Certification of the Boeing 787 Dreamliner



After much discussion and delays, U.S. and European authorities have certified the plane long-haul Boeing 787 Dreamliners. Recall that the first aircraft flight took place December 15, 2009. The latter is designed to carry between 210 and 330 passengers depending on configuration. The manufacturer has received approval from the Federal Aviation Administration in the U.S. (FAA) and European Aviation Safety Agency (EASA), the latter indicating that the device meets all the regulations in force.

The Japanese airline All Nippon Airways (ANA) for its previously announced it would take formal possession on September 25 of the first copy of the aircraft. It's about time! Since delivery will still be more than three years behind schedule, According to estimates by experts external to the builder, the project has incurred cost overruns of several billion dollars.

The construction of the Dreamliner is indeed a challenge to Boeing, the production process including making composite materials with the aim to reduce the device and reduce its fuel consumption.

However, composites do not follow the same laws as aluminum. If they have undeniable qualities, they are however not free from defects. The development of the wing and the point of attachment of the wing to the fuselage and have posed serious challenges to engineers. At present, the device has already been 827 orders. Boeing expects to produce ten copies per month by the end of 2013. United Continental Holdings, formed by the merger of Continental Airlines and United Air Lines, should receive its first Boeing 787 Dreamliner in early 2012; the assembly phase of the unit has already started in Everett, in the State of Washington.
