Air Foil
Ans: Cross sectional shape of a wing
Chord Line
Ans: Line from leading edge to trailing edge an airfoil (the wing).
Relative Wind
Ans: The direction of movement of atmosphere relative to an aircraft/airfoil. Opposes the
direction an aircraft is moving.
Leading edge
Ans: Tip of the wing (or airfoil)
Trailing edge
Ans: End of the wing (or airfoil)
Angle of attack
Ans: Angle between airfoil chord line and relative wind. changes with attitude and
direction of flight
Angle of incidence
Ans: Angle at which the wing is attached to the aircraft fuselage.
