(NBAA, Orlando – October 16, 2018) Esterline Avionics Systems is pleased to announce that Airborne Maintenance & Engineering Services has received FAA Supplemental Type Certificate (ST04319CH) approval of their ADS-B Out

solution featuring Esterline’s CMA-5024 on Boeing 757, 767-200 and 767-300 aircraft.

This STC pairs Esterline CMC Electronics’s CMA-5024 GPS/SBAS Landing System Sensor Unit (GLSSU) receiver with the new ACSS transponders to meet the latest DO-260B ADS-B out standards mandated worldwide for 2020. This STC solution includes many cost-saving features while minimizing aircraft downtime and upgrade expense thereby reducing overall out-of-service time per aircraft.

In addition to achieving compliance to the ADS-B Out directive, the CMA-5024 is an SBAS receiver that fulfills the FAA’s 2025 Satellite-Based Augmentation System (SBAS) requirements. It also offers aircraft the option to take advantage of SBAS navigation throughout all phases of flight, and provides a future growth LPV approach capability path.

An LPV approach is the highest precision GPS instrument approach available (with minima as low as 200 ft.) which does not require specialized crew training. It provides airlines with a safe approach into airports that are not equipped with ILS.

Additional growth to GBAS GLS precision approach capability may be obtained by upgrading to Esterline’s new CMA-6024 GPS/SBAS/GBAS Receiver System.

The CMA-5024 meets the requirements for an Instrument Flight Rules, civil certified Global Navigation Satellite System (GNSS). North America’s Wide Area Augmentation System (WAAS) and European Geostationary Navigation Overlay Service (EGNOS), both examples of SBAS, augment 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 support WAAS/EGNOS/SBAS, from departure, en-route navigation, and all WAAS/EGNOS/SBAS LPV Precision Approaches, and complies with published Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) navigational mandates.
