Fuel System Flashcards
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.
- Fuel transfer cannot take place.
Fuel tanks are vented to:
- The collector bay
- The surge bay
- The boost ejector pumps
- Dump valve
- The surge bay
Maximum main tank fuel imbalance is:
- 600 kg
- 1500 lb
- 600 lb
- Dependant on zero fuel weight
- 600 lb
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
- 130 lb in the associated collector bay
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.
- Air pressure from the ram-air inlets via the tank vent.
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.
- High-pressure return fuel from the HMU.
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.
- Two magna sticks, calibrated in USG and litres, the outboard being checked
if the inboard indicates full.
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.
- REFUEL or DEFUEL position is selected on the pressure refuelling control panel.
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.
- Manually, with the AUX PUMP switches, automatically when transferring fuel and automatically when de-fueling if AC ground power is available.
The main tank quantity is:
- 5678 imp gallons
- 5678 litres
- 5678 kg
- 5678 lb
- 5678 lb
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.
- Increase to full scale
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
- The master valve is closed
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.
- Six capacitance probes which are independent of the TANK FUEL LOW
caution system.
