Airborne Electronic Hardware Design Assurance A Practitioner's Guide to RTCA/DO-254

Written by a Federal Aviation Administration (FAA) consultant designated engineering representative (DER) and an electronics hardware design engineer who together taught the DO-254 class at the Radio Technical Commission for Aeronautics, Inc. (RTCA) in Washington, District of Columbia, USA, Airborne Electronic Hardware Design Assurance: A Practitioner's Guide to RTCA/DO-254 is a testimony to the lessons learned and wisdom gained from many years of first-hand experience in the design, verification, and approval of airborne electronic hardware.

This practical guide to the use of RTCA/DO-254 in the development of airborne electronic hardware for safety critical airborne applications:

• Describes how to optimize engineering processes and practices to harmonize with DO-254
• Addresses the single most problematic aspect of engineering and compliance to DO-254?poorly written requirements
• Includes a tutorial on how to write requirements that will minimize the cost and effort of electronic design and verification
• Discusses the common pitfalls encountered by practitioners of DO-254, along with how those pitfalls occur and what can be done about them
• Settles the ongoing debate and misconceptions about the true definition of a derived requirement
• Promotes embracing DO-254 as the best means to achieve compliance to it, as well as the best path to high-quality electronic hardware

Airborne Electronic Hardware Design Assurance: A Practitioner's Guide to RTCA/DO-254 offers real-world insight into RTCA/DO-254 and how its objectives can be satisfied. It provides engineers with valuable information that can be applied to any project to make compliance to DO-254 as easy and problem-free as possible.

Randall Fulton has more than 36 years of electrical engineering experience in software and electronic hardware development and verification. He holds a BS from the Pennsylvania State University and earned his FAA DER credentials in software and programmable logic devices while working at Boeing Commercial Aircraft. As a DER, he has had approval authority for programmable logic devices since 1997 and has worked numerous Part 23 and Part 25 certification programs with field programmable gate arrays, ASIC, and software. Randall, along with Roy Vandermolen, taught the DO-254 practitioners course for RTCA in Washington, DC from 2006 to 2009. Randall has also taught the Airborne Electronic Hardware Job Functions class for the FAA Academy in Oklahoma City. He currently works as an FAA consultant DER through his company SoftwAir Assurance, Inc.

Roy Vandermolen is an electronics design engineer with more than 35 years of experience ranging from vacuum tubes to programmable logic devices, but has spent the majority of that time designing and verifying programmable logic devices and the circuit cards that employ them. Roy holds a BS from the Massachusetts Institute of Technology, and is currently a staff engineer and certification manager for electronic flight control systems at Moog Aircraft and an airborne electronics hardware OBAR for Boeing Commercial Aircraft. Roy has worked in a variety of research laboratories, educational institutions, military R&D facilities, and commercial aircraft flight controls manufacturers. At Moog Aircraft, Roy has been involved in the design, verification, and certification of numerous Level A flight control systems. Roy, along with Randall Fulton, taught the DO-254 practitioners course for RTCA in Washington, DC from 2006 to 2009.
