Compared with traditional panelized construction, one-piece barrel construction offers lower weight and reduced maintenance costs.Materials, aerodynamics, systems, and engines have been chosen and designed with the overall, integrated design at the forefront.
Design choices never optimize one area at the expense of overall performance, economics, maintenance costs, or airplane availability. New technologies are integrated while still maintaining a significant amount of commonality with other Boeing airplanes, particularly the 777. Familiar Boeing controls, displays and procedures all support shorter transition periods to the 787 from other Boeing family members, enabling efficient Mixed Fleet Flying. Dual Head-Up Display (HUD), very large flat panel multifunction displays, dual Electronic Flight Bags (EFB), and an electronic check list are provided as standard. Boeing 787 Dreamliner Interior Lighting Upgrade The DisplayAlso, the new displays are programmable, which means future advancements can be easily incorporated without having to replace or upgrade the display hardware. ![]() The electric system improves efficiency by extracting only the power actually needed during each phase of flight. The 787s electrical system also is monitored automatically by the Airplane Health Management system, improving airplane availability and productivity. This gives the airplane highly efficient lift-to-drag characteristics that reduce fuel consumption and costs. In addition, the 787s simple pivot trailing edge has fewer parts for reduced maintenance and provides a lighter and simpler high-lift system without sacrificing performance. This high aspect ratio wing design combined with efficiency enhancing raked wing tips allow the 787 to be one of the fastest commercial aircraft (Mach 0.85 cruise speed) while consuming less fuel than todays comparably sized aircraft. Instead of a mechanical system of cables and pulleys that move the control surfaces on the wing and tail, fly-by-wire systems translate pilot inputs into electrical signals. Computer processors translate these signals and move the control surfaces accordingly to move the airplane. Used on commercial airplanes for decades, fly-by-wire systems are highly reliable and feature multiple independent backup systems in case of a failure. ![]() Normally used to dip the wing up or down to turn in flight, ailerons on the 787 also adjust automatically to help optimize the wing during takeoff and cruise. This advanced fly-by-wire system also is the key to Smoother Ride Technology unique to the 787 family -- which senses turbulence and adjusts control surfaces automatically to dampen its effects before it reaches the passengers. This turbulence (or rough air) increases the power required by the engine, increasing fuel consumption. At the high speeds of commercial flight, this laminar flow is key because it reduces friction, which reduces drag, fuel consumption and emissions. Boeing 787 Dreamliner Interior Lighting Full Benefits OfBoeing expertise and the latest computational fluid dynamics (CFD) optimize engine and airframe integration, minimizing interference drag and capitalizing on the full benefits of these technological advances. This reduces not only weight and drag but also significantly reduces the amount of maintenance required. Pioneered by Boeing, one-piece barrel construction method is available only on the 787. This approach represents years of research and development by Boeing into the latest manufacturing processes.
