Ето и статията в Flightglobal. Добре изглежда :smt037

Най-хубавата част от всичко са GEnx-овете. Заедно със новото крило трябва да свалят разхода на гориво с 16% :smt030 :idea:

Нямам търпение да се кача на един 747-8 през 2012, стига Луфтханза да ги получи на време.

FAA tells Boeing to fix 747-8 software to avoid crash
Administration on Tuesday ordered an immediate fix to the latest version of Boeing Co's 747-8 plane, saying a software glitch could cause it to lose thrust when close to landing and fly into the ground.The FAA's so-called airworthiness directive covers Boeing's 747-8 and 747-8F planes with certain General Electric Co engines. It calls for replacing defective software with a new, improved version.The rule, the fourth such directive involving the 747-8, directly affects seven airplanes in the United States, the FAA said.If adopted internationally, the rule would cover a larger number. Boeing's website said it had delivered 66 of the four-engine jets, the company's largest, to customers worldwide since the model was introduced in October 2011.The problem never caused a problem in flight, Boeing said.Because of the seriousness of the safety issues, the directive takes effect April 9, skipping the usual comment period, although comments can still be submitted, the FAA said.Boeing said data analysis indicated a potential problem, and it advised customers last year to update the software. It said it believed the majority of operators had already done so.The risk of failure was "extremely remote," Boeing said.GE said it owned the software and jointly analyzed it with Boeing, but plane maker decided to recommend the software change to customers.According to the FAA, the risk arises when a plane is changing back into "air mode" while performing a "rejected or bounced landing." That change halts hydraulic pressure used to stow the engine thrust reversers, which slow the plane on landing, the agency said.Without hydraulic pressure, the reversers may not stow fully and might redeploy, which "could result in inadequate climb performance at an altitude insufficient for recovery, and consequent uncontrolled flight into terrain," the FAA said. Unidentified business jet/VIP customers own the eight passenger models of the aircraft in the United States, according to Boeing's website. Air cargo company Atlas Air is the largest U.S. commercial owner of the jet, with a fleet of eight 747-8F freighters.Among passenger carriers, Lufthansa is the largest operator, with 11. An airline spokesman said it had been informed of the directive and was checking to what extent its fleet of 747-8s was affected. He added the group was also considering its response to the FAA.China's Cathay Pacific <0293.HK> has 13 freighters and Cargolux, based in Luxembourg, has nine.Korean Airlines Co <003490.KS>, Nippon Cargo Airlines Co Ltd and Volga-Dnepr UK Ltd also own 787-8F freighters, according to Boeing's website.Shares of Boeing were up 0.5 percent at $124.01 in afternoon trading.

Japan to bid farewell to 747 'jumbo'
Japanese plane buffs will say a fond farewell to the "jumbo jet" this month as the Boeing 747 makes its final scheduled flight in the country.The two-deck carrier, loved for its broad-shouldered look, will ferry holiday-makers and aviation enthusiasts on an All Nippon Airways flight from Naha, in Okinawa, to Tokyo's Haneda airport on March 31.The jumbo jet -- 70 metres (229 feet) long and 60 metres wide -- was first introduced to the country by Japan Airlines (JAL) in 1970 and became a workhorse on both domestic and international routes.At one time Japanese airlines owned more than 120 of them, each capable of carrying over 500 passengers, the Mainichi Shimbun daily reported.But as well as its place in Japan's affections, the 747 is also remembered for its involvement in the nation's worst ever aviation accident and the deadliest single-aircraft disaster in history.In 1985, JAL Flight 123, flying from Tokyo to Osaka with 524 people aboard, crashed 120 kilometres (75 miles) northwest of Tokyo, killing all but four people on board.The jumbo jet has been replaced by more fuel-efficient models, most notably the lightweight 787 Dreamliner, the first mid-sized plane able to fly long-haul.The 747 is still in use in other countries around the world.
