Boeing 787 Dreamliner

The Boeing 787 Dreamliner is an American long-haul, mid-size widebody, twin-engine jet airliner made by Boeing Commercial Airplanes. Its variants seat 242 to 335 passengers in typical three-class seating configurations. It is the first airliner with an airframe constructed primarily of composite materials. The 787 was designed to be 20% more fuel efficient than the Boeing 767, which it was intended to replace. The 787 Dreamliner's distinguishing features include mostly electrical flight systems, raked wingtips, and noise-reducing chevrons on its engine nacelles. It shares a common type rating with the larger Boeing 777 to allow qualified pilots to operate both models.

The Boeing 787 Dreamliner is a long-haul, widebody, twin-engine jetliner, which features light-weight construction. The aircraft is 80 percent composite by volume;Boeing lists its materials by weight as 50 percent composite, 20 percent aluminum, 15 percent titanium, 10 percent steel, and 5 percent other.[183][184] Aluminum has been used throughout the wing and tail leading edges, titanium is predominantly present within the elements of the engines and fasteners, while various individual components are composed of steel.

External features include a smooth nose contour, raked wingtips and engine nacelles with noise-reducing serrated edges (chevrons). The longest-range 787 variant can fly 8,000 to 8,500 nautical miles (9,200 to 9,800 mi; 14,800 to 15,700 km), enough to cover the Los Angeles to Bangkok and New York City to Hong Kong routes. Its cruising airspeed is Mach 0.85, equivalent to 561 mph (903 km/h; 487 kn) at typical cruise altitudes. The aircraft has a design life of 44,000 flight cycles.
