When must the FUEL XFEED knob be set
to OFF?
For takeoff, go-around and landing flight phases
AOM 9-10-30 & AOM 2-36
Which MFD page provides a visual representation
of the fuel system operation and parameters?
The FUEL synoptic page (AOM 9-10-30)
What color does the total and individual tank
quantities and fuel temperature indications
indicate when in the normal operating range?
Green (AOM 9-10-30)

which aural warning is played twice?
“FUEL” (AOM 9-10-30)
Can fuel be transferred from one wing to another?
No (AOM 9-10-50)
How does the crossfeed valve allow corrections
in the event of a fuel load imbalance?
It allows both engines and/or the APU to be
fed by one tank (AOM 9-10-50)
Which CAS message is displayed on the EICAS
when the difference between the current and expected
fuel quantities is higher than 880 lb (400
kg) for 5 minutes?
The amber FUEL LEAK SUSPECTED CAS
AOM 9-10-50
How many fuel pumps does each fuel tank have?
Two DC fuel pumps (main (A) and backup (B))
and two scavenge pumps (AOM 9-10-50)
What controls the main (A) pump when the fuel
pump is in the AUTO position?
The engine ECU (AOM 9-10-50)
What controls the backup (B) pump when the fuel
pump is in the AUTO position?
The FCU (AOM 9-10-50)
List the four times when the backup (B) pump will
be automatically commanded on when the fuel
pump is in the AUTO position:
During engine start, APU start or run, fuel
low pressure detection, and when the main (A)
pump fails (AOM 9-10-50)
When will the amber FUEL WING IMBALANCE
CAS message be displayed
on the EICAS?

DEFUELING control panel located at?
In the forward portion of the right wing to fuselage
AOM 9-10-50
How long does the system pre-check on the
REFUELING/DEFUELING panel take to verify fuel
system operation?
Approximately 10 seconds (AOM 9-10-50)
Which switch located on the REFUELING/DEFUELING
control panel enables pressurized refueling
to be performed with the airplane energized
by either the APU/GPU or batteries power?
The POWER SELECTION switch (AOM 9-10-50)
