02_02. Aircraft Structures and Components

What is the purpose of the airfoil shape in wings?

• To store fuel

• To create lift as air moves faster over the top

• To control the roll of the aircraft

• To increase drag

What do ailerons and flaps on wings allow for?

• Fuel storage

• Increased drag

• Roll control and increased lift during takeoff and landing

• Decreased lift

Why do many aircraft store fuel within the wings?

• To create lift

• To control the roll of the aircraft

• To utilize space efficiently and balance the plane's weight

• To increase drag

What is the primary function of spars in wing construction?

• To give the wing its airfoil shape

• To form the wing's aerodynamic surface

• To provide primary structural support

• To house the fuel tank

What role do ribs play in wing construction?

• They run from the fuselage to the wing tip

• They give the wing its airfoil shape and distribute loads

• They form the wing's aerodynamic surface

• They house the fuel tank

What material is typically used for the skin of a wing?

• Wood

• Steel

• Aluminum or composite materials

• Plastic

What is the primary function of the fuselage in commercial aircraft?

• To house passengers, crew, and cargo

• To control the aircraft's direction

• To provide lift for the aircraft

• To store fuel for the engines

What is the fuselage designed to withstand during flight?

• High temperatures

• Pressure differences and aerodynamic forces

• Water pressure

• Electrical surges

Which systems run through the fuselage, connecting various aircraft components?

• Fuel and cooling systems

• Electrical, hydraulic, and control systems

• Navigation and communication systems

• Propulsion and landing gear systems

Which fuselage construction method involves a shell-like structure where the skin bears the primary loads?

• Monocoque

• Semi-monocoque

• Space frame

• Truss
