Fuel System

Question 1

When the FUELLING ON caution light in the cockpit is illuminated:

• Fuel transfer cannot take place.
• The pressure refuelling control panel access door is not closed.
• Refuelling is in progress.
• Defueling is in progress.

Answer 1

• Fuel transfer cannot take place.

Question 2

Fuel tanks are vented to:

• The collector bay
• The surge bay
• The boost ejector pumps
• Dump valve

Answer 2

• The surge bay

Question 3

Maximum main tank fuel imbalance is:

• 600 kg
• 1500 lb
• 600 lb
• Dependant on zero fuel weight

Answer 3

• 600 lb

Question 4

The TANK FUEL LOW caution light illuminates when the respective tank fuel level is less than:

• 130 US Gallons
• 130 lb in the associated collector bay
• 130 imperial gallons
• 130 kg in the associated fuel tank system

Answer 4

• 130 lb in the associated collector bay

Question 5

Fuel in the surge bay is returned to the main tank by the following means:

• Air pressure from the ram-air inlets via the dump valve.
• Gravity flow.
• The fuel scavenge system.
• Air pressure from the ram-air inlets via the tank vent.

Answer 5

• Air pressure from the ram-air inlets via the tank vent.

Question 6

Motive-flow fuel for the scavenge system is provided from:

• The auxiliary fuel boost pump.
• The auxiliary fuel boost pump overflow.
• High-pressure return fuel from the HMU.
• A fuel scavenge ejector pump in each main tank.

Answer 6

• High-pressure return fuel from the HMU.

Question 7

Each main tank is fitted with:
- Two magna sticks, calibrated in Ibs & kgs, the outboard being checked if the
inboard indicates full.
- Two magna sticks, calibrated in USG and litres, the inboard being checked if
the outboard indicates full.
- Two magna sticks, calibrated in Ibs & kgs.
- Two magna sticks, calibrated in USG and litres, the outboard being checked
if the inboard indicates full.

Answer 7

• Two magna sticks, calibrated in USG and litres, the outboard being checked
  if the inboard indicates full.

Question 8

Illumination of the FUELLING ON caution light in the cockpit indicates that:
- Refuelling is complete, and all switches are properly positioned for flight.
- Refuelling pressure has exceeded the maximum allowable.
- Auxiliary fuel transfer is taking place
- REFUEL or DEFUEL position is selected on the pressure refuelling control
panel.

Answer 8

• REFUEL or DEFUEL position is selected on the pressure refuelling control panel.

Question 9

The auxiliary fuel boost pumps can be turned on by the following methods:

• Manually, with the AUX PUMP switches, automatically when transferring fuel and automatically when de-fueling if AC ground power is available.
• Manually, with the AUX PUMP switches.
• Automatically when de-fueling if AC ground power is available.
• Automatically when transferring fuel.

Answer 9

• Manually, with the AUX PUMP switches, automatically when transferring fuel and automatically when de-fueling if AC ground power is available.

Question 10

The main tank quantity is:

• 5678 imp gallons
• 5678 litres
• 5678 kg
• 5678 lb

Answer 10

• 5678 lb

Question 11

The QTY TEST push button, when pressed, causes the fuel gauge pointers to:

• Calibrate to 5678.
• Calibrate to 100.
• Decrease to empty.
• Increase to full scale.

Answer 11

• Increase to full scale

Question 12

Illumination of the MASTER VALVE CLOSED advisory light on the pressure refuelling control panel indicates that:
- Power is on the refuelling / de-fuelling system, and the panel is set to initiate
either refuelling or de-fuelling.
- Refuelling is in progress
- The master valve is closed
- The master valve is open

Answer 12

• The master valve is closed

Question 13

The electrical fuel tank contents indicators are powered by:
- Six capacitance probes which are independent of the TANK FUEL LOW
caution system.
- The refuelling bay fuel indicators.
- The DC powered magna sticks.
- Six capacitance probes, which also signal the TANK FUEL LOW annunciator.

Answer 13

• Six capacitance probes which are independent of the TANK FUEL LOW
  caution system.
