Any software that commands, controls, and monitors safety-critical functions should receive the highest DAL - Level.
Furthermore, processes (and their concrete activities) must have well defined entry and exit criteria, according to DO-178B, and a project must show that it is respecting those criteria as it performs the activities in the process.
It was jointly developed by the safety-critical working group rtca SC-167.In the United States, the introduction of TSOs into the airworthiness certification process, and by extension DO-178B, is explicitly established in Title 14: Aeronautics and Space of the.DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems.The, fAA applies DO-178B as the document it uses for guidance to determine if the software will perform reliably in an airborne environment, 1 when specified by the Technical Standard Order (TSO) for which certification is sought.Requirements management edit Requirements traceability is concerned with documenting the life of a requirement.Contents, software level edit, the, software Level, also known as the, development Assurance Level (DAL) or also Item Development Assurance Level (idal) 2 is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system.This objective-based nature of DO-178B allows a great deal of flexibility in regard to following different styles of software life cycle.2018 m All Right Reserved.
