What is a WARNING message?
WARNING (red): indicates an emergency or airplane system condition
that requires immediate corrective or compensatory crew action.
What is a CAUTION message?
CAUTION (amber): indicates an abnormal operational or airplane
system conditions that require immediate crew awareness and should
require a subsequent corrective or compensatory action.
What is an ADVISORY message?
ADVISORY (cyan): indicates operational or airplane conditions that
require crew awareness. Subsequent or future crew action may be
required.
What is a STATUS message?
STATUS (white): indicates information/status messages. The pilot can
use the system efficiently when the appropriate action is accomplished.
What does the Takeoff Configuration button push check?

Yes - more than 15 you can scroll using CCD knob. Can’t hide WARNING messages.
How do you know windshear escape guidance is shown?
WSHR in FMA. WSHEAR in red on PFD.
Activate if you get warning and press TOGA. GA-RSV if A/T on (if you shove to MAX you get GA-RSV).
What does it mean when an EICAS message has a chevron next to it?
EICAS messages which may generate more messages with them are
called Root EICAS messages and they are highlighted by a preceding
chevron “>”.
If more than one root message is displayed at the same time or
displayed together with a WARNING message, the priority order to be
evaluated is:
– WARNING messages;
– ELECTRICAL BUSES and;
– MAU.

What is the purpose of the scavenge ejector?
3 scavenge jet (ejector) pumps maintain the fuel level in the collector tank,
ensuring a constant flow of fuel to the engine during normal flight.
What is the primary purpose of the Main Ejector?
The primary wing fuel pump is a venturi ejector pump (jet pump) with
no moving parts, and is powered by the respective engine motive flow.
It is a self-sustained pump and does not require electrical power to
operate.
