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.
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 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.
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]
It is a misunderstanding that by purely syntactic rearrangements of decisions (breaking them into several independently evaluated conditions using temporary variables, the values of which are then used in the decision) which do not change the semantics of a program can lower the difficulty of obtaining complete MC/DC coverage. [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 ]
Honey, they shrunk the catalogs. While retailers hope to go big this holiday season, customers may notice that the printed gift guides arriving in their mailboxes are smaller. Many of the millions ...
The DO-254/ED-80 standard is the counterpart to the well-established software standard RTCA DO-178C/EUROCAE ED-12C. With DO-254/ED-80, the certification authorities have indicated that avionics equipment contains both hardware and software, and each is critical to safe operation of aircraft .
