摘　　要：国内投入国产机载设备研制的单位,尽管技术底蕴丰富,但适航经验不足:尚不能完全理解软件适航标准DO-178C对软件研制过程的要求,当存在软件供应商时,更是忽略了对软件供应商的监督。在研究和分析DO-178C提及的软件供应商要求的基础上,根据符合性数据提供方的不同,对软件供应商的适航管理方式进行了区分。并进一步提出了申请人对软件供应商的管理分两步走的策略:第一是供应商软件按照DO-178C对机载软件的要求适航;第二是申请人实施对供应商的监督。该策略成功实施于多个CTSOA项目的适航审定工作中,有效地帮助申请人理清了软件供应商的适航管理思路,提升了审定效率。With the vigorous development of China’s large aircraft industry,the flag of“localization”has been raised high.In batches of units invested in the development of domestic airborne equipment,despite rich technical heritage,but lack of airworthiness experience:it is not yet able to fully understand the requirements of software air⁃worthiness standard DO-178C on the software development process,when there is a software supplier,it is ignored to supervise the software supplier.Based on the research and analysis of the requirements of software suppliers mentioned in DO-178C,this paper distinguishes the airworthiness management methods of software suppliers ac⁃cording to the different compliant data providers,and further puts forward a two-step strategy for the management of software suppliers:firstly,the supplier’s software is airworthiness according to the requirements of DO-178C for airborne software;secondly,the applicant should supervise the supplier.This strategy has been successfully implemented in the airworthiness certification work of several CTSOA projects,effectively helping applicants to clarify the airworthiness management ideas of software suppliers,and improving the certification efficiency.
