EICAS MESSAGES
EICAS messages are presented in the upper right corner of the EICAS
display. In case of a simultaneous failure in the EICAS and MFD
displays, the RMUs are capable of presenting some messages.
EICAS MESSAGES LEVELS
There are three message levels: warning, caution, and advisory:
− Warning messages are red colored and require immediate crew
action. Warning messages are always presented on the top of the
list, in the same order they are generated.
− Caution messages are amber colored and require immediate crew
awareness. They follow warning in criticality level and in display
presentation.
− Advisory messages are cyan and are dedicated to minor failures or
system status. Advisory messages are displayed below caution
messages.
A fourth level is provided for maintenance purposes, but it is not
presented to the flight crew, and its access can only be made on the
ground.
When the message is generated, it is displayed blinking at the top of
the associated group. To stop blinking, press the associated master
button on the glareshield. Advisory messages will stop blinking after 5
seconds.
EICAS MESSAGES PRIORITY LOGIC
If more than one message is simultaneously presented, warning will
precede caution messages, which will precede advisories. The space
is provided for the simultaneous display of up to 15 messages. An
END label is provided after the last message, to indicate end of
message listing. If more than 15 messages are being generated, a
knob in the display bezel permits paging through the remaining
messages. In this case, a status line is provided in the sixteenth line, to
indicate how many messages are not being currently presented and
where they are (above or below the currently presented messages).
END label and warning messages can not be scrolled out of the
display. Due to this characteristic, caution and advisory messages will
be scrolled in the area left blank below the warning messages. If a new
message is generated during a scrolling, it will be automatically
displayed at the top of the associated group.
