QUESTIONS AND CORRECT ANSWERS
fixed-wing aircraft structure - CORRECT ANSWERS✅✅1. Fuselage
2. Wings
3. Tail assembly or empennage
4. Landing gear
5. Powerplant
6. Flight instruments/controls and control surfaces
fuselage - CORRECT ANSWERS✅✅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 - CORRECT ANSWERS✅✅from which the pilots and the flight crew control the
aircraft's operations
Two design types of fuselage construction - CORRECT ANSWERS✅✅1. truss
2. monocoque
Truss construction fuselages - CORRECT ANSWERS✅✅use steel or aluminum tubing in a
series of triangular shapes (called trusses) to get the necessary strength and rigidity
monocoque designs - CORRECT ANSWERS✅✅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 - CORRECT ANSWERS✅✅airfoils attached to each side of the fuselage that serve as
the main lifting surfaces supporting the airplane in flight.
airfoil - CORRECT ANSWERS✅✅an aircraft part or surface (such as wing, propeller blade,
or rudder) that controls lift, direction, stability, thrust, or propulsion for the aircraft.
, monoplanes - CORRECT ANSWERS✅✅airplanes with one set of wings
biplanes - CORRECT ANSWERS✅✅airplanes with two sets of wings
cantilever wing - CORRECT ANSWERS✅✅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 - CORRECT ANSWERS✅✅requires both internal bracing and
external support from struts attached to the fuselage
ailerons - CORRECT ANSWERS✅✅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 - CORRECT ANSWERS✅✅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 - CORRECT ANSWERS✅✅the distance from the leading edge of the wing to the
trailing edge. Cuts the airfoil into an upper surface and a lower surface
mean camber line - CORRECT ANSWERS✅✅if we plot the points that lie halfway
between the upper and lower surfaces, we obtain a curve called the mean camber line.
camber - CORRECT ANSWERS✅✅the maximum difference between the the mean camber
line and the chord line. A measure of the curvature of the airfoil.
thickness - CORRECT ANSWERS✅✅the maximum difference between the upper and
lower surfaces
