摘　　要：本文主要目的在于分析COTS在民用飞机软件中的使用和取证。通过分析国际上绝大多数适航管理部门认可的软件合格审定指南RTCA DO-178B《机载系统和设备合格审定中的软件考虑》,理解只有满足RTCA DO-178B中的全部软件生命周期数据的COTS软件才是可以通过合格审定的,以及飞机的主制造商应该从COTS供应商那里获取到的符合RTCA DO-178B中所有目标的信息用来取证。如果COTS供应商不能够提供足够的取证信息,那么也可以考虑一些方法供飞机的主制造商来采用,最终能够实现COTS的适航取证。This paper aims to analyze the application and certification for COTS software in Civil Air‐craft Software Design .Through the analysis of RTCA DO -178B ,＆quot;Software Considerations in Air‐borne Systems and Equipment Certification＆quot;,the most acceptable guideline for software certification in the world ,it is clear to understand only certain COTS software with fully compliance to software life cycle process in RTCA DO -178B are certifiable .The aircraft manufacturers need to require the appropriate information that can satisfy all objectives required in RTCA DO -178B from COTS suppli‐ers .If the COTS supplier could not provide enough certification information ,there are several meth‐ods that the aircraft manufacturers are able to apply for COTS certification .
