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
