飞行数据不仅为事故分析提供科学的依据,也为航空管理部门的日常监控工作提供必须的数据来源。本文介绍了飞行数据分析与动态再现系统 FDAV 的实现方法。首先概述了飞机上飞行数据记录器的发展现状以及记录器的记录格式,并从软件及硬件方面提出了对飞行数据进行译码的技术。文中以 B737 的非线性参数为例具体说明了译码软件的设计思想,进一步详细讨论了如何利用译码后的数据结合航空公司制定的有关飞行标准分析事故原因、评估飞行员的技术、作出有关事件报告、实现飞行仪表及飞行轨迹的动态再现。飞行数据分析与动态再现系统 FDAV 已在 B737、B757、B767、A320机型上得到验证。
Flight data not only provide a scientific basis for accident analysis, but also provide necessary data sources for the daily monitoring of the aviation administration. This paper introduces the implementation of FDAV, a flight data analysis and dynamic reproduction system. First of all, the status quo of flight data recorder on aircraft and the record format of recorder are outlined. And the technology of decoding flight data is proposed in terms of software and hardware. In this paper, the non-linear parameters of B737 as an example to illustrate the design of decoding software to further discuss in detail how to use the decoded data with the airline to develop standards related to flight accident analysis of the reasons for assessing the pilot’s technology to make the incident Report, to achieve the dynamic reproduction of flight instruments and flight path. Flight data analysis and dynamic reproduction system FDAV has been verified on the B737, B757, B767 and A320 models.
