located in the lower nose compartment. The roll CWS force transducer is
connected between the bus drum and the control drum, the output of the
force transducer provides signals to the autopilot. The aileron force limiter
limits control wheel movement during A/P operation, the control wheel
rotation is limited to 17°with flaps up and 25°with flaps down.
副翼位于每个机翼前缘外侧，其它副翼组件位于3 个主要区域：
驾驶舱
控制轮位于驾驶舱前部。副翼配平开关位于控制台上。
轮舱区域
副翼动力控制组件（PCU，转变驾驶员或自动驾驶系统机械驱动的输
入为液压驱动机械输出，用以驱动副翼）位于主轮舱前壁。自动驾驶
副翼作动筒主轮舱前壁。副翼位置传感器从副翼系统提供两个位置反
馈信号给自动驾驶系统。
机头下方
控制鼓及转动鼓轮连接到控制轮上，位于机头下方。横滚驾驶盘操纵
反向换能器连接在转动鼓轮与控制鼓之间，力量转换器的输出为自
动驾驶提供信号。副翼操纵力限制器限制控制轮在自动驾驶仪操作时
移动。控制轮的转动被限制在襟翼上升17°及襟翼下降25°之间。
(4) To understand elevator poeration consider the airplane balanced about the
center of lift (CL). The center of gravity (CG) is shown forward of the
center of lift. The stabilizer provides a counter force to the CG. The
stabilizer may be trimmed to changer the force as required to maintain
balance.
The elevators are used to change the pitch attitude. Moving the elevators
out of their faired position causes the airplane to change the pitch attitude
about the lateral axis. The amount of elevator movement establishes the
airplane pitch rate.When the desired attitude is reached, the elevators are
faired and the air-plane maintains the new pitch attitude.
升降舵操作要考虑飞机相对于升力中心的平衡。重力中心一般在升力
中心的前面。安定面提供一个反向力给重力中心。安定面也可以在需
要时通过配平改变力量以保持平衡。
升降舵用来改变飞机俯仰姿态。移动升降舵离开它们的流线型位置，
使得飞机改变水平轴上的俯仰姿态。升降舵的移动量形成俯仰率。当
达到希望的姿态时，升降舵再成流线型，飞机保持新的俯仰姿态。
(5) Two control columns provide pitch control of the airplane . each control
column extends through the floor into the lower nose compartment. A
torque tube connects the control columns together. The control columns
allow the pilots to control the airplane about the lateral axis.
两个驾驶杆提供飞机俯仰控制。每个控制杆通过地板沿伸到前舱。一
个扭个管将驾驶杆连在一起。驾驶杆允许驾驶员沿水平轴控制飞机。
(6) Control about the vertical axis is provided by the rudder. Control is
provided by a single rudder without tab. The rudder is pedal operated by
the captain or the first officer. Pedal movement rotates the forward
quadrants, which are cable connected to the aft quadrant. Rotation of the
aft quadrant moves a control rod connected to a torque tube. Rotation of
the torque tube moves a crank connected to the rudder power control unit
linkage. This admits hydraulic fluid to the actuating cylinder, which
moves the rudder.
飞机垂直方向上的控制由方向舵提供。通过一个单独的不含调整片的
方向舵提供控制。方向舵由机长或副驾驶的脚蹬控制。随着脚蹬的移
动，使得前扇形盘转动，前扇形盘由线缆连接到后扇形盘。后扇形盘
的转动带动一个连接着一个扭力管的操纵杆。扭力管的转动带动了连
接着方向舵动力控制组件的曲柄移动，它提供液压压力给员筒型作动
筒，作的筒作的使得方向舵移动。
