What is the primary purpose of an aircraft's hydraulic system?
Answer: Operate flight control surfaces
The hydraulic system is used to operate aircraft components like brakes, landing gear, and flight controls.
Which tool is commonly used to measure structural alignment in aircraft?
Answer: Plumb bob
A plumb bob is traditionally used to ensure vertical and horizontal alignment.
What is the most common material used for aircraft skin?
Answer: Aluminum alloy
Aluminum alloys are lightweight and corrosion-resistant, making them ideal for aircraft skins.
What component prevents an aircraft's structure from buckling under compressive loads?
Answer: Stringers
Stringers are structural elements that prevent buckling by reinforcing aircraft skin.
Which inspection method is best for detecting surface cracks on aircraft structures?
Answer: Dye penetrant inspection
Dye penetrant inspection is a popular method for identifying surface-breaking defects.
What is the main purpose of a pressurization system in an aircraft?
Answer: Maintain cabin pressure
Pressurization systems maintain safe cabin pressure at high altitudes.
What type of rivet is commonly used for aircraft assembly?
Answer: Solid rivet
Solid rivets are extensively used in aircraft structures for strength and reliability.
How often should aircraft control cables be inspected?
Answer: Every 100 hours
Control cables should be inspected periodically as prescribed by the manufacturer and FAA regulations, often every 100 flight hours.
Which tool is essential for checking the torque of aircraft fasteners?
Answer: Torque wrench
A torque wrench ensures that fasteners are tightened to the correct specifications.
