说明：  利用VAPS XT软件模仿飞机仪表系统所建立的PFD和ND可以实现重现飞机在飞行过程中的姿态，航线等关键的飞行数据，进而分析出飞机的事故原因和安全隐患。 本论文主要深入研究了基于PFD虚拟仪表系统的飞行数据综合参数回放，这是飞行数据回放系统的一项重要技术,目的在于实现飞行数据管理记录系统中飞行数据回放的论证方案
(The use of VAPS XT software to imitate the aircraft instrument system established by the PFD and ND can reproduce the aircraft in the flight process of the attitude, flight routes and other key flight data, and then analyze the causes of the aircraft accident and security risks. This paper mainly studies the comprehensive parameter replay of flight data based on PFD virtual instrument system. This is an important technology of the flight data playback system. The purpose of this paper is to implement the demonstration scheme of flight data playback in the flight data management record system.)
