VISUAL WARNINGS
Visual warnings are provided through lights, illuminated buttons,
EICAS messages and displays indications.
WARNING LIGHTS
Some of the airplane systems are actuated by illuminated buttons.
When under normal operating conditions, such buttons are not
illuminated. If the pilot has commanded the button to a position that
requires crew attention, a striped bar is illuminated inside the button.
There are some exceptions such as the windshield heating, the GPU,
the ice protection wing and stab, and the APU bleed buttons, which are
illuminated under normal operating conditions.
Some systems also provide indicating lights, for system status
indication. Further details on such lights are provided in the associated
systems description section.
Master warning and caution lights are installed on each pilot
glareshield panel. Such lights blink when any warning or caution
message is presented on the EICAS or generated in the Aural Warning
Unit (AWU). To stop blinking, pilots must press the associated light. To
find information on illuminated buttons and any specific warning light,
refer to the associated system’s description.
