Questions and Answers

Which one of these is true about camber?

  • Camber refers to the curvature of an airfoil above and below the chord line surface. (correct)
  • Camber refers to the curvature of an airfoil on the leading edge.
  • Camber refers to the curvature of an airfoil only below the chord line surface.
  • Camber refers to the curvature of an airfoil only above the chord line surface.

    • What is the angle of incidence?

  • The angle between the chord line of the wing and the mean line of the section.
  • The angle between the chord line of the wing and the center of pressure.
  • The angle between the chord line of the wing and the longitudinal axis of the aircraft. (correct)
  • The angle between the chord line of the wing and the direction of the relative wind.

    • What is the angle of attack (AOA)?

  • The angle between the chord line of the wing and the longitudinal axis of the aircraft.
  • The angle between the chord line of the wing and the center of pressure.
  • The angle between the chord line of the wing and the direction of the relative wind. (correct)
