the upper end to a steering collar and at the lower end to the shock strut
inner cylinder transmit a turning moment supplied by hydraulically
actuated steering cylinders. The steering is controlled by the handwheel on
the pilots sidewall or by the rudder pedals. The handwheel can turn the
nose wheel 78 from center and the rudder pedals at full deflection can turn
the nose wheel 7 from center.

二、TEXT
(1) the flight controls provide maneuvering control about the lateral,
longitudinal, and vertical axes. They also provide increased lift for take off
and landing as well as increased aerodynamic drag both in flight and on
ground. Flight controls are divided into two major groups: primary and
secondary. The primary flight controls consist of the ailerons, elevators,
and rudder. The secondary flight controls consist of the spoilers, trailing
edge flaps, leading edge devices, and the stabilizer.We will introduce the
primary flight controls in this lesson.
飞行控制系统提供水平、纵向及垂直方向上的机动控制。它们同时也
为飞机在地面起飞时提供升力及从空中降落时提供空气阻力。飞控系
统分为两个主要部分：主飞控系统及次飞控系统。主飞行控制系统包
含副翼、升降舵及方向舵。次飞控系统包含扰流板、后缘襟翼、前缘
襟翼及水平安定面。本课主要讲述主飞控系统。
(2) The aileron control system provides the means of rotating the airplane
about the longitudinal axis. The aileron control system is actuated by
rotation of either the captain’s or first officer’s aileron control wheel. The
autopilot system also provides a control input. These inputs control a
hydraulic powered system which drives the ailerons. Moving the ailerons
out of their trimmed position causes the airplane to ratote and change
attitude. The angular amount of control surface moved establishes the
“rate-of –change”.When the desired magnitude of attitude change has
been reached, the control surfaces are refaired, total forces acting on the
airplane are balanced and the airplane remains stable in a bank angle.
Since the airplane is in a bank, the wing loses some of its lift, so up
elevator command is used by the pilot or by the autopilot.
副翼控制系统提供飞机纵向转动的方式。副翼控制系统通过转动机长
或副驾位的副翼控制轮作动。自动驾驶系统也可提供控制输入。这些
输入控制驱动副翼的液压动力系统。转动副翼离开配平位置，致使飞
机转动并改变姿态。控制面角度的移动形成“变化率”。当姿态变化
达到希望的量值时，控制面再成流线型，作用在飞机上的合力达到平
衡，同时飞机在一个角度上保持稳定。因飞机有一定的角度，机翼升
力降低，所以驾驶员或自动驾驶系统会给出升降舵上升的命令。
(3) The ailerons are located on the outboard trailing edge of each wing.
Other aileron components are located in 3 main areas:
Flight deck
The control wheels are located in the forward portion of the flight
deck. The aileron trim switch is located on the control stand.
Wheel well area
The aileron power control units(PCU, convert a pilot or autopilot
mechanical driven input to a hydraulic power driven mechanical output to
drive the aileron) are located on the forward wall of the main wheel well.
The autopilot aileron actuators are located on the forward wall of the main
wheel well. The aileron position sensor provides two feedback postion
signal from the aileron system to the A/P system.
Lower nose compartment
The control drum and bus drum are connected to the control wheel,
