Aviation Knowledge ACTUAL QUESTIONS
AND CORRECT ANSWERS
Airfoil - Correct answers✔✔A wing, helicopter blade, or propeller that generates more lift than
drag as air flows over its upper and lower surfaces
Angle of Attack - Correct answers✔✔The angle between the chord line of an airfoil and its
direction of motion relative to the air
Angle of Incidence - Correct answers✔✔(for fixed wing airplanes) The inclination of the wing
or tail surface relative to an imaginary line that is parallel to the aircraft's longitudinal axis
Anhedral Angle - Correct answers✔✔The downward angle of an airplane's wings and tail plane
from the horizontal
Attitude - Correct answers✔✔An aircraft's position relative to its three axis and a reference such
as the earth's horizon
Center of Gravity - Correct answers✔✔An aircraft's center of mass, the theoretical mass point
through which the entire mass of the aircraft is said to be concentrated
Chord - Correct answers✔✔The distance between the leading and trailing edges along the chord
line
Chord Line - Correct answers✔✔An imaginary straight line from the airfoil's leading edge to its'
trailing edge
, Constant Speed Propeller - Correct answers✔✔A controllable-pitch propeller whose angle is
automatically changed in flight by a governor in order to maintain a constant number of
revolutions per minute despite changing aerodynamic loads
Controllability - Correct answers✔✔A measure of an aircraft's response relative to flight control
inputs from the pilot
Controllable Pitch Propeller - Correct answers✔✔A propeller that can be varied in terms of its
blade angle by the pilot via a control in the cockpit
Coordinated Flight - Correct answers✔✔When the pilot applies flight and power control inputs
to prevent slipping or skidding during any aircraft maneuver
Critical Angle of Attack - Correct answers✔✔The Angle of Attack at which and airfoil stalls
(loses lift), regardless of speed, attitude, or weight
Dihedral Angle - Correct answers✔✔The upright angle of an airplane's wings and tail plane from
the horizontal
Dihedral Effect - Correct answers✔✔The amount of roll movement produced per degree of
sideslip
Directional Stability - Correct answers✔✔An aircraft's initial tendency about its yaw (vertical)
axis
Downwash - Correct answers✔✔Air that is deflected perpendicular to an airfoil's motion
