What does wing shape mean?
Wing shape means the shape of the wings, of which there are three main types. Straight, Swept-back and Delta. Straight wings are plain straight, and are stable, however, less aerodynamic. The Cessna Skywhawk is a good example. Swept-back is used on faster craft but sub-sonic and are used on craft such as the Boeing 737. The Delta wing is used for craft that fly above Mach 1, such as the Concorde or Space Shuttle.
