EICAS communications messages are displayed in white below EICAS alert
messages. Communication messages can not be cancelled by pushing the
CANC/RCL switch.
EICAS Memo Messages
EICAS memo messages are crew reminders of certain flight crew selected normal
conditions. They are displayed in white at the bottom of the last page of EICAS
alert messages on the primary EICAS display.
Pushing the CANC/RCL switch when the last page of EICAS alert messages is
displayed ensures all current memo messages have been displayed.
EICAS Status Messages
All EICAS status messages are listed in the Dispatch Deviation Guide (DDG) or
airline equivalent and provide a cross reference to the Minimum Equipment List
(MEL) for dispatch capability.
Display and Manipulation of EICAS Messages
If more than one EICAS alert message is displayed, the messages are displayed in
a list which is grouped by priority level. EICAS warning messages are displayed
in red at the top of the message list.
EICAS caution messages are displayed in amber below the lowest warning
message. EICAS advisory messages are displayed in amber below the lowest
caution message and are indented one character so they may be distinguished from
EICAS caution messages.
The most recent EICAS alert message is displayed at the top of its priority group
and all messages move down one display line. If a message is no longer displayed
because the respective system non-normal condition no longer exists, all messages
previously displayed move up one display line.
If there are more messages in the list than can be displayed on one page, multiple
pages are created and numbered sequentially. The page number is normally
displayed at the bottom of each list. Multiple pages of EICAS caution and
advisory messages can be displayed one page at a time by pushing the
CANC/RCL switch. If there are more EICAS warning messages in the list than
can be displayed on one page, no page number is displayed and it is not possible
to display other pages. In all other cases, pushing the CANC/RCL switch displays
the next page of EICAS caution and advisory messages. EICAS warning
messages are displayed at the top of each page.
Pushing the CANC/RCL switch when the last page of the list is displayed causes
all EICAS caution and advisory messages to be no longer displayed.
EICAS alert messages for new system non-normal conditions are displayed on the
page being viewed.
