In fluid dynamics, angle of attack (AOA, α, or α {\displaystyle \alpha } ) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow.
