That part of total drag caused by the same aerodynamic factors that produce lift. Vortex drag is dependent on the airfoil shape, its lift coefficient (CL2), velocity (1/V2), weight (W2), and aspect ratio (1/A). Also called induced drag.

To identify the origin of the reduction in drag the base, pressures are inferred from a vortex drag calculation based on the lift and drag.
