The intention of DO-178C was not to be prescriptive. There are many possible and acceptable ways for a real project to define these aspects.

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.
Although technically a guideline, it was a de facto standard for developing avionics software systems until it was replaced in 2012 by DO-178C. The Federal Aviation Administration (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 ...
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.
