Angle of attack is best described as the angle between which two references?

Choices

  • ✓ The chord line of the wing and the relative windcorrect

    Angle of attack is defined between the chord line and the relative wind.

  • The longitudinal axis and the horizon

    That describes pitch attitude, not angle of attack.

  • The flight path and the horizon

    That describes the climb or descent angle, not angle of attack.

  • The wingspan and the fuselage

    This is not a definition of angle of attack.

Why

Angle of attack is the angle between the wing chord line and the relative wind, and it is distinct from pitch attitude and flight-path angle.
