Boeing 787 Dreamliner

The Boeing 787 Dreamliner is a long-range, mid-size wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. Its variants seat 210 to 290 passengers. Boeing states that it is the company's most fuel-efficient airliner and the world's first major airliner to use composite materials as the primary material in the construction of its airframe.[8] The 787 has been designed to be 20% more fuel efficient than the 767 it is to replace.[9][10] The Dreamliner's distinguishing features include mostly electrical flight systems, a four-panel windshield, noise-reducing chevrons on its engine nacelles, and a smoother nose contour. It shares a common type rating with the larger 777 twinjet, allowing qualified pilots to operate both models, due to related design features.[11] The aircraft's initial designation was 7E7, prior to its renaming in January 2005.[12] The first 787 was unveiled in a roll-out ceremony on July 8, 2007, at Boeing's Everett assembly factory, by which time it had reached 677 orders; this is more orders from launch to roll-out than any previous wide-body airliner.[13] By November 2012, the 787 program had logged 844 orders from 57 customers, with International Lease Finance Corporation (ILFC) having the largest number on order.[5] The 787 development and production has involved a large-scale collaboration with numerous suppliers around the globe. Final assembly is at the Boeing Everett Factory in Everett, Washington. Assembly is also taking place at a new factory in North Charleston, South Carolina. Both sites will deliver 787s to airline customers. Originally planned to enter service in May 2008, the project has suffered from multiple delays. The airliner's maiden flight took place on December 15, 2009, and completed flight testing in mid-2011. Final Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) type certification was received in late August 2011

nd the first model was delivered in late September 2011. It entered commercial service on October 26, 2011. The aircraft has suffered from early in-service problems, and is being reviewed by both the FAA and the Japanese aviation agency. On January 16, 2013, the FAA issued an emergency airworthiness directive that grounds all 787s in the U.S. The EASA, Japanese Transport Ministry, India's Directorate General of Civil Aviation (DGCA), and Chile's Direccion General de Aeronautica Civil (DGAC) followed suit and grounded the Dreamliners in their respective jurisdictions.[14][15] company proposed two new aircraft, the 747X, which would have lengthened the 747-400 and improved efficiency, and the Sonic Cruiser, which would have achieved 15% higher speeds (approximately Mach 0.98) while burning fuel at the same rate as the existing 767.[16] Market interest for the 747X was tepid, but the Sonic Cruiser had brighter prospects. Several major airlines in the United States, including Continental Airlines, initially showed enthusiasm for the Sonic Cruiser concept, although they also expressed concerns about the operating cost.[17] Earlier proposed design configuration of the Boeing 7E7. The global airline market was disrupted by the September 11, 2001 attacks and increased petroleum prices, making airlines more interested in efficiency than speed. The worst-affected airlines, those in the United States, had been considered the most likely customers of the Sonic Cruiser, and thus Boeing officially cancelled the Sonic Cruiser on December 20, 2002. Changing course, the company announced an alternative product using Sonic Cruiser technology in a more conventional configuration, the 7E7, on January 29, 2003.[8][18] The emphasis on a smaller midsize twinjet rather than a large 747-size aircraft represented a shift from hub-and-spoke theory towards the point-to-point theory,[19] in response to analysis of focus groups.
