Overview The 757 is a low-wing cantilever monoplane with a conventional tail unit featuring a single fin and rudder. Each wing features a supercritical cross-section and is equipped with five-panel leading edge slats, single- and double-slotted flaps, an outboard aileron, and six spoilers. The wings are largely identical across all 757 variants, swept at 25 degrees, and optimized for a cruising speed of Mach 0.8 (). The reduced wing sweep eliminates the need for inboard ailerons, yet incurs little drag penalty on short and medium length routes, during which most of the flight is spent climbing or descending. The airframe further incorporates carbon-fiber reinforced plastic wing surfaces, Kevlar fairings and access panels, plus improved aluminum alloys, which together reduce overall weight by .
