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 787 was designed to be the first production airliner with the fuselage comprising one-piece composite barrel sections instead of the multiple aluminum sheets and some 50,000 fasteners used on existing aircraft. Boeing selected two new engines to power the 787, the Rolls-Royce Trent 1000 and General Electric GEnx. Boeing stated the 787 would be approximately 20 percent more fuel-efficient than the 767, with approximately 40 percent of the efficiency gain from the engines, plus gains from aerodynamic improvements, increased use of lighter-weight composite materials, and advanced systems.
On December 15, 2009, Boeing conducted the 787-8 maiden flight from Paine Field in Everett, Washington, at 10:27 am PST and landed three hours later at 1:33 p.m. at Seattle’s Boeing Field, after reaching 180 kn (333 km/h) and 13,200 ft (4,000 m).
The 6,800h, six-aircraft ground and flight test programme was scheduled in eight and a half months, the fastest certification campaign for a new Boeing commercial design.
The 787 made its first appearance at an international air show at the Farnborough Airshow, United Kingdom, on July 18, 2010.
The first 787 was officially delivered to All Nippon Airways (ANA) on September 25, 2011, at the Boeing factory. A ceremony to mark the occasion was also held the next day. On September 27, it flew to Tokyo Haneda Airport. The airline took delivery of the second 787 on October 13, 2011.
On October 26, 2011, an ANA 787 flew the first commercial flight from Tokyo Narita Airport to Hong Kong International Airport.
