A wing is described which constitutes a roll control device for aircraft of cropped, arrow-type planform with thin leading and side edges, having a pivotable tip to alter the crop angle of the wing during flight. Increasing the crop angle causes the wing side edge to become a trailing edge thereby reducing the wing surface area which the leading edge and side edge shed vortex systems can act against. This reduction also diminishes the strength of the shed vortex system. Decreasing the crop angle causes opposite results.
