Airplanes which feature composite construction and have: a further aft than conventional center of gravity; a clean wing with a high aspect ratio; and all primary flight controls. These include trailing edge control segments (or elements) which extend the full span of the airplane wing. A central processor so schedules the upward and downward deployment of the control elements that: (1) downward and upward displacements of the control elements are respectively accompanied by pitch-up and pitch-down moments; (2) the inboard control elements are used primarily to change the coefficient of lift whereas roll control is effected principally by displacement of the outboard control elements; and (3) each of the control elements is individually displaced by a system which eliminates hydraulic systems and control cables. Hallmarks of these novel airplanes include simplicity, relatively low cost, lower weight, and safety.

A high efficiency airplane which comprises:
A method of scheduling the upward and downward movement of the control members of an airplane which has a body and a swept wing attached to said body and having an aspect ratio of 10 or more and a series of juxtaposed, hinged, control members at the trailing edge of said wing, the center of gravity of said airplane being on a line which passes through a point lying between 44 percent and 70 percent of the mean area chord of said swept wing, so that said control members at said trailing edge of said wing which are inboard and adjacent said body are forward of said center of gravity, in which method said control members are independently displaced and in which the displacement of said control members is so scheduled that:
