Fuel System Fundamentals Fuel System purpose - correct answer ✔✔Store, distribute, and control fuel to meet engine demand -Must work in normal and emergency situations -Perform operations Fuel System Perform operations for - correct answer ✔✔Refuel, Defuel, and Fuel transfer between tanks Components - correct answer ✔✔Fuel management panel, Fuel tanks or cells, Fuel pumps, Fuel Valves, Fuel Manifolds, Fuel filters, Heat Exchangers Fuel management panel - correct answer ✔✔-Centralized means of controlling fuel movement -Located in Pilot's compartment -Contains necessary switches and indicators -Tank Filler Caps Contains necessary switches and indicators to: - correct answer ✔✔1)Control and monitor individual engine fuel feed 2)Control tank-to-tank fuel transfer within the aircraft 3)Indicate quantity of fuel stored in fuel tanks 4)Alert the pilot of fuel system malfunctions with warning lights 5)Control / monitor air or ground refuel operations 6)Rapidly dump (release) fuel in emergency situations Fuel Tanks or Cells - correct answer ✔✔-Provide fuel storage -Vary in design, size, and shape based on aircraft Fuel Tanks or Cells Types - correct answer ✔✔Integral, Bladder, External, Integral - correct answer ✔✔-Built as part of the wing or fuselage (main body) structure -Tanks formed by sealing off structural areas with fuel resistant sealants Bladder - correct answer ✔✔-Installed in compartments called cavities -Can be made of rubber or nylon External - correct answer ✔✔-Attached to the aircraft exterior to extend aircraft range -May be jettisoned (dropped) from certain aircraft during combat or emergency situations Tank Filler Caps (provide access for) - correct answer ✔✔-Gravity (over--the-wing) refueling of individual tanks -Visual or dip stick checks of fuel quantity in tank -Secured in place with locking mechanism Fuel pumps - correct answer ✔✔-Provide necessary pressure to move fuel through the system plumbing -Pumps mounted in fuel tanks -Can transfer fuel from tank to tank Types of Pumps - correct answer ✔✔Boost pumps, Transfer pumps, Ejector pumps, and Booster pump Boost pumps - correct answer ✔✔Ensure positive fuel supply to engine driven pumps Transfer pumps - correct answer ✔✔Transfer fuel tank-to-tank Ejector pumps - correct answer ✔✔Operates by fuel being forced through a narrow area resulting in pressure reduction and velocity increase ( known as the Venturi principle ) to move fuel from tanks Booster pump and/ or Transfer pump can be - correct answer ✔✔Used to defuel a tank -Pressurization System Vent System - correct answer ✔✔-Routes air into or out of fuel tanks as it is displaced by fuel -Allows air to enter tanks to displace fuel being removed during engine operation, transfer, or defuel -Relieves effects of temperature / altitude changes on fuel and air in tank Pressurization System - correct answer ✔✔Provides emergency means of dumping fuel overboard in flight to lighten aircraft Fuel dump system - correct answer ✔✔-Provides emergency means of dumping fuel overboard in flight to lighten aircraft -A dump mast at the rear of the aircraft or on the wing trailing edge routes fuel overboard Fuel quantity indicating system - correct answer ✔✔Tank sensor/ Probe unit, Fuel quantity indicator, Total indicator, Indicator test switch, and Low pressure/ sump warning lights Tank sensor/ Probe unit - correct answer ✔✔-Electrically measures the amount of fuel in the tanks -Sends signal through a amplifier to fuel quantity indicator Fuel quantity indicator - correct answer ✔✔-Receives / decodes the signal from tank sensor / probe unit -Shows the amount of fuel in each tank -Indication provided in "pounds (lbs) of fuel" Total indicator - correct answer ✔✔Shows total amount of fuel in all tanks Indicator test switch - correct answer ✔✔Depressing test switch initiates a self-test of the indicator Low pressure/ sump warning lights - correct answer ✔✔- indicate fuel level/pressure is below required minimum - Located fuel management panel Refuel/ Defuel Methods - correct answer ✔✔Refuel Methods and Defuel Methods Refuel Methods - correct answer ✔✔Single Point Refueling (SPR) receptacle, Gravity (over-the wing), and In-flight refueling (IFR)/ Ariel Refueling receptacle Single Point Refueling (SPR) receptacle - correct answer ✔✔provides for rapid fueling of all tanks by connecting a hose to a quick disconnect single-point refueling receptacle (SPR) Gravity (over-the wing) - correct answer ✔✔Provides for individual tank filling through a tank filler cap In-flight refueling (IFR)/ Ariel Refueling receptacle - correct answer ✔✔Located to provide in-flight refueling access Defuel Methods - correct answer ✔✔Single point receptacle, Gravity, and Siphon Single point receptacle - correct answer ✔✔Provides for rapid defueling of all tanks by connecting a hose to a quick disconnect single-point receptacle (SPR) Gravity - correct answer ✔✔Provides for draining of individual tanks Siphon - correct answer ✔✔Provides for suctioning fuel out
