On a piston engine aircraft, a filter is installed in the fuel system to..
  • A
    remove particles and impurities from the fuel that could damage the engine.
  • B
    store a small amount of fuel under a certain pressure.
  • C
    extract the water from the fuel.
  • D
    allow a person to take a sample of the fuel and to empty the fuel tank for maintenance.

FILTERS. Although all fuel is filtered to a high standard immediately prior to being dispensed into the aircraft, there remains a likelihood that debris may enter the fuel either through the tank vents, from residual deposits in the tanks or through open line refuelling points. All aircraft fuel systems have filters to ensure that the fuel delivered to the engine is free from contaminants.
