二、TEXT
(1) the navigation system compute and display the airplane’s position and
movement over the earth’s surface. The navigation systems include the
following main subsystems:
 ADF automatic direction finder — ADF system provide a display of the
relative bearing to a selected ground transmitter.
 VOR/ILS(very high frequency omnirange/instrument landing system)—
this system provide displays of relative and magnetic bearing to a selected
VOR station and deviation from a preselected course.When truned to an
ILS frequency, the system provides a display of the lateral and vertical
deviation from the optimum landing path.
 DOM(distance measuring equipment) —DME system measures the
slant range distance to the selected DME facility.
 ATC (air traffic control)— ATC system transmits airplane identification
and altitude data to a ground facility.
 ADS (air data system)— ADS system measures pitot and static pressure
and total air temperature and computes various air data parameters.
 IRS(inertial reference system)— this system provides outputs of key
navigation parameters such as heading, attitude, and airplane present
position.
 EFIS(electronic flight instrument system )— this system providesdisplays
of information from various airplane systems.
 WXR(weather radar) —this system provides a display of the weather
conditions forward of the airplane, and can also provide a map display.
 LRRA(low range radio altimeter)— this system measures the absolute
height of the airplane above the earth’s surface.
 GPWS(ground proximity warning system)— this system uses inputs from
other systems to navigatee the airplane and provide optimization of the
flight plan.
 FMCS(flight management computer system)— this system provides the
pitot with aural and visual warning of an unsafe flight path relative to the
earth’s surface.
 MKR BCN(marker beacon ) —this system provides an indication when
the airpnale is passing over a specific position.
 TCAS(traffic alert and collision avoidance system)— this system
provides the pitots with warnings and advisories of unsafe flight
conditions with regard to other airplanes operating in the area.
 导航系统计算并显示飞机的位置及其在地球表面的移动。导航系统包
括下列子系统：
 自动定向机——此系统提供一个相对一个选定的地面发射台的相对
方位角显示。
 甚高频全向信标/仪表着陆系统——此系统提供飞机相对于一个选定
的VOR 台的磁方位及飞机与预选航道的偏离显示信号。当转动仪表
着陆系统的频率时，此系统显示飞机与最佳着陆路径在水平及垂直方
向上的偏差。
 测距机—— 此系统用来测量飞机与选定的DME 设备的斜距。
 空中交通管制—— 此系统发射飞机识别码及高度信号给地面设备。
