11,724 lbs (5,862 lbs per tank)
What is the maximum lateral fuel imbalance allowed between tanks in flight?
600 lbs
When are the auxiliary fuel pumps required to be selected ON?
Takeoff & Landing
or
primary pump failure
How many scavenge pumps are there in each wing?
4 in each wing
How many scavenge pumps are there on the aircraft in total?
8 (4 each wing)
T/F: The scavenge pumps are powered using motive flow.
TRUE
T/F: The APU fuel shutoff valve is controlled automatically by the fire protection system.
TRUE
If certain fuel information becomes invalid or unavailable, how is that indicated on the flightdeck?
White dashes replace digits or dials to indicated invalid/unavailable information
If any fuel quantity computer fails, what is used to determine the fuel quantity?
Magnastick (magnetic dipstick) on the underside of each tank
What quantity of fuel in the tank will cause the TANK FUEL LOW caution light to illuminate?
305 lbs (also changes fuel quantity pointers to amber)
T/F: Fuel can be transferred between tanks in flight.
TRUE (assuming AC power is available)
T/F: Fuel can be transferred between tanks on the ground.
TRUE (assuming AC power available)
When the inlet fuel temperature is in the normal range, what color is it displayed in on the ED?
White
When the inlet fuel temperature is below 0 degrees C, what color is it displayed in on the ED?
Amber (caution)
When the inlet temperature is above 71 degrees C, what color is it displayed in on the ED?
Red (warning)
Where is the REFUEL/DEFUEL control panel located?
2 (right) engine nacelle aft bottom panel
The fuel system is able to accomplish which of the following?
Storing Indicating Venting Feeding/scavenging Refuel/defuel Transfer
Which of the following is not a component of the fuel tanks?
Answer which IS a component of the fuel tanks
Main tank Surge bay Collector bay Flapper-type check valve Note: (Auxiliary tank is NOT a component)
The primary ejector pumps are powered by _____.
Motive flow (excess fuel not used by the FMU)
The purpose of scavenge pumps is to _____.
Draw fuel from low points in the main tank and deliver it to the collector bay to ensure collector bay is full of fuel at all times
If pilots needed to transfer fuel from Tank 2 to Tank 1, which AUX pump would be used?
Tank 2 Aux pump (because that is where the fuel is coming from)
If pilots needed to transfer fuel from Tank 1 to Tank 2, which AUX pump would be used?
Tank 1 AUX pump (because that is where the fuel is coming from)
T/F: With no power applied to the aircraft, the aircraft cannot be refuled.
FALSE, hot standby battery bus powers pressure refueling (also can do overwing refuel)
