摘要
国内软件制造商在对参数数据项进行适航审定时存在审定策略不明确、符合性证据不足等问题。基于国际通用的软件标准DO-178C,解析并梳理参数数据项适航的目标要求,并结合国内适航审定工作中的不足和审定工作实践,提出参数数据项的适航审定策略:1)嵌入式参数数据项作为机载软件的一部分进行适航审定;2)独立式参数数据项作为独立的软件构型,按照本文建议的计划、开发和验证过程进行研制过程保证和适航。实践表明:本文所建议的参数数据适航审定策略有效地解决了国内软件制造商参数数据项适航工作中存在的问题,为参数数据项的适航审定提供了高置信度的符合性证据。
In terms of the airworthiness certification of parameter data item,domestic software manufacturers have some problems,such as unclear certification strategy and insufficient evidence of conformity.Based on the international general software standard DO-178C,combined with the shortcomings of domestic airworthiness certification work and certification practice,the airworthiness objectives and requirements of parameter data item are analyzed,and the suggested airworthiness certification strategy of parameter data item is put forward:1)Embedded parameter data item as a part of the onboard software for airworthiness certification;2)Independent parameter data item as an independent software configuration,according to the proposed planning,development and verification process for development process assurance and airworthiness.Practice shows that this strategy effectively solves the problems existing in the airworthiness work of parameter data item in domestic software manufacturers,and provides high confidence proof of conformity for the airworthiness certification of parameter data item.
