摘　　要：随着数字化航电系统的发展,飞行数据记录系统越来越向着综合化数据记录的方向发展,根据数字化飞行数据记录器对综合数据尤其是音视频数据采集的需要,设计和实现了飞行数据综合纪录与分析系统,该系统不仅可进行的飞行数据特别是音视频数据的采集和存储,还对数据量庞大的音视频数据进行基于MPEG4的压缩。系统集中管理分布式数据,存储并能提供数据回放分析功能。分析这些音视频数据,对于更准确的评估飞行训练水平具有十分重要的现实意义。With the development of integrated digitized avionics system, flight data recorder have become more and more to record the integrated data, depending on the requirement of digitized data collection system especially the requirement of the audio and video data, designed and realized on-aero integration data collection and analysis system. The system is not only used to collect and store on-aero integration data especially the audio and video data, but also can compress the audio and video data based on the MPEG4. The system centralize different kinds of distributed data, stores them and applies the functions to review and analysis the stored flight data, The analysis of the data including the audio and video data is important to evaluate flight quality exactly.
