Abstract

An aircraft having a fuselage and a wing employs area-ruling of the fuselage in a vertical direction, with at least a substantial amount of the area-ruling being accomplished by dishing the keel area of the fuselage directly below the center portion of the wing. In one embodiment the aircraft has a main passenger seating deck and forward and aft upper seating decks located above the main deck respectively forward and aft of the wing, and both the upper surface of the fuselage above the wing and the lower surface of the fuselage below the wing are area-ruled.
