What is the primary purpose of a magneto in an aircraft engine?
✔✔The magneto generates electricity to ignite the fuel-air mixture in the engine, independent of
the aircraft’s battery.
Why is it essential to torque bolts in an aircraft engine to the manufacturer's specifications?
✔✔Proper torque ensures that the bolts are tight enough to hold components securely but not so
tight that they cause damage.
How does a carburetor work in an aircraft engine to maintain the correct fuel-air mixture?
✔✔The carburetor mixes fuel and air in the correct ratio, adjusting based on throttle input and
atmospheric conditions to optimize combustion.
Why are aircraft engines often equipped with dual ignition systems?
✔✔Dual ignition systems provide redundancy, ensuring that if one system fails, the engine can
still operate safely.

,What would happen if an engine’s oil pressure drops too low during flight?
✔✔Low oil pressure could lead to overheating, increased friction, and eventual engine failure.
Why is it important to inspect the propeller blades regularly for cracks or corrosion?
✔✔Cracks or corrosion can weaken the blades, potentially leading to catastrophic failure during
flight.
How does a turbocharger increase the performance of an aircraft engine?
✔✔A turbocharger compresses incoming air, allowing more oxygen into the engine for a more
powerful combustion, especially at higher altitudes.
What could cause an aircraft engine to "run rough" or misfire during flight?
✔✔Possible causes include a clogged fuel line, faulty spark plugs, or an incorrect fuel-air
mixture.
Why is it critical to check an aircraft's fuel system for water contamination before every flight?
✔✔Water in the fuel system can cause the engine to misfire or fail, as water does not burn like
fuel.

, How does the cooling system in an air-cooled aircraft engine prevent overheating?
✔✔Air is directed over the engine's fins, dissipating heat to prevent the engine from overheating
during operation.
What would happen if the alternator fails during flight?
✔✔The aircraft would lose its primary electrical power source, forcing it to rely on the battery,
which would eventually deplete.
Why do aircraft engines need a precise valve timing system?
✔✔Precise valve timing ensures that the fuel-air mixture enters and exits the engine cylinders at
the correct time for efficient combustion.
How does a fuel-injection system differ from a carburetor in an aircraft engine?
✔✔A fuel-injection system delivers fuel directly into the cylinders, providing more efficient and
consistent fuel distribution than a carburetor.
Why is it important to check for proper alignment of an aircraft’s control surfaces during
maintenance?
