Version Graded A+
Explain the purpose of a static discharger on an aircraft.
✔✔ Static dischargers reduce the buildup of static electricity on the aircraft during flight,
preventing interference with communication and navigation equipment.
What is the function of an airspeed indicator?
✔✔ The airspeed indicator measures the aircraft's speed relative to the surrounding air, based on
pitot pressure and static pressure.
What is meant by the term "pressure altitude"?
✔✔ Pressure altitude is the altitude indicated when the altimeter is set to standard pressure
(29.92 in Hg), and it is used to determine performance in non-standard conditions.
Explain the purpose of a shock strut in an aircraft landing gear.
✔✔ A shock strut absorbs and dampens the impact of landing, ensuring a smoother touchdown
and reducing stress on the airframe.

,What is the purpose of safety wire in aviation?
✔✔ Safety wire is used to secure fasteners like bolts and nuts to prevent them from loosening
due to vibration.
Describe how the mixture control in an aircraft engine works.
✔✔ The mixture control adjusts the ratio of fuel to air entering the engine, allowing for efficient
combustion at different altitudes.
What is a wind correction angle, and why is it important?
✔✔ Wind correction angle is the angle you adjust your aircraft's heading to compensate for wind
drift, ensuring the aircraft stays on course.
Explain the purpose of an ELT (Emergency Locator Transmitter) in an aircraft.
✔✔ An ELT transmits a distress signal in the event of a crash, helping search and rescue teams
locate the aircraft.
What is a stall warning system, and how does it function?
✔✔ A stall warning system alerts the pilot when the aircraft is approaching a stall by detecting
the angle of attack and sounding an alarm or activating a light.
2
,Explain how fuel tank venting works and why it is necessary.
✔✔ Fuel tank venting allows air to enter the tank as fuel is consumed, preventing a vacuum from
forming that would restrict fuel flow.
What is the function of an aircraft's pitot tube?
✔✔ The pitot tube measures the dynamic pressure of the air, which is used to determine the
aircraft's airspeed.
What are the primary functions of the pitot-static system in an aircraft?
✔✔ The pitot-static system measures airspeed, altitude, and vertical speed by detecting pressure
differences.
Explain the purpose of a magneto in an aircraft engine.
✔✔ A magneto provides electrical power to the spark plugs, generating a spark for ignition in
the engine's cylinders.
What is the basic function of a carburetor in a reciprocating engine?
✔✔ The carburetor mixes air and fuel in the proper ratio for combustion.
3
, Describe the purpose of the hydraulic system in an aircraft.
✔✔ The hydraulic system operates components like landing gear, brakes, and flight controls by
transmitting force through fluid pressure.
What is meant by the term "absolute pressure"?
✔✔ Absolute pressure is the total pressure measured, including atmospheric pressure and any
additional applied pressure.
Explain why aircraft engines use a dual ignition system.
✔✔ A dual ignition system provides redundancy, increasing safety and ensuring more efficient
combustion by using two spark plugs per cylinder.
What is the purpose of a vacuum system in an aircraft?
✔✔ The vacuum system powers gyroscopic instruments like the attitude indicator and heading
indicator.
What is detonation in an aircraft engine, and why is it harmful?
