EICAS Messages
Systems conditions and configuration information is provided to the crew by four
types of EICAS messages:
• EICAS alert messages are the primary method to alert the crew to
non-normal conditions
• EICAS communication messages direct the crew to normal
communication conditions and messages
• EICAS memo messages are crew reminders of certain flight crew selected
normal conditions
• EICAS status messages indicate equipment faults which may affect
airplane dispatch capability
An EICAS alert, communications, or memo message is no longer displayed when
the respective condition no longer exists.
EICAS Alert Messages
From after engine start until engine shut down, EICAS alert messages are the
primary means to alert the crew to non-normal conditions which may impact other
operations during the flight.
There is a non-normal procedure for each EICAS alert message. The procedure for
every EICAS alert message is included as a checklist in the QRH. Procedures for
some EICAS alert messages have steps to reconfigure airplane systems. A
rectangular symbol [] prefaces an alert message that has procedural steps. The
rectangular symbol [] also prefaces EICAS alert messages for checklists that have
notes or information of which the crew must be made aware.
EICAS alert messages are grouped into three priority levels: warning, caution, and
advisory. Prioritization is an aid to flight crew decision making when more than
one EICAS alert message is displayed.
EICAS warning messages are displayed red and EICAS caution and advisory
messages are displayed amber. Red EICAS alert messages remain displayed and
cannot be canceled by pushing the CANC/RCL switch. Amber EICAS alert
messages can be canceled and recalled by pushing the CANC/RCL switch.
EICAS Communication Messages
EICAS communication messages direct crew attention to normal communication
conditions which may require crew attention. There is a crew action for each
EICAS communications message.
EICAS communications messages are grouped into three priority levels: high,
medium, and low. Prioritization is an aid to flight crew decision making when
more than one message is displayed.
