AHR 150A Air Data Attitude Heading Reference System Pictured: Boeing CH-47 Chinook The AHR150A ADAHRS (Air Data Attitude Heading Reference System) from Archangel Systems represents a paradigm shift in the ADAHRS Qualified for Mission Critical applications including IFR, SAR, and primary flight systems market. Using MEMS sensors and sophisticated blending algorithms, the ADAHRS yields “FOG-grade” performance at greatly reduced size, weight, power, and cost. Several companies, including The Boeing Company, Erickson Corporation, and Airbus, have selected the AHR150A for their supplemental and type certificates in rotary- and fixed-wing platforms. Rate limits for the AHR150A are ±128°/second. A variant, the AHR300A, reaches ±256°/second and is similarly certified. And, with multiple high- and low-speed ARINC 429 ports, both products seamlessly integrate into any avionics suite. Certified for Part 23, 25, 27, and 29 aircraft Air data is RVSM compliant Designed with low data latency for fly-by-wire aircraft Directional Gyro mode meets TSO C5f requirements Mil Spec 38999 filtered connectors Angle rate limit of ±128°/second (±256°/second on the AHR300A) CERTIFICATIONS DO-178B Level A software FAA TSO C4c, C5f, C6e, C88b, and C106 EASA—All equivalent ETSOs DO-160E Environmental certifications including EMI, EMC, and HIRF Exportable worldwide No end-user statement required www.archangel.com 334.826.8008 x 22 lets.talk@archangel.com Dan Reida – Director of Sales
