摘要
航空安全问题一直是人们关注的重点,QAR作为快速存储记录器可以记载飞机上的各种数据,通过这些数据可以还原事件状况或预测飞机性能故障,以此来避免事故的发生。虽然QAR数据的数量和种类巨大,用户群体也在逐渐扩大,但是对QAR数据的认识和应用还很有限。重点梳理了目前民航对QAR数据的主要应用及处理方法,并对这些方法做出比较和分析,最后通过实例说明QAR数据在发动机监控中的具体应用。
Aviation safety is one of the key issues that people concern about.Quick Access Recorder（QAR）is a device that is able to smartly record a variety of data on aircrafts,by the data that QAR recorded,the accident situation could be restored and the performance problem of aircrafts could be predicted so that the accident could be avoided.However,the knowledge and application of QAR data is limited though it records a huge amount and kind of data and the number of users increases considerably.This paper aims at sorting the application and processing methods toward QAR data in civil aviation,then comparing and analyzing the methods,and illustrating the practical applications of QAR data in the process of engine monitoring detection in details.
