach capability can be obtained by upgrading to CMC’s new CMA-6024 GPS/SBAS/GBAS receiver system.
For Business Jets
CMC Electronics and DAC International received an FAA STC (ST00934DE) for aircraft equipped with Honeywell’s Primus II avionics suite.
The 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.
