The performance engineer's daily work in the airline is that making the low-speed performance analysis and route operation evaluation by the software performance corresponding to aircraft model,it has a large amount of daily performance calculation. The research is oriented by pre-flight performance assis-tant calculation of performance engineer, the aircraft performance auxiliary calculation software was de-signed and developed. First it established basic performance database of civil aircraft,including aerody-namic data and engine thrust data,the programming language was used in order to complete the primary basic performance calculation, senior professional performance calculation performance curves output of the three main module design,the daily work of the performance engineers achieved quick and simple cal-culation,it laid the data foundation for the follow-up aircraft professional performance calculation,at the same time,it can offer help for the daily performance training of flight dispatcher.%航空公司性能工程师的日常工作就是使用机型对应的飞机性能软件进行低速性能分析和航线评估,日常计算量很大.面向性能工程师的前期飞行性能辅助计算工作,设计并开发了一款飞机性能辅助计算软件,建立机型基础性能数据库,包含气动数据和发动机推力数据,采用编程语言依次完成初级基础性能计算、高级专业性能计算、性能曲线绘制3个主要模块设计、实现性能工程师日常工作的快捷和简便性计算,为后续专业飞机性能计算打下数据基础,同时也可以为飞行签派员的日常性能训练工作提供帮助.
