In flight mechanics, the “angle of attack at the wing” refers to the angle between the chord line of the wing and the relative wind experienced by the wing. This angle is known as the “effective angle of attack” at the wing and is denoted as αw.
- αw: Effective angle of attack at the wing.
- α: Angle of attack of the aircraft (angle between the aircraft’s longitudinal axis and the oncoming airflow).
- iw: Angle of incidence, which is the angle between the chord line of the wing and the longitudinal axis of the aircraft.
