飞行数据可视化技术研究

Research on the Visualization Technology of Flight Data

针对航空器事故调查和不安全事件分析的结果及改进的需要,研究基于FDR/QAR/DAR/CVR的数据可视化技术。提出基于飞行仪表布局语言(FILL)的仪表模型构建与驱动的技术方案,解决FDR/QAR/DAR记录数据的导入与修正处理、不同分辨率三维地形的生成与显示以及飞行数据与驾驶舱话音同步播放等问题。实践证明,利用数据可视化技术所构建的包括飞机、航迹、仪表、地形、跑道、航图等元素的三维图形飞行环境集成再现了飞行过程,为事故调查和事件分析提供了科学有效的辅助分析工具。

To amend the flight data from the airborne FDR, QAR, DAR and CVR in accident investigation and unsafe-event analysis, the visualization technology of flight data is studied. A technological scheme for the FILL-based instrumentation modeling and driving is presented, which solves the problems of data importing and amending, flight path reconstructing, 3-dimentional （3D） terrain generation and picture-sound synchronization. It is proved that the 3D graphics flight environment established by the visualization technology of flight data can not only reproduce the flight process, but also provide scientific and effective tools for the accident investigation and incident analysis.
