TSO Authorization Granted for Universal Avionics AHS-525 AHRS

Cost-effective Solution for Replacement of Fragile Mechanical Gyroscopes

TSO Authorization Granted for Universal Avionics AHS-525 AHRS

Tucson, AZ – May 20, 2016 – 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.

“We are excited to be able to offer our customers a cost-effective, highly reliable solution for replacement of their older technology gyros,” said Dan Reida, Universal Avionics Vice President of Sales and Marketing. “Customers will benefit from simplified and reduced-cost retrofit installations, and reduced operating costs, weight, wiring and power consumption,” he added.

A single AHS-525 provides an opportunity to replace multiple Line Replaceable Units (LRU) found in a typical aircraft installation. The stand-alone AHS-525 offers Micro-Electromechanical (MEMS) technology that has all of the advantages of reliable solid-state technology, along with ease of alignment procedures, a compact and lightweight size, and increased reliability over VGs and DGs.
