Exam Questions and CORRECT Answers
Airfoil - CORRECT ANSWER - anything designed to provide lift when it moves through
the air
Fuselage - CORRECT ANSWER - main body of the plane; referred to as a truss or
monocoque
Stringer - CORRECT ANSWER - support structure that runs the length of the fuselage
Cantilever Wing - CORRECT ANSWER - has sufficient internal support structures to keep
it steady
Semi-cantilever wing - CORRECT ANSWER - requires additional support for the wing in
the form of external supports (bar connecting the fuelsage to the airfoil)
Flaps of Wing - CORRECT ANSWER - run from the fuselage to the middle of the wing;
adjust the lift and drag
Ailerons - CORRECT ANSWER - run from the middle of the wing to the edge;
responsible for the roll; joystick controls the roll
Wingspan - CORRECT ANSWER - distance from one wingtip to the other
Chord - CORRECT ANSWER - the distance from the leading edge (tip of wing closest to
the head of aircraft) to the trailing edge (tip of wing closest to the end of aircraft)
Camber - CORRECT ANSWER - curvature of the airfoil
, High Camber - CORRECT ANSWER - if the wing is heavily curved
Planform - CORRECT ANSWER - the shape of the wings when viewed from overhead
Swept wing - CORRECT ANSWER - provides better handling a high speeds but makes
the plane less stable at low speeds
Delta Wing - CORRECT ANSWER - triangular shape; enables the plane to travel but also
requires very high take-off and landing speeds
Tail Assembly - CORRECT ANSWER - also called empennage; includes vertical and
horizontal stabilizers, elevators, rudders, and trim tabs
Stabilizers - CORRECT ANSWER - fixed (non-adjustable) surfaces that extend from the
back end of the fuselage
Elevators - CORRECT ANSWER - are positioned along the trailing edges of the
horizontal stabilizers; the pilot can move the them to raise or lower the nose of the plane; control
planes pitch
Rudders - CORRECT ANSWER - connected to the trailing edge of the vertical stabilizer
and are used to move the nose of the plane to the left or right ; yaw; pedals
Trim tabs - CORRECT ANSWER - movable surfaces that extend off the trailing edges of
the rudder, elevators, and ailerons and are used to make smaller adjustments
Landing Gear - CORRECT ANSWER - consists of sets of wheels used for takeoffs and
landings; some planes have special non-wheel landing gear for water and snow; mainly
positioned at each wing or on the sides of the fuselage
