Photography 15 hours on a Boeing Dreamliner, in coach Want to sit for 15 hours? Boeing's new claims better passenger comfort over extremely long-haul routes. Here's what it's like on one of the longest you can take.
Development Background During the late s, Boeing considered replacement aircraft programs as sales of the and slowed. The worst-affected airlines, those in the United States, had been considered the most likely customers of the Sonic Cruiser; thus the Sonic Cruiser was officially cancelled on December 20, On January 29, Boeing announced an alternative product, the 7E7, using Sonic Cruiser technology in a more conventional configuration.
This logo is painted on many s. The replacement for the Sonic Cruiser project was named "7E7"  with a development code name of "Y2". On April 26,Japanese airline All Nippon Airways ANA became the launch customer for theannouncing a firm order for 50 aircraft with deliveries to begin in late The final styling was more conservative than earlier proposals, with the fin, nose, and cockpit windows changed to a more conventional form.
Bycustomer-announced orders and commitments for the reached aircraft. This approach was intended to result in a leaner, simpler assembly line and lower inventory,  with pre-installed systems reducing final assembly time by three-quarters to three days.
Japanese industrial participation was key on the project. The variant was postponed to and the variant was to follow at a later date. However, on June 23,the first flight was postponed due to structural reasons. Certification cleared the way for deliveries and inBoeing prepared to increase production rates from two to ten aircraft per month at assembly lines in Everett and Charleston over two years.
A ceremony to mark the occasion was also held the next day. The Dreamliner then continued eastbound from Dhaka to return to Boeing Field, setting a world-circling speed record of 42 hours, 27 minutes. United Airlines is the North American launch customer for all three variants.
It could take up to 2 hours for the shaft to straighten again.
This was particularly acute on short haul flights as there was insufficient time to allow the unit to cool before a restart was needed. Procedures were modified and the APU was later redesigned to address the issue.
Employees did not fill gaps with shims to connect wing rib aluminum shear ties to the carbon composite wing panels; the tightened fasteners, without shims, cause excessive stress that creates hairline cracks in the wings, which could enlarge and cause further damage.
Forty-two aircraft awaiting delivery were affected, and each one required 1—2 weeks to inspect and repair. However, Boeing did not expect this problem to affect the overall delivery schedule, even if some airplanes were delivered late.
Daily utilization increased from five hours in to twelve hours in For example, Air Canada offered a Toronto to New Delhi route, first utilizing a Lockheed Lthen a Boeingthen an Airbus Abut none of these types were efficient enough to generate profit.
The airline operated the route profitably with aand credits the right number of seats and greater fuel efficiency for this success. Boeing plans to improve financial return by reorganizing the production line, renegotiating contracts with suppliers and labor unions, and increasing the production rate, stepwise, to 12 airplanes per month by the end of and 14 airplanes per month by the end of the decade.
The cost of producing the fuselage may increase because of a tentative deal reached with Spirit Aerosystems of Wichita, Kansaswherein severe price cuts demanded by Boeing would be eased, in return for a comprehensive agreement that lowers the cost of fuselages for other jetliners that Spirit helps Boeing manufacture.
Former Douglas Aircraft chief economist Adam Pilarski notes that two assembly sites slows the experience curve. Boeing assumed a faster improvement than on previous programs which has not happened. Airbus concurrence with the A and the launch of the Aneo put strong pressure on the pricing.
Boeing had planned to refurbish and sell them, but instead wrote them off as research and development expense.As is now the de facto standard on Boeing Dreamliner aircraft, the economy cabin is arranged with seating.
(Only a few airlines opted for the Boeing-recommended seating).
This arrangement necessitates a rather narrow inch seat. The United Airlines Boeing aircraft are some of the most technologically advanced aircraft flying.
The aircraft are generally used on international long haul routes. I flew on United's Dreamliner from San Francisco to Munich and back. As an overall impression of the Dreamliner, it is a very comfortable aircraft, even in Economy.

With more seating, smart technology, and innovative design, our new Dreamliner, along with its little sister the , are sure to transport you around the world in supreme comfort. In , the first year of service for the Boeing Dreamliner, a widebody jet airliner, at least four aircraft suffered from electrical system problems stemming from its lithium-ion urbanagricultureinitiative.comgh problems are common within the first year of a new aircraft design's life, after a number of incidents including an electrical fire aboard an All Nippon Airways , and a similar fire found.
