Empennage correct answers consists of the vertical stabilizer, rudder, horizontal stabilizer, hinge
elevator

Parts of plane correct answers fuselage, wings empennage

Flaps correct answers located on the trailing edge of the wing; increase wing's surface area and
deflect the air flow downward. Allow planes to lift at slower speeds.

Slats correct answers Flaps but on the leading edge of the wing

Spoilers correct answers hinged panels that move upward once landed; maximizes friction on
runway and deceleration.

Air brakes correct answers decelerate aircraft in flight and increase rate of descent. not designed
to destroy lift.

Spar correct answers the structural member inside of the wing runs the length

Shape Dribs correct answers attached perpendicular to the spare provides wing with more
structure and strength

Skin correct answers attaches all the framework

Swept back wings correct answers Used on jets to delay the drag associated with air
compressibility at high subsonic speeds

variable geometry wings correct answers pilot adjusts wings perpendicular to the fuselage during
low speeds (take off and landing) and back at high subsonic.

aileron correct answers hinged flight control surface on the outer trailing edge of each wing.
operate opposite each other in order to control rolling motion (performs banking turns)

trim tab correct answers on the rudder, elevator, and aileron reduces the need for the pilot to
apply constant pressure on the control column.

afterburner correct answers on tubojet engine; to increase thrust above afterburner full throttle

reverse thrust correct answers turbo prop; used to reduce runway distance of decelerating plane.
rotation of blades three to six to cause forward thrust. With jet engines, engine exhausts stop
from going aft and direct hot flow forward. (closed by buckets or clamshell doors

pivoting doors correct answers on the aft of the engines and direct the thrust forward.

, aerodynamic forces correct answers weight, lift, thrust, drag

center of gravity correct answers where the total force of weight acts on the aircraft

rolling correct answers turning left or right the amount of G increase
30 degrees - 16 percent more
60 degrees - 100 percent

G force correct answers increased by turbulent air
increased by flight path
increased by altitude.

Lift correct answers causes the machine to rise and become aloft; created by a pressure
differential between two surfaces results in an upward force on air foils.

Thrust correct answers aircraft's forward force

Drag correct answers opposes forward force caused by airflow over structure of plane; profile,
induced, parasitical

Profile drag correct answers sum of form drag and skin friction, Form: varies with air pressure
and cross-sectional shape
Skin: roughness of the outer surface of the air craft.

induced drag correct answers product of lift; increase in the air pressure differential between the
air foils forms a air vortex causing a retarding aerodynamic force. (increased from acceleration
or increased angle of attack).

parasite drag correct answers do not contribute to the production of lift but produce drag.
(landing gear)

Bernoulli's Principle and Lift correct answers L = 1/2 pv^2*ACi
p = fluid density
A airfoils area
Ci = coefficient of lift

Conservation of mass correct answers mass cannot be created nor destroyed

Conservation of momentum correct answers an object's mass times velocity cannot be created
nor destroyed.

Venturi effect correct answers pressure difference between the air foils creates the upward force
of lift

Unaccelerated flight correct answers weight = lift, thrust = drag
