The flexible nature of DO-178C's processes and entry/exit criteria make it difficult to implement the first time, because these aspects are abstract and there is no "base set" of activities from which to work. 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.
Various standards suggest different levels, e.g. Software Levels A-E in DO-178C, [4] SIL (Safety Integrity Level) 1-4 in IEC 61508, [1] ASIL (Automotive Safety Integrity Level) A-D in ISO 26262. [2] The assignment is typically done in the context of an overarching system, where the worst case consequences of software failures are investigated.
Given ASIL is a relatively recent development, discussions of ASIL often compare its levels to levels defined in other well-established safety or quality management systems. In particular, the ASIL are compared to the SIL risk reduction levels defined in IEC 61508 and the Design Assurance Levels used in the context of DO-178C and DO-254. While ...
The Certification Authorities Software Team (CAST) is an international group of aviation certification and regulatory authority representatives. The organization of has been a means of coordination among representatives from certification authorities in North and South America, Europe, and Asia, in particular, the FAA and EASA.
Like DO-178C and DO-278A, it is a joint RTCA undertaking with EUROCAE and the document is also published as ED-94C, Supporting Information for ED-12C and ED-109A. [2] The publication does not provide any guidance additional to DO-178C or DO-278A; rather, it only provides clarification for the guidance established in those standards. [3]
The US FAA have similar functional safety certification processes, in the form of ARP4761, US RTCA DO-178C for software and DO-254 for complex electronic hardware, [7] [8] which is applied throughout the aerospace industry. Functional safety and design assurance on civil/commercial transport aircraft is documented in SAE ARP4754A as functional ...
