Boeing B737 NG - Systems Summary [Warning Systems]
| | 原创/转载 | 转载 | | 语种 | 英文 | | 格式 | PDF | | 版本号 | 无 | | 大小 | 1.2M | | 描述 | 15.20 Warning Systems-System Description Introduction
Aural, tactile and visual warning signals alert the flight crew to conditions
requiring action or caution in the operation of the airplane. The character of the
signals varies, depending upon the degree of urgency or hazards involved. Aural,
tactile, and visual signals are used singularly or in combination to simultaneously
provide both warnings and information regarding the nature of the condition.
Mach/airspeed warnings, landing gear warnings, takeoff configuration warnings,
windshear warnings, and ground proximity warnings are discussed in this section.
Cabin altitude warning is discussed in this section and in the Air Systems briefing,
and autopilot and autothrottle disconnect warnings are discussed in the Automatic
Flight briefing. The conditions which excite the fire warning bell are discussed in
the Fire Protection briefing.
Conditions which require the immediate attention of the flight crew are indicated
by red warning lights located in the area of the pilots’ primary field of vision.
These lights indicate engine, wheel well, cargo, or APU fires; autopilot,
autothrottle disconnects; and landing gear unsafe conditions.
Conditions which require the timely attention of the flight crew are indicated by
amber caution lights.
Blue lights inform the flight crew of electrical power availability, valve position,
equipment status, and flight attendant or ground communications. Blue lights are
for information and do not require immediate flight crew attention. Some system
blue lights indicate a transitional state by illuminating bright as valves or
components reposition, then returning to a dim blue when the required
configuration is reached.
Green lights indicate a fully extended configuration, e.g., landing gear and leading
edge devices.
Stall warning is provided by a control column shaker on each control column.
Various aural signals call attention to warnings and cautions. An aural warning for
airspeed limits is given by a clacker, the autopilot disconnect by a warning tone,
takeoff configuration and cabin altitude by an intermittent horn, and landing gear
positions by a steady horn. The fire warning by a fire warning bell. Ground
proximity warnings and alerts, and windshear warnings and alerts are given by
voice warnings.
Generally, aurals automatically silence when the associated non–normal condition
no longer exists.
Master Fire Warning Lights
Two master FIRE WARN lights illuminate when any fire warning condition
occurs. The lights remain illuminated as long as the condition exists. Pushing
either master FIRE WARN light or fire warning bell cutout switch extinguishes
both lights, silences the fire warning bell and resets the system for future
warnings. Further information appears in the Fire Protection section.
Master Caution Lights
Two MASTER CAUTION lights illuminate when any caution occurs outside the
normal field of vision of the flight crew. The lights remain illuminated as long as
the caution condition exists, or until the crew resets the system. Pushing either
MASTER CAUTION light extinguishes both lights and resets the master caution
system for further cautions. Pushing either annunciator light panel recalls all
existing fault annunciations.
A single fault in certain redundant systems, or some simple faults, do not
illuminate the MASTER CAUTION or system annunciator lights. These faults,
however, are stored in the master caution system. Pushing the system annunciator
recalls the single fault on the system annunciator panel.
When the MASTER CAUTION recall is pressed, all twelve system lights should
illuminate while the press-to-test feature is held. If a system annunciator light does
not illuminate, refer to the dispatch deviation procedures guide (DDPG).
