Its materials, listed by weight, are 50% composite, 20% aluminum, 15% titanium, 10% steel, and 5% other; the aircraft will be 80% composite by volume. Each 787 contains approximately 35 short tons of carbon fiber reinforced plastic (CFRP), made with 23 tons of carbon fiber. Aluminum is used on wing and tail leading edges, titanium used mainly on engines and fasteners, with steel used in various places. On the 787, Honeywell and Rockwell-Collins provide flight control, guidance, and other avionics systems, including standard dual head up guidance systems, while Thales supplies the integrated standby flight display and electrical power conversion system. A version of Ethernet (Avionics Full-Duplex Switched Ethernet (AFDX) / ARINC 664) will be used to transmit data between the flight deck and aircraft systems. The flight deck features LCD multi-function displays, all of which will use an industry standard GUI widget toolkit (Cockpit Display System Interfaces to User Systems / ARINC 661). The Lockheed Martin Orion spacecraft will use a glass cockpit derived from Honeywell International's 787 flight deck. Boeing 787 Dreamliner (wallpaper 4).

The 787 flight deck includes two head-up displays (HUDs) as a standard feature. Like other Boeing airliners, the 787 will use a yoke instead of a side-stick. The future integration of forward looking infrared into the HUD system for thermal sensing so the pilots can "see" through the clouds is under consideration. The risks of using a composite fuselage have been questioned by a former Boeing engineer, noting that carbon fiber, unlike metal, does not visibly show cracks and fatigue; the rival A350 was later announced to be using composite panels on a frame, a more traditional approach, which its contractors regarded as less risky. Further concerns include that, during crash-landings, survivable in metal planes, a composite fuselage could shatter and burn with toxic fumes. The porous properties of composite materials, allowing them to absorb unwanted moisture, have been questioned. As the aircraft reaches altitude, the moisture expands, and may cause delamination of the composite materials, and structural weakness over time. Boeing has dismissed criticisms of its fuselage materials, insisting that composites have been used on wings and other passenger aircraft parts for many years, and they have not been an issue. They have also stated that special defect detection procedures will be put in place to detect any potential hidden damage. Another concern arises from the risk of lightning strikes, with composite having as much as 1,000 times less electrical conductivity than aluminum, increasing the risk of damage. Boeing has stated that the 787's lightning protection will meet FAA requirements, and FAA management was planning to adjust some requirements, which will help the 787 show compliance. In summer 2010, a 787 experienced an in-flight lightning strike without damage. Boeing 787 Dreamliner (wallpaper 4). Boeing 787 Dreamliner aircraft images wallpaper gallery 4.
