Questions and Answers 100% Pass
fixed-wing aircraft structure - ✔✔1. Fuselage
2. Wings
3. Tail assembly or empennage
4. Landing gear
5. Powerplant
6. Flight instruments/controls and control surfaces
fuselage - ✔✔body of an airplane. Contains the cockpit, the cabin, the cargo area if there
is one, and attachment points for other major airplane components, such as wings, tail
section, and landing gear.
cockpit - ✔✔from which the pilots and the flight crew control the aircraft's operations
Two design types of fuselage construction - ✔✔1. truss
2. monocoque
Truss construction fuselages - ✔✔use steel or aluminum tubing in a series of triangular
shapes (called trusses) to get the necessary strength and rigidity

, monocoque designs - ✔✔use bulkheads, stringers, (running the length of the fuselage)
and formers (perpendicular to stringers) of various sizes and shapes to support a
stretched or "stressed" skin
wings - ✔✔airfoils attached to each side of the fuselage that serve as the main lifting
surfaces supporting the airplane in flight.
airfoil - ✔✔an aircraft part or surface (such as wing, propeller blade, or rudder) that
controls lift, direction, stability, thrust, or propulsion for the aircraft.
monoplanes - ✔✔airplanes with one set of wings
biplanes - ✔✔airplanes with two sets of wings
cantilever wing - ✔✔requires no external bracing, getting its support from internal wing
spars, ribs, and stringers, as well as the construction of the wing's skin or covering
semi-cantilever wing - ✔✔requires both internal bracing and external support from
struts attached to the fuselage
ailerons - ✔✔extend from about the middle of the wing out toward the wingtip; they
move in opposite directions to create aerodynamic forces that cause the airplane to roll
flaps - ✔✔extend outward from near where the wing joins the fuselage (called the wing
root) to about the middle of the wing's trailing edge. The flaps are usually flush with the
rest of the wing surface when cruising flight; when they are extended, the flaps move
downward together to increase the lift of the wing for takeoffs and landings. Most
common high lift devices.
chord line - ✔✔the distance from the leading edge of the wing to the trailing edge. Cuts
the airfoil into an upper surface and a lower surface
