Diagram illustrating the required bidirectional tracing between certification artifacts, as required by the RTCA DO-178C standard. Thin blue-colored traces and blue-filled boxes are required only for Level A. Purple-colored traces and purple-filled boxes are required for Levels A, B, and C. Thick green-colored traces and green-filled boxes are ...
The Advisory Circular AC 20-115( ), Airborne Software Development Assurance Using EUROCAE ED-12( ) and RTCA DO-178( ) (previously Airborne Software Assurance), recognizes [1] the RTCA published standard DO-178 as defining a suitable means for demonstrating compliance for the use of software within aircraft systems.
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.
The flexible nature of DO-178B'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-178B was not to be prescriptive. There are many possible and acceptable ways for a real project to define these aspects.
Many of RTCA documents begin with the letters DO which stands for DOcument. RTCA develops Minimum Operating Performance Standards for aviation-based technology (typically avionics) but has developed standards for such far-ranging topics as Airport Security, Counter UAS Detection standards, and Aircraft Cockpit and Cabin Cleaning standards.
These position papers were among the inputs to the joint RTCA/EUROCAE committee that developed DO-178C, DO-278A, DO-248C, and DO-330, and the technology supplements to these publications (DO-331, DO-332, and DO-333). [1] The model for international certification authority harmonization has changed since CAST's inception. [5]

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]
