摘　　要：针对高工具鉴定等级的民用机载软件工具适航取证过程复杂、适航审查周期长和适航成本高昂问题,提出一种工具配对鉴定方法。分析工具配对鉴定方法的使用场景、评估工具配对鉴定策略的适航关注点,通过开发并鉴定一个配对的低等级验证工具有效替代高等级工具鉴定活动,进而优化适航策略、降低适航成本。某应用案例表明了工具配对鉴定方法的有效性,可为民用机载软件适航符合性策略优化提供支持和依据。To address the complex airworthiness certification process,long qualification cycle,and high airworthiness costs of civil airborne software tools with high tool qualification level(TQL),a tool pairing qualification method is proposed.By analyzing the usage scenarios of tool pairing qualification method and evaluating airworthiness concerns,this method aims to develop and qualify a validation tool with low TQL that can effectively replace high level tool identification activities,thereby effectively reducing airworthiness costs.The application case in a domestic civil aircraft model project demonstrates the effectiveness of the tool pairing qualification method,which can provide support and basis for optimizing the airworthiness compliance strategy of civil airborne software.
