DO-178 and DO-254 Avionic Training Bootcamp by Tonex


The DO-178 is currently used for avionics software development and testing the applications and reliability of such software. DO-254 is the document that provides guidelines for the development of electronic aviation hardware.

Today, DO-254 provides guidelines for hardware development based on a variety of criteria. At its most basic, the document splits hardware components into two categories:

Simple Hardware Items: Hardware is classified as simple if a comprehensive combination of deterministic tests and analyses can ensure correct functional performance under all foreseeable operating conditions with no anomalous behavior.

Complex Hardware Items: Hardware is automatically classed as complex if it fails to meet the definition of a simple item. In other words, complex items have less predictable behavior than simple ones.

The current version of DO-178 used in avionics is DO-178C.

The FAA approved AC 20-115C on 19 Jul 2013, making DO-178C a recognized acceptable means, but not the only means, for showing compliance with the applicable airworthiness regulations for the software aspects of airborne systems and equipment certification.

DO-178C is the primary document by which the certification authorities such as FAA, EASA and Transport Canada approve all commercial software-based aerospace systems.

DO-178C replaced DO-178B to be the primary document by which the certification authorities will approve all commercial software-based aerospace systems. It represents a revision to DO-178B considering the experiences and information gathered for developing software for avionics.
