RTCA DO-254 / EUROCAE ED-80, Design Assurance Guidance for Airborne Electronic Hardware is a document providing guidance for the development of airborne electronic hardware, published by RTCA, Incorporated and EUROCAE.

Describe how to apply the DO-254 lifecycle and supporting processes, understand system safety assessments and the design assurance level (DAL), set up a project correctly through proper planning and standards.

Apr 19, 2000 · RTCA DO-160/EUROCAE ED-14, Environmental Conditions and Test Procedures for Airborne Equipment, may be used by equipment designers as the primary environmental test standard for hardware item qualification.

DO-254 provides guidance in terms of the objectives you must meet in the certification process. How you comply with DO-254 and meet those objectives is up to you.

In this paper, we will explore the safety-related concepts of requirements traceability, design assurance levels, the overall DO-254-compliant flow as documented in the spec, and several other aspects that might not be well documented but are critical to project approval.

This order explains how Federal Aviation Administration (FAA) aircraft certification staff can use and apply RTCA, Inc. document RTCA/DO-254, Design Assurance Guidance for Airborne Electronic Hardware, when working on certification projects. In this order you’ll find discussion and FAA interpretation of RTCA/DO 254 sections.

This document is intended to help aircraft manufacturers and the suppliers of aircraft electronic systems assure that electronic airborne equipment safely performs its intended function. The document identifies design life cycle processes for hardware that includes line replaceable units, circuit board assemblies, application specific integrated circuits (ASICs), programmable logic …

For airborne electronic hardware contributing to hardware DAL D functions, the acceptable means of compliance include ED-80/DO-254 or existing level D hardware development assurance practices that demonstrate that the requirements allocated to the DAL D airborne electronic hardware have been satisfied.

RTCA/DO-254 distinguishes between complex and simple electronic hardware; recognizes five classes of failure conditions, from catastrophic to no effect; and provides guidance for each hardware design assurance level associated with a given failure condition classification.

The RTCA DO-254 standard is an important standard for aviation safety and certification. It is used to ensure that the design process of airborne electronic hardware (EHW) meets specific safety requirements in order to minimize or eliminate any potential risks that could be caused by incorrect design or engineering.
