飞行管理系统性能计算策略分析

摘要

根据飞行管理系统机载软件对于性能计算的需求,提出了理论公式计算方法和插值计算方法,对于传统的理论公式计算方法进行了延迟时间数据分析.对以上两种计算方法分别从计算过程、软件工程、系统工程三个方面进行了分析和比较后得出,插值计算方法在机载飞行管理系统软件中是比较合理的方法.针对大型客机先进的航空电子系统,描述了以上两种计算方法分别在电子飞行包软件和飞行管理机载软件中的不同应用和联系.%Based on the requirement of flight performance calculation of flight management system,this paper puts forward theory formula calculation and interpolation calculation,then analyses relay time data for traditional theory formula calculation,furthermore,compares and analyses such two calculation methods from calculation course,software engineering and system engineering,decides that interpolation calculation is more reasonable method.At last,this paper describes the different application and relation of two calculation methods in electronic flight bag software and flight management airborne software.
