Answers Graded A+
What is the function of a hydraulic pump in an aircraft system?
✔✔To convert mechanical energy into hydraulic energy to pressurize the system.
What is the role of the accumulator in a hydraulic system?
✔✔To store hydraulic fluid under pressure for use when needed, ensuring smooth operation.
How does the aircraft’s anti-skid system function?
✔✔It prevents the wheels from locking during braking, improving safety and control.
What does the term "bleed air" refer to in an aircraft?
✔✔Air taken from the engine compressor used for cabin pressurization and other systems.
What is the primary purpose of a fuel control unit in an aircraft?
✔✔To regulate the flow of fuel to the engine to maintain optimal performance.

,Why is it important to check for leaks in the aircraft's fuel system?
✔✔To prevent fuel loss, ensure safety, and maintain system efficiency.
What is the main function of the aircraft's pitot tube?
✔✔To measure the airspeed of the aircraft by detecting dynamic pressure.
How does the aircraft’s electrical system function during flight?
✔✔It provides power for navigation, communication, lighting, and other essential systems.
What is the role of the aircraft's Environmental Control System (ECS)?
✔✔To maintain a comfortable and safe environment for passengers and crew by regulating
temperature, humidity, and air quality.
What is the primary purpose of an aircraft’s fire detection system?
✔✔To monitor for signs of fire in critical areas and alert the crew for emergency response.
Why are safety pins used in aircraft systems?
✔✔To prevent accidental deployment or activation of components during maintenance.
2
, What is the function of the aircraft’s autopilot system?
✔✔To control the flight path of the aircraft with minimal input from the pilot.
How does the aircraft’s landing gear system work?
✔✔It allows the aircraft to land, take off, and taxi by supporting the weight of the aircraft.
What is the purpose of the aircraft's anti-ice system?
✔✔To prevent the accumulation of ice on critical surfaces, ensuring safe flight operations.
Why is it important to check the aircraft’s oxygen system regularly?
✔✔To ensure a sufficient supply of oxygen is available in the event of cabin depressurization.
What is the function of an aircraft’s hydraulic fluid?
✔✔To transmit power in hydraulic systems, allowing for the operation of various flight
components.
