What is the primary purpose of the aircraft's primary flight controls?
Primary flight controls (ailerons, elevator, rudder) directly manage the aircraft's attitude and direction.
Which component is part of the aircraft's secondary flight controls?
Secondary flight controls (e.g., flaps, slats) augment lift or drag but are not essential for basic flight.
What material is commonly used in modern aircraft airframes for its strength-to-weight ratio?
Aluminum alloys are widely used due to their lightweight and corrosion-resistant properties.
What is the function of a wing spar?
The wing spar is the main structural member that carries flight loads.
Which system prevents ice buildup on the leading edges of wings?
De-icing systems (e.g., pneumatic boots, heated leading edges) remove ice during flight.
What is the purpose of the aircraft's horizontal stabilizer?
The horizontal stabilizer provides longitudinal (pitch) stability.

Which component transfers cockpit control inputs to the flight surfaces?
Control cables or fly-by-wire systems link pilot inputs to ailerons, elevators, etc.
What is a 'monocoque' aircraft structure?
Monocoque designs use the skin to bear primary loads, eliminating the need for a heavy internal frame.
Which inspection method is used to detect cracks in airframe structures?
Dye penetrant inspection reveals surface cracks invisible to the naked eye.
