DO-178C, Software Considerations in Airborne Systems and Equipment Certification is the title of the recently published document from RTCA, Incorporated, in a joint effort with EUROCAE. This replaces DO-178B as the primary document by which the certification authorities such as FAA, EASA and Transport Canada will approve all commercial software-based aerospace systems. The new document is called DO-178C/ED-12C and was completed in November 2011 and approved by the RTCA in December 2011. It became available for sale and use in January 2012.〔(http://www.rtca.org/store_list.asp )〕 The FAA approved AC 20-115C〔http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC_20-115C.pdf〕 on 19 Jul 2013, making DO-178C a recognized "acceptable means, but not the only means, for showing compliance with the applicable airworthiness regulations for the software aspects of airborne systems and equipment certification." == Background == Since the release of DO-178B, there have been strong calls by DERs (FAA Designated Engineering Representatives) for clarification/refinement of the definitions and boundaries between the key DO-178B concepts of high-level requirements, low-level requirements, and derived requirements and a better definition of the exit/entry criteria between systems requirements and system design (see ARP4754) and that of software requirements and software design (which is the domain of DO-178B). Other topics such as what does verification mean in a model-based development paradigm and can model simulation or formal methods replace some or all software testing activities. The release of DO-178C and the companion documents DO-278A (Ground Systems), DO-248C (Additional information with rational for each DO-178C objective), DO-330 (Tool Qualification), DO-331 (Modeling), DO-332 (Object Oriented), and DO-333 (Formal Methods) were created to address the issues noted. The SC-205 members worked with the SAE S-18 committee to assure that APR4754A and the above noted DO-xxx documents provide a unified and linked process with complimentary criteria. Overall, DO-178C keeps most of the DO-178B text, which has raised concerns that issues with DO-178B, such as the ambiguity about the concept of low-level requirements, may not be fully resolved. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DO-178C」の詳細全文を読む スポンサード リンク
