Harlow Aerostructures and Verocel Achieve FAA Certification Approval of HAT-05 Autothrottle System

Autothrottle system is designed for FAR Part 23 light aircraft improving safety and reliability. Verocel's expertise key in enabling DO-178C certification.

WESTFORD, MA, UNITED STATES, September 5, 2017 / -- Verocel®, a leader in airborne software and complex hardware certification and Harlow Aerostructures, a leading aerospace manufacturer based in Wichita KS, announced that Harlow’s HAT-05 Autothrottle system has received FAA approval. Designed for use on general aviation aircraft with full-authority electronic digital controls (FADEC), the HAT-05 interfaces with automatic flight control systems and flight management systems to reduce pilot workload and improve engine efficiency.

The HAT-05 is the latest autothrottle design from Harlow Aerostructures and is designed for use with twin engine, technically advanced aircraft in either an OEM or retrofit application. The HAT-05 reduces pilot workload by managing the engine’s fuel parameters for all flight conditions. It uses inputs from the autopilot and flight management computer to ensure maximum efficiency. Harlow designed the hardware and software and needed a partner to assist in meeting the stringent objectives for software certification. Verocel's expertise in software verification and validation ensured that the HAT-05 software could meet DO-178C objectives.

"Verocel is proud to be a partner with Harlow Aerostructures in enabling our mutual customers to improve the next generation general aviation platforms” said Joe Wlad, Vice-President, Business Development at Verocel. “Our work with Harlow required close collaboration between the two engineering organizations as well as with FAA representatives."

"We are very excited to be able to bring this type of affordable product to market," said Jim Barnes, President, Harlow Aerostructures. "Our partnership with Verocel enabled us utilize the expertise of the Verocel staff in software verification to achieve DO-178C certification in a timely and cost-effective manner."
