CMC Electronics’ IntegriFlight CMA-5024 aviation Global Positioning System (GPS) receiver was certified recently by the Federal Aviation Administration (FAA) and Transport Canada to TSO-C145b Beta-3 and TSO-146 Delta-4. The C145 Beta-3 is the most stringent category for Wide Area Augmentation System (WAAS) navigation receivers and the C146 Delta-4 category allows these receivers to provide Precision Approach guidance signals to the aircraft’s autopilot and instrument displays to execute a localizer precision with vertical (LPV) approach.

The CMA-5024 is a ruggedized air transport quality WAAS/GPS receiver specifically designed for easy retrofit and adaptability to either existing or new build aircraft. Owing to its compact and rugged nature, and a predicted 40,000 h mean-time-between-failure, it is said to be an ideal solution across a wide range of aircraft, from helicopters and business jets to air transport.

The CMA-5024 provides space-based augmentation system/WAAS GPS navigation capability from departure to non-precision approach that will comply with published communications, navigation, surveillance/air traffic management navigational mandates and growth provisions. When coupled with a compatible flight management system or the companion CMA-5025 control panel from Air Data (www.airdata.ca), the CMA-5024 will provide LPV approach guidance identical to instrument landing system (ILS) localizer and glide slope signals.

The IntegriFlight CMA-5024 has numerous interfaces conforming to ARINC 743A-4 and supports the new ARINC 743A-5/743B Characteristics. As a sensor, the CMA-5024 provides high-performance position, velocity, and time supporting all automatic dependent surveillance-broadcast requirements, primary means navigation, and required navigation performance (RNP)-area navigation capable flight management systems. As a result, any flight management system can immediately benefit from the improved navigation accuracy, integrity and availability.

The CMA-5024 is a self-contained GPS approach system that can host two cycles of the entire world-wide WAAS approach database. GPS approach selection can be made from a suitable FMS or a dedicated control head (CMA-5025). The CMA-5024 provides ILS look-alike localizer and glideslope guidance signals, linear deviations, and distance to go for seamless integration with RNP operations, distance measuring equipment look-alike distance to go to the threshold crossing point, and supports analog avionics, autopilots, and flight directors.
