中文摘要：

飞行数据译码分析是进行飞机状态监控、故障诊断与维修、飞行品质分析等的重要技术手段。介绍了QAR记录的原理,在分析了传统译码算法及译码的缺点的基础上,针对ARINC717协议中的飞行参数类型,提出了基于参数类型的动态链表快速译码算法,并开发了基于实时数据库技术的快速译码系统软件,显著提高了飞行数据的译码效率,扩展性好,能满足飞行记录数据新应用的实时快速译码要求。

英文摘要：

The decoding analysis of the flight data is an important technical means of monitoring the airplane＇s condition,diagnosing the failure,analysis the flight quality,and so on.The principle of QAR recording flight data is introduced firstly,then the traditional decoding algorithm and software＇s defects are analyzed.In view of the parameters type in ARINC717 agreement,a quick decoding algorithm based on dynamic list is proposed.And the software of quick decoding system based on the technology of real-time database is implemented.The new method significantly improved the efficiency of the decoding of flight data,scalability,and it can meet the requirements of real-time fast decoding for flight data＇s new application.
