显示系统使用SCADE工具链的适航符合性研究

Research on Airworthiness Compliance of SCADE Tool Chain Used in Display Systems

本文介绍了SCADE工具链在民机显示系统软件开发中的使用方法,根据工具使用过程中替代的DO-178目标,结合DO-330相关规则识别了SCADE工具链中哪些工具需要做鉴定以及相应的鉴定级别,针对需要鉴定的工具,为满足被替代的目标,由工具开发方和使用方提供适航数据和适航活动,为SCADE工具链在民机开发活动中的工具鉴定提供了一套完整的适航符合性策略方法,对于其它使用SCADE工具链的民机软件开发活动提供了有益的指导。

The application of SCADE tool chain in the software development of civil aircraft display system is intro-duced.According to the DO-178 target replaced in the process of tool use,combined with the relevant rules of DO-330,tools and their corresponding levels in the SCADE tool chain to be certified are identified.The airworthiness data and activities required by the tool developer and user are analyzed to meet the replaced objectives for the tools that need to be certified.It provides a complete set of airworthiness compliance strategy methods for the tool identification activities of SCADE tool chain in civil aircraft development activities,and provides useful guidance for other civil aircraft soft-ware development activities using SCADE tool chain.
