Boeing 747-8 subclass of Boeing 747
Design effort
On November 14, 2005, Boeing announced the launching of the 747 Advanced as the "Boeing 747-8". The 747-8 was the first lengthened 747 to go into production and the second 747 version with a fuselage of modified length after the shortened 747SP. The 747-8 was intended to use the same engine and cockpit technology as that of the 787, including the General Electric GEnx turbofan and fly-by-wire ailerons and spoilers. In 2006, Boeing said that the new design would be quieter, more economical and more environmentally friendly than previous versions of the 747. As a derivative of the already-common 747-400, the 747-8 has the economic benefit of similar training and interchangeable parts. Boeing firmed the 747-8 Freighter's configuration in October 2006.The 747-8, as a new development of Boeing's largest airliner, is notably in direct competition on long-haul routes with the Airbus A380, a full-length double-deck aircraft introduced in 2007. For airlines seeking very large passenger airliners, the two have been pitched as competitors on various occasions. Boeing states that the 747-8 is more than 10 percent lighter per seat and consumes 11 percent less fuel per passenger than the A380, translating into a trip-cost reduction of 21 percent and a seat-mile cost reduction of over 6 percent.Production of the first 747-8 Freighter began in Everett in early August 2008. On November 14, 2008, Boeing announced a delay to the 747-8 program, citing limited availability of engineering resources within Boeing, design changes and the recent strike by factory workers. In February 2009, only one airline customer (Lufthansa) had ordered the 747-8I passenger model, and Boeing announced that it was reassessing the 747-8 project. Chief executive Jim McNerney stated that continuation of the project was not a foregone conclusion, and that the company was assessing various options.
