These are all popular terms for the same document: RTCA/DO-178B: Software Considerations in Airborne Systems and Equipment Certification. RTCA is the acronym for Radio Technical Commission for Aeronautics and is located at 1828 L Street, NW, Suite 805, Washington, D.C. 20036. RTCA/DO-178B was developed by the commercial avionics industry to establish software guidelines for avionics software developers. The first version, DO-178 covered the basic avionics software lifecycle. The second version, DO-178A, added avionics software criticality level details and emphasized software component testing to obtain quality. The current version, DO-178B, evolved avionics software quality via added planning, continuous quality monitoring, and testing in real-world conditions. Technically, DO-178B is merely a guideline. In reality, it is a strict requirement. At merely 100 pages, DO-178B is all things to all people, which means it is quite broad in nature and requires in-depth understanding of intent, voluminous ancillary documentation, and case studies to be properly used
