DO-178C, Software Considerations in Airborne Systems and Equipment Certification is the primary document by which the certification authorities such as FAA, EASA and Transport Canada approve all commercial software-based aerospace systems.
MC/DC is used in avionics software development guidance DO-178B and DO-178C to ensure adequate testing of the most critical (Level A) software, which is defined as that software which could provide (or prevent failure of) continued safe flight and landing of an aircraft.
DO-178C and DO-254 define the design assurance objectives that must be accomplished for given DAL. Unlike SIL, it is the case that both ASIL and DAL are statements measuring degree of hazard. DAL E is the ARP4754 equivalent of QM; in both classifications hazards are negligible and safety management is not required.
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. It was jointly developed by the safety-critical working group RTCA SC-167 of the Radio Technical Commission for Aeronautics (RTCA) and WG-12 of the European ...
DO-178C [4] and DO-278A [5] require several activities (e.g. test coverage verification, assurance activities) to be executed “with independence”, with independence being defined as “separation of responsibilities which ensures the accomplishment of objective evaluation”.
U.S. Surgeon General Dr. Vivek Murthy warned in a recent advisory about alcohol use increasing cancer risk. The advisory notes that alcohol can increase the risk of throat, liver, esophageal ...
ARP4754 is intended to be used in conjunction with the safety assessment process defined in SAE ARP4761 (updated to Revision A in December 2023) and is supported by other aviation standards such as RTCA DO-178C/DO-178B and DO-254. This guideline addresses Functional Safety and design assurance processes.
