x-plane.org上公开了一个X-Plane 11用的FMS操作手册。 里面提到 “This document may be copied and distributed by Laminar Research customers for entertainment only.” 那么本站就介绍一下。

关于这个飞行管理系统的模拟程度，手册中说： “Due to the immense complexity of a real-life Flight Management System, the version modelled in X-Plane 11 is simplified, and does not support every capability. However, the functions necessary to program and execute a flight plan are present, including the use of published arrival and departure procedures (SIDs and STARs) and instrument approaches.” 也就是提供了类似波音737的CDU的飞行计划功能，包括了SID和STAR和仪表进近。

CDU作为飞行计算机的输入设备，在X-Plane11中为一个弹出式(Pop-Up) 2D窗口， 可以用鼠标来控制它弹出，移动位置，改变大小，或者关闭窗口。

根据功能CDU内可以分为以下几个区域： 显示屏幕Display, 输入区Scratch Pad, 行选键Line Select Keys, 输入键Key Pad,

页面键Page Keys, 确定执行键Exec Key, 清除(删除)键Clear Key
