What is the purpose of an aircraft's hydraulic system?
✔✔The hydraulic system is used to power flight control surfaces, landing gear, and brakes with
fluid pressure.
How do you identify a faulty alternator in an aircraft?
✔✔A faulty alternator can be identified by a low or fluctuating voltage reading on the electrical
system's indicator.
What material is commonly used for aircraft skin, and why?
✔✔Aluminum is commonly used for aircraft skin because it is lightweight, corrosion-resistant,
and strong.
What is the function of a fire detection system in an aircraft?
✔✔The fire detection system monitors critical areas for signs of overheating or fire and alerts the
pilot.

,How do you determine if an aircraft's tires need replacement?
✔✔Tires should be replaced if there is excessive wear, cracks, cuts, or if tread depth is below
recommended levels.
What is a servo tab, and how does it help in flight control?
✔✔A servo tab is a small, adjustable surface on a control surface that reduces the control force
needed by the pilot.
What is the main purpose of an aircraft's landing gear system?
✔✔The landing gear supports the aircraft during takeoff, landing, and while on the ground.
What precautions should be taken when working around aircraft propellers?
✔✔Always approach propellers from behind, never touch them unnecessarily, and ensure the
engine is off and secure.
Explain the difference between a fixed and retractable landing gear.
✔✔Fixed landing gear remains in position during flight, while retractable gear can be stowed to
reduce drag.
2
,What is an anti-skid system, and how does it enhance safety during landing?
✔✔The anti-skid system prevents wheel lock-up by modulating brake pressure, improving
control during landings.
What are the risks of operating an aircraft with ice accumulation on the wings?
✔✔Ice accumulation can disrupt airflow over the wings, leading to a loss of lift and potential
stall.
What is the function of static wicks on an aircraft?
✔✔Static wicks discharge static electricity accumulated on the aircraft, reducing radio
interference and ensuring safe operation.
What is the primary function of the aircraft battery?
✔✔The battery provides electrical power for engine starts and supplies power during a failure of
the generator.
How do you perform a pre-flight inspection on an aircraft?
✔✔A pre-flight inspection includes checking the fuel, oil, control surfaces, and general
condition of the aircraft.
3
, What does the term "center of gravity" refer to in aviation?
✔✔The center of gravity is the point where the aircraft's weight is evenly distributed in all
directions.
Describe the purpose of a flight control system.
✔✔The flight control system allows the pilot to manipulate the aircraft's pitch, roll, and yaw
during flight.
What is the significance of an aircraft’s airworthiness certificate?
✔✔The airworthiness certificate indicates that the aircraft meets all safety standards and is safe
to fly.
Explain how the pitot-static system functions.
✔✔The pitot-static system measures airspeed, altitude, and vertical speed by using atmospheric
pressure differences.
What safety checks should be done before operating an aircraft?
