The principal means to develop lifting force is the ram effect; lift is improved when flow underneath the wing body around stagnation point on the pressure surface (lower surface of body) is trapped. The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes) is its arrangement of lifting and related surfaces.

Aircraft designs are often classified by their wing configuration. For example, the Supermarine Spitfire is a conventional low wing cantilever monoplane of straight elliptical planform with moderate aspect ratio and slight dihedral.
