A combination of these technologies, along with supercritical wings, composites and artificially stable control systems would improve fuel economy of future airliners by 60%.

If the area rule was Whitcomb's major accomplishment of the 1950s, his supercritical wing revolutionized the design of jet liners in the 1960s.

The idea was to design an executive aircraft which would bring together a supercritical wing with Lycoming's new turbofan engine.

The Challenger was also one of the first bizjets designed with a supercritical wing.

Combined with the supercritical wing developed from Dornier's Do 228, this gave the 328 excellent cruise and climb capabilities.

The supercritical airfoil shape is incorporated into the design of a supercritical wing.

Consequently, aircraft utilizing a supercritical wing have superior takeoff and landing performance.

This makes the supercritical wing a favorite for designers of cargo transport aircraft.

The resulting design includes an area-ruled fuselage for efficient transonic flight, and the aforementioned highly swept supercritical wing.
