Aircraft Fuel Systems (1)

What is the primary purpose of the aircraft fuel system?

• • To provide power to the avionics

• • To supply clean, uncontaminated fuel to the engine

• • To increase the aircraft's speed

• • To manage electrical systems

Can you describe the basic components of an aircraft fuel system for a reciprocating engine?

• • Wings, rudder, landing gear

• • Fuel tanks, fuel lines, pumps, filters

• • Engine, propeller, wheels

• • Electrical wiring, batteries, spark plugs

How does a gravity-feed fuel system differ from a fuel pump system?

• • Gravity-feed uses natural force to move fuel, pump systems require a mechanical pump

• • Fuel pump systems work only in large aircraft

• • Gravity-feed systems use electric pumps for fuel flow

• • There is no difference between the two systems

What role does the fuel tank vent play in the fuel system?

• • It prevents fuel from freezing

• • It allows air to replace fuel used from the tank

• • It helps in filtering fuel before it enters the engine

• • It removes contaminants from the fuel

Why is it important to regularly check for water contamination in the fuel system?

• • Water can improve fuel efficiency

• • Water can cause engine failure

• • Water helps cool the engine

• • Water increases fuel flow

What is the function of a fuel strainer or filter in an aircraft fuel system?

• To mix fuel with air

• To prevent fuel from freezing

• To remove dirt and debris from the fuel

• To add additives to the fuel

Can you explain the purpose of a fuel primer in starting a reciprocating engine?

• • To cool down the engine before starting

• • To lubricate the pistons

• • To deliver fuel directly to the cylinders for easier starting

• • To clean the carburetor

How does carburetor icing affect fuel flow and engine performance?

• • It increases fuel flow and boosts power

• • It reduces fuel flow and can cause engine failure

• • It has no impact on fuel flow

• • It helps prevent engine overheating

What type of fuel is commonly used in reciprocating engines of small aircraft?

• Jet A

• Diesel

• AvGas

• Kerosene

What safety precautions should be taken when refueling a reciprocating-engine aircraft?

• • Keep the engine running to speed up refueling

• • Use only metal fuel containers

• • Ensure the aircraft is grounded to avoid static electricity

• • Stand inside the cockpit while refueling
