CMC introduces CMA-6024 GNSS for helicopters

March 16, 2017  - By

Esterline CMC Electronics showcased advanced displays and CMC Electronics-brand integrated helicopter avionics at the Hai Heli-Expo, held Feb. 26-March 1 in Las Vegas.

Esterline’s new helicopter demonstrator featured the CMA-6024 GNSS landing system. While introduced last fall, the CMA-6024 has been customized for rotorcraft operations to allow operators to achieve precision approaches to CAT II and CAT III minimums at helipads.

“Our CMA-6024 is the result of over 35 years of experience in the design and manufacture of certified airborne GPS products for the air transport, business aviation and helicopter markets,” said Jim Palmer, vice president, Navigation Solutions. “It is a collaborative effort with NovAtel Inc. and its patented Narrow Correlator signal tracking technology.”

The CMA-6024 aviation GPS/SBAS/GBAS sensor, featuring an embedded VHF Data Broadcast (VDB) receiver, is a complete, self-contained, fully certified precision approach and navigation solution, certified to Design Assurance Level A (DAL-A). Designed as an easy-to-integrate solution for all aircraft, the plug-and-play tandalone unit requires no specialized installation or integration support.

The CMA-6024 provides a navigation solution that is fully compliant with Automatic Dependent Surveillance-Broadcast (ADS-B) and Required Navigation Performance (RNP). The CMA-6024 includes SBAS Localizer Performance/Localizer Performance with Vertical Guidance (LP/LPV) and GBAS GNSS Landing System (GLS) GAST-C/D Precision Approach guidance for all aircraft. The CMA-6024 meets or exceeds the most stringent environmental requirements set out in RTCA/DO-160G and goes further to meet additional requirements for specific aircraft.

Built on the successes of the CMA-5024, the CMA-6024 is the next evolutionary step forward that adds a complete GBAS/GLS solution. All CMA-5024 receivers can be upgraded to a CMA-6024. All of the benefits of the CMA-5024 are retained and a new self-contained GBAS/GLS functionality has been added to produce the CMA-6024.

CMC’s family of GPS products includes the CMA-5024 GPS Landing System Sensor that meets the requirements for an Instrument Flight Rules, civil certified Global Navigation Satellite System (GNSS). The European Geostationary Navigation Overlay Service (EGNOS), a component of SBAS, augments GPS to provide an extremely accurate navigation solution that will support all flight operations from en route through Localizer Performance with Vertical Guidance (LPV) CAT-l equivalent approach. The CMA-5024 is compliant with and completely supports EGNOS/SBAS, from departure, en-route navigation, and all EGNOS/SBAS LPV Precision Approaches, and complies with published Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) navigational mandates.

CMC is a wholly owned subsidiary of Esterline Corporation, a specialized aerospace and defense company headquartered in Bellevue, Washington, that employs over 13,000 people worldwide.
