TSO authorization granted for Universal Avionics AHS-525 AHRS

The Federal Aviation Administration (FAA) has granted Technical Standard Order (TSO) authorization for Universal Avionics AHS-525 Attitude Heading Reference System (AHRS). This long-awaited approval allows the company to manufacture and bring to market a new addition to its product line. The AHS-525 is positioned as a low cost option for replacing legacy mechanical VGs and DGs in Part 23 and Part 25 Fixed Wing aircraft, and Part 27 and Part 29 Rotorcraft. The AHS-525 contains multiple rate gyros to measure angular aircraft motion in the pitch, roll and yaw axes, and several accelerometers to measure aircraft linear motion along the longitudinal, lateral and vertical axes of the aircraft. It is a cost-effective solution for replacement of fragile mechanical “spinning” gyroscopes.
