飞行管理系统下降路径构建及应用研究

在飞行管理系统下降设计中，通过下降路径的构建可为接近目的机场提供一个垂直轨迹，使飞机遵守终端区各种限制要求，从而精确控制下降路径，满足安全性要求。本文分析了下降路径的定义及其在典型机型中的构建方法，给出了下降路径的描述方法及实现途径，并对具体机型中的应用做了简要介绍。

Research on Constructing and Using Descent Path Created by Flight Management System

In descent flight phase design of flight management system (FMS), the constructed descent path is intended to provide a vertical track to the proximity of the destination airport. The path accounts for all descent waypoint constraints such that none are violated, so the aircraft can control descent path accurately and meet the security requirements. This paper analyses the conception and construction method of descent path created by typical aircraft FMS, and it describes descent table and some ideas for using the descent path in specific aircraft.
