20 Questions5 MinutesCreated by FlyingFalcon47

Which manifold is used during rapid defueling ?

Refueling, defuel transfer valve and crossfeed manifold

Refueling and jettison manifold

Only defueling manifold

Crossfeed, defueling and jettison manifold

How is the refueling valve energised during a refueling operations?

Plunger retracted by the energised solenoid causes a drop in the floats thereby opening the pilot valv

Solenoids energises to retract plunger causing the float to rise and open valve

Float switch energised to open causing the pilot valve to open

Float valves energises to drop in fuel level, than causing the float to rise and open the pilot valve.

JP5 Fuel is safer than the other types of fuel because

The flash point is higher

The flash point is lower

The freezing point is higher

The boiling point is lower

The high level indication light comes on during pressure refueling when

All tanks are full

The transverse tank is full

The aft tank is full

The feedertank is full

Microbiological growth is the fuel system can be prevented by

Adding FSII element into the fuel system

Increasing the fuel tank pressure

Increasing the flash point of the fuel

Eliminate the water in the fuel system

The dielectric in a tank unit varies with

Fuel quantity

Temp

Volume of fuel

Density of fuel

For fighter aircrafts, what is used to pressurize the external fuel tanks for fuel transfer

Engine bleed air

Pressure regulator

Boost pump

Fuel pump

How does fighter a/c internal fuel cells vent the air out

Each fuel cell vent out the air into common vent line to the fin

Engine bleed air supplied to the external fuel system assist in venting

The internal fuel cells

All fuel cells vent out the air into the common vent line below the fuselage

Which of the following component is used to drain out the fuel completely from the tank after defuelling operation has been completed?

Dump pump

Boost Pump

Water Drain Valve

Jet Pump

How is the fuel from the external tanks of a fighter a/c fuel system supplied to the engine ?

Bleed air is used to force fuel out of the external tank into the internal fuel systems and subsequently feed to the engines thru the boost pumps

Fuel flows into the engine by gravity

Using fuel boost pump in all tanks

By means of bleed air supplied to external tanks and fuel booster pump in the internal fuel system to suck fuel in

The function of a high level sensor in a fuel tank is to

Prevent overfilling of the tank

Indicate the max level of the fuel in the tank

Prevent fuel from leaking during inverted flight

Ensure the wing tanks are topped up at the same rate

Which is the following is NOT caused by water in the fuel system?

Fuel vapor in the fuel line

Erratic fuel quantity indications

Ice formed on fuel lines

Engine flameout an corrosion in the fuel component

Which fuel tank cannot be removed from the a/c

Integral tank

Pylon tank

Bladder tank

Rigid tank

What prevents excessive surge pressure from being exerted on the end bulkheads of the integral fuel tank during wing-down or slide slip maneuvers?

Vents

Crossfeed valve

Baffles

Filler port

Which of the following is used to control the a/c refueling operations ?

Dump pump

Single point adapter

Refueling control panel

Fuel boost pump

Which is NOT the purpose of fuel vent system ?

Reduce fuel vaporization at high altitudes

Prevent ambient air from entering the tank

Allow air to escape from the tank

Prevent over pressure and negative pressure

The internal fuel system for fighter a/c consist of 3 rubber impregnated nylon fabric bladder tank installed in the a/c fuselage called

Bladder tank

Wing tank

Fuselage tank

Fuel cell

What is the advantage of AVGAS Fuel ?

Low fuel consumption rate

Richer air/fuel mixture

Improve engine power

Easier to start the engine

In a typical helicopter fuel system, what is the function of the jet pump?

Transfer fuel from other tanks into the feeder tank

Transfer fuel from LH Tank to RH Tank

Transfer fuel from RH Tank to LH Tank

Transfer fuel from feeder tank to the engine
