Immediately cause the fire bottles to discharge
The yellow disk missing in a high rate discharge fire extinguishing system indicates:
Normal use
A thermal blowout
Either, normal or thermal discharge of the APU bottle
Either, normal or thermal discharge of the Engine bottle

There will be a question that uses this chart on the exam
True
False
There will be a question on the exam using this picture
True
False
The primary purpose of a fuel tank sump is to provide a:
Positive supply of pressurized fuel to the aircraft engine.
Means of separating out vapors from the fuel.
Reserve fuel supply
Place where water in the tank can collect & be drained
Why is it necessary to vent all aircraft fuel tanks?
Limit pressure differential between the tank and atmosphere.
The statement is false, fuel systems do not require a vent
To ensure a positive head pressure for submerged boost pump
Pressure refueled tanks do not need vents
Fuel system components must be bonded and grounded in order to:
To not allow static discharges to build up
Retard galvanic corrosion
Prevent stray currents
Provide power to the fueling truck/bowser
Which of the following is not a type of aircraft fuel valve?
A motor-operated centrifugal valve.
A solenoid-operated valve.
A manually operated poppet-type valve.
A motor-operated sliding gate valve.
The probe of a capacitance type fuel quantity transmitter is essentially:

A capacitor with fuel and air acting as a dielectric.
Can an aircraft only have an electric fuel pump & no engine-driven pump?
Never
Yes, if a gravity feed system for transfer or priming only
Yes, if the engine runs perfectly without the use of a pump.
Yes, but only for transfer of fuel from one tank to another.
