The angle between the primary axis (usually the longitudinal axis) of a body moving through a fluid and the direction of fluid flow. The angle of attack affects both lift and drag. No angle of attack combines maximum lift and minimum drag. A zero angle produces minimum drag, but zero lift. Lift is increased as the angle of attack increases until a critical angle is reached when drag exceeds lift and the object stalls (see stall angle). See also lift:drag ratio.
