Fuel Flashcards
(27 cards)
When must the FUEL XFEED knob be set to OFF?

Which MFD page provides a visual representation of the fuel system operation and parameters?
The FUEL synaptic 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
When the total fuel quantity is displayed in red, which aural warning is played twice?
FUEL. AOM 9-10-30
Can fuel be transferred from one wing to the other?
No. AOM 9-10-50
How does the cross-feed 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. 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 back up (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 on the 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?
When the fuel imbalance between the tanks is higher than 510 pounds. AOM 9-10-500
Where is the pressure refueling point and REFULING/DEFUELING control panel located at?
Forward portion of the right wing 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 battery power?
The power selection switch. AOM 9-10-50
What should happen if the STOP REFUEL is displayed on the REFUELING/DEFUELING control panel during the
refueling process?
The process shall be halted manually by the operator by moving the refueling switch to the OFF position.
AOM 9-10-50
Can the tanks be refueled using the gravity refuel port on the top of each wing?
Yes. AOM 9-10-50
What are the two different methods that the airplane can be refueled?
By gravity or pressure. AOM 9-10-50
What are the two different methods that the airplane can be defueled?
By suction and/or pressure. AOM 9-10-50
Can the FWD and VRTL tanks in the Praetor 600 be refueled via gravity?
Yes, via refuel ports on the right hand side of each aux tank. AOM 9-10-50
How is fuel transferred from the FWD or VTRL tanks and where?
Automatically to both wings simultaneously. AOM 9-10-50
Can fuel be transferred from the FWD/VTRL tanks to each other?
No, only to the wings. AOM 9-10-50
If the AUTO function of the fuel panel for the FWD/VTRL tanks fail, how do we access the remaining fuel?
By selecting either FWD or VTRL on the FUEL TRANSFER panel. AOM 9-10-30
When is TRANSFER operations from the FWD or VTRL tanks not allowed?
During XFEED operation, takeoff, go-around and landing operations. AOM 9-10-50
