Al di la dell'anno fiscale, secondo me si riferiscono alla fine della winter season, ovvero l'ultima domenica di Marzo.
Quest'anno cade proprio il 31 Marzo.

Japan's All Nippon Airlines (ANA) has cancelled an additional 368 flights in February, as the "no-fly" order on Boeing's 787 Dreamliner continues.
ANA has now cancelled over 1,200 flights since safety regulators grounded the entire fleet of Dreamliners on 16 January following concerns over the plane's battery.
More than 100,000 of ANA's passengers have been hit by the cancellations.
January's disruption alone has lost the company 1.4bn yen (£9.5m) in revenue.
The 50-strong fleet of Dreamliners, of which ANA has 17, was grounded after a battery on a Japan Airlines 787 caught fire, and a malfunction forced an ANA flight to make an emergency landing.
But investigations into the battery have so far proved inconclusive.

Boeing 787 Gets FAA Approval for Ferry Flight Today
By Susanna Ray & Mary Schlangenstein - Feb 7, 2013 2:36 AM GMT+0100.
Boeing Co.’s grounded 787 Dreamliner will fly today for the first time in three weeks after U.S. officials approved a one-time permit to ferry a plane to Washington state from Texas.
The trip isn’t a commercial flight, and the only people aboard will be those needed for operation, the Federal Aviation Administration said in a statement. The plane must fly directly to Boeing’s widebody-jet plant in Everett, just north of Seattle, from Fort Worth, where it was being painted for China Southern Airlines.
Investigators are still “weeks away” from determining what caused battery failures on the 787, the head of the U.S. National Transportation Safety Board said yesterday. The jets have been grounded since Jan. 16 after a fire on one and an emergency landing by another, and Transportation Secretary Ray LaHood declined to give a timetable yesterday for deciding on Boeing’s request to resume test flights.
“There is an increasing concern that this could take longer than earlier anticipated,” said Michel Merluzeau, a consultant with G2 Solutions in Kirkland, Washington.
“Boeing’s proposed solution to build a containment around the battery should certainly help, and adds an extra layer of safety in the unlikely event of another battery malfunction,” he said. “It however is only part of the solution which should include permanently resolving the root cause of the problems experienced by the 787 electrical system.”
For today’s ferry flight, the crew will have to perform “a number of inspections to verify that the batteries and cables show no signs of damage,” the FAA said. They will also be required to check for specific status messages that could indicate problems, both before and during the flight, and will have to land immediately if one occurs, the agency said.
‘Top Priority’
“While our work to determine the cause of the recent battery incidents continues in coordination with appropriate regulatory authorities and investigation agencies, we are confident - as is the FAA - that the 787 is safe to operate for this activity,” said Marc Birtel, a spokesman at Boeing’s commercial headquarters in Seattle. “Safety of the crew on board is our top priority.”
The grounding order won’t be lifted until the plane is proven to be safe, the FAA has said. Boeing has said it has hundreds of engineers working around the clock to resolve the issue as quickly as possible.
All Nippon
Japan’s All Nippon Airways Co. -- the first customer for the Dreamliner and the largest operator of the plane so far -- said today it canceled all domestic and international flights scheduled to use the new model through March 30. That means 1,887 flights are being canceled between the Jan. 16 grounding and March 30, affecting more than 126,000 thousand passengers, the Tokyo-based carrier said.
Investigators are looking at each of the cells used in the 787’s lithium-ion battery, the three windings in each of the cells and the component parts, NTSB Chairman Deborah Hersman said yesterday. That includes tests on examples of the batteries used in the jet.
The safety board is looking at “the macro level to the microscopic level on this battery,” Hersman said. The board has evidence of short circuits in cells of the battery, “thermal runaway” and an uncontrolled chain reaction, she said.
“Those features are not what we would have expected to see in a brand-new battery on a brand-new airplane,” Hersman said. “We want to make sure the design is robust and the oversight of the manufacturing process is adequate.”
Boeing said last week it’s continuing to produce 787s at a rate of five a month, ramping up to 10 a month by year-end, and is still working on the development of two bigger versions of the jet.
The plane is the world’s first composite-plastic airliner and the first to use new electrical systems to help save on fuel. It was three and a half years behind when it entered service with ANA in late 2011, after Boeing struggled with the new materials and manufacturing processes. The company has delivered 50 of the planes so far to eight airlines around the world and has orders for another 800.

Tesla CEO extends help to Boeing on battery issue
By Deepa Seetharaman
Jan 28 (Reuters) - Elon Musk has long considered Tesla Motors Inc the bold, nimble answer to the auto industry's cautious culture. Now the electric car maker's top executive has extended his help to another industrial giant: Boeing Co.
In a Jan. 26 message on Twitter, Musk said he was in talks with the chief engineer of Boeing's 787 Dreamliner plane, which regulators have grounded indefinitely after a string of malfunctions ranging from fuel leaks to battery meltdowns.
"Desire to help Boeing is real & am corresponding w 787 chief engineer," Musk wrote on the social media website.
Musk, who is also the CEO of space transport company SpaceX, told Reuters in an email late on Monday that SpaceX battery packs could be helpful for Boeing.
"We fly high capacity lithium ion battery packs in our rockets and spacecraft, which are subject to much higher loads than commercial aircraft and have to function all the way from sea level air pressure to vacuum. We have never had a fire in any production battery pack at either Tesla or SpaceX," Musk said in the email.
Boeing declined to comment or confirm if such discussions were taking place.
Boeing's chief 787 engineer, Mike Sinnett, has recently made presentations about the plane and its battery technology to reporters and industry leaders.
Musk's post came a week after his first dispatch to Boeing on Jan. 18: "Maybe already under control, but Tesla & SpaceX are happy to help with the 787 lithium ion batteries."
U.S. and Japanese authorities are investigating a fire and a smoke incident with lithium-ion batteries on two separate Dreamliners in recent weeks. The 50 Dreamliners in service cannot be flown until the U.S. Federal Aviation Administration is satisfied that the problem with the batteries has been fixed. The U.S. National Transportation Safety Board is still investigating what caused the first battery to catch fire.
Lithium-ion batteries are widely used in phones and hybrid cars because they are lighter and more powerful than traditional batteries. But if managed improperly, lithium-ion batteries can explode or catch fire, and some pose a greater risk than others depending on their chemical make-up.
The 787 is the first passenger jet to use lithium-ion batteries for back-up and auxiliary power. Tesla began using lithium-ion batteries in its Roadster, a two-door sports car that Tesla said could go from 0 to 60 miles (100 km) per hour in about 4 seconds.
In its Dreamliner, Boeing adopted a lithium cobalt oxide chemistry similar to that used in the Roadster, which Tesla produced from 2008 until last year.
Musk, a serial entrepreneur who gained fame after selling his Internet payment company PayPal to eBay Inc in 2002, has been quick to criticize the cultures of major car makers like General Motors Co and Ford Motor Co.
In a magazine interview with Esquire late last year, Musk was similarly critical of Boeing. He was quoted as saying, "You know the joke about Boeing: It puts the zero in being."
Musk later took pains to dismiss the story, written by reporter Tom Junod. "Junod's Esquire article had high fiction content," Musk wrote his Jan. 26 tweet.
Junod said Musk's dig at Boeing was on tape and his story was "more extensively reported than any story on Elon that preceded it."

787 grounded, but batteries can fly

STORY HIGHLIGHTS
Dreamliners grounded early Jan. because of battery fires
Now lithium ion batteries can be carried in cargo hold
Aircraft batteries with max weight of 77 pounds can be shipped; Dreamliner's battery is 63 pounds
WASHINGTON (AP) — At the same time the U.S. government certified Boeing's 787 Dreamliners as safe, federal rules barred the type of batteries used to power the airliner's electrical systems from being carried as cargo on passenger planes because of the fire risk.
Now the situation is reversed.
Dreamliners worldwide were grounded nearly three weeks ago after lithium ion batteries that are part of the planes led to a fire in one plane and smoke in a second. But new rules exempt aircraft batteries from the ban on large lithium ion batteries as cargo on flights by passenger planes.
In effect, that means the Dreamliner's batteries are now allowed to fly only if they're not attached to a Dreamliner.
The regulations were published on Jan. 7, the same day as a battery fire in a Japan Airlines 787 parked at Boston's Logan International Airport that took firefighters nearly 40 minutes to put out. The timing of the two events appears coincidental.
Pilots and safety advocates say the situation does not make sense. If the 787's battery system is too risky to allow the planes to fly, then it's too risky to ship the same batteries as cargo on airliners, they said.
"These incidents have raised the whole issue of lithium batteries and their use in aviation," said Jim Hall, a former National Transportation Safety Board chairman. "Any transport of lithium batteries on commercial aircraft for any purpose should be suspended until (an) NTSB investigation is complete and we know more about this entire issue."
Chesley "Sully" Sullenberger, a former US Airways pilot famed for his precision flying that enabled passengers and crew to survive an emergency landing on the Hudson River in New York, said in an interview that he wouldn't be comfortable flying an airliner that carried lithium ion aircraft batteries in its cargo hold.
"The potential for self-ignition, for uncontained fires, is huge," he said. The new regulations "need to be looked at very hard in the cold light of day, particularly with what has happened with the 787 batteries."
The battery rules were changed in order to conform U.S. shipping requirements with international standards as required by Congress, the federal Pipeline and Hazardous Materials Safety Administration said in a statement.
The International Civil Aviation Organization, a U.N. agency that sets global aviation standards, adopted the aircraft battery cargo exemption in October 2011, and it went into effect Jan. 1. The organization's standards normally aren't binding. But a provision inserted into U.S. law at the behest of the battery industry and their shippers says the rules can't be stricter than the U.N. agency's standards.
Previously, U.S. regulations prohibited the shipment of lithium ion batteries on passenger planes in packages weighing more than 11 pounds (five kilograms), although heavier batteries could be shipped on cargo planes.
The new rules allow the shipment of lithium ion batteries weighing as much as 77 pounds, but only if they are aircraft batteries. Shipments of other lithium ion batteries greater than 11 pounds are still prohibited. The 787's two batteries weigh 63 pounds (29 kilograms) each. It's the first airliner to make extensive use of lithium ion batteries, which weigh less and store more power than other batteries of a similar size.
The aircraft battery exemption was created for the convenience of the airline industry, which wants to be able to quickly ship replacement batteries to planes whose batteries are depleted or have failed. Sometimes it's faster to do that using a passenger plane.
The NTSB is investigating the cause of the 787 battery fire in Boston. Japanese authorities are investigating a battery failure that led to an emergency landing by an All Nippon Airways 787 on Jan. 16. All Dreamliners, which are operated by eight airlines in seven countries, have since been grounded.
The International Air Transport Association, which represents U.S. airlines and other carriers that fly internationally, asked for the aircraft battery exemption at the October 2011 meeting of the U.N. agency's dangerous goods committee.
The association argued that the exemption would give airlines "significant operational flexibility in being able to move aircraft batteries on a passenger aircraft where cargo aircraft may not be available over the route, or within the time required if a battery is required at short notice," according to a copy of the request obtained by The Associated Press.
Since the batteries have to meet special safety standards in order to be installed on planes, "it is believed that exceeding the (11-pound) limit for passenger aircraft will not compromise safety," the request said.
Some members of the committee opposed allowing shipments of lithium ion aircraft batteries on passenger planes, saying safety regulations that let the batteries be used onboard planes don't necessarily ensure they can be transported safely as cargo, according to a summary of the meeting posted online by the U.N. agency.
"One member had discussed this proposal with an engineer in their (country's) airworthiness office who was familiar with standards for batteries installed in aircraft," the summary said. "This colleague did not believe testing standards for installed aircraft batteries warranted special treatment for transport purposes." It was pointed out that the safety standards applied to batteries used in the operation of an aircraft are "narrowly tailored to performance issues and how the battery interacted with aircraft systems," the summary said.
The summary doesn't identify the committee member, but a source familiar with the deliberations said it was the U.S. representative, Janet McLaughlin. She abstained from the vote on the standards, said a federal official with knowledge of the meeting. Neither source was authorized to comment publicly and both spoke only on condition of anonymity.
The Japan Airlines fire ignited about half an hour after the plane had landed in Boston and nearly 200 passengers and crew members had disembarked. Firefighters were alerted after a cleaning crew working in the plane smelled smoke. It took nearly 40 minutes to put out the blaze.
The "multiple systems" that were designed to prevent the 787's batteries from catching fire "did not work as intended," Deborah Hersman, the current NTSB chairman, told reporters recently. The "expectation in aviation is never to experience a fire on an aircraft," she said.
Concern about transport of lithium ion aircraft batteries on passenger planes isn't limited to the batteries used in the 787. The Airbus A350, expected to be ready next year, will also make extensive use of lithium ion batteries.
Aircraft manufacturers are also considering retrofitting some planes to replace their batteries with lithium ion batteries to save weight, according to the airline association. The less a plane weighs, the less fuel it burns. Fuel is the biggest operating expense of most airlines.
Cargo airline pilots long have complained about the dangers of transporting lithium batteries. The batteries are suspected of causing or contributing to the severity of an onboard fire that led to the September 2010 crash of a United Parcel Service plane near Dubai, killing both pilots. The two pilots of another UPS plane barely managed to escape the aircraft before it was consumed by fire moments after landing in Philadelphia in 2006.
Lithium-ion batteries can short circuit and ignite if they are improperly packaged, damaged or have manufacturing defects. Fires involving rechargeable lithium-ion batteries can reach 1,100 degrees Fahrenheit (593 degrees Celsius) , close to the melting point of aluminum, a key material in the construction of most airliners.

A questo punto, semplificando brutalmente, il problema dovrebbe essere circoscritto a batteria, caricabatteria (chiamiamolo così) e circuiti di controllo. Ma non è che la certificazione, tra Yuasa e Boeing, sia stata un po' "sportiva"?

A questo punto, semplificando brutalmente, il problema dovrebbe essere circoscritto a batteria, caricabatteria (chiamiamolo così) e circuiti di controllo. Ma non è che la certificazione, tra Yuasa e Boeing, sia stata un po' "sportiva"?

Ottimo!
Ora all'appello mancano solo i placet di Sandro Giacobbo (non appena avrà finito di disquisire coi quadri) e del maestro di vita mario pacheco do nasimiento; poi il tuo studio potrà essere pubblicato su Nature.

.................. Cavolo............... il danno di immagine x il 787 peggiora sempre di piu'................ se non tornano a volare in fretta........ prevedo grosse catastrofi....

Mi sembra però una dichiarazione un pò azzardata. Ad oggi il problema non è stato risolto, è vero, ma se poi domani viene trovato il rimedio cosa fa LOT? Lascia ugualmente a terra i suoi 787?
A me sembra solo una prima dichiarazione volta ad aprire la strada a richieste di compensazioni economiche a Boeing.

Sembra che le rogne alle batterie agli ioni di litio del Dreamliner, abbiano convinto Airbus a rinunciare a questo tipo di accumulatori sul 350.
Airbus will not use lithium batteries in A350: source
AFP | Fri, Feb 15 2013
PARIS - Airbus will not use lithium batteries in the A350 long-range liner under development, a company source told AFP on Friday, as investigations continue into battery fires that have grounded rival Boeing's 787 carriers.
"The first planes will be delivered with cadmium, not lithium batteries," the source said, adding that the airliner's first test flights will nevertheless take place with the lithium batteries.
The announcement comes as Boeing's 50 Dreamliners in service around the world have been grounded since January, after battery smoke forced an emergency landing of one plane and a battery fire was reported on a parked plane.
US air safety investigators have since zeroed in on how a battery fire occurred on the parked plane - a Japanese Airlines 787 at Boston's Logan airport - saying that evidence pointed to a single cell on the eight-cell lithium-ion battery, which short circuited, leading to a rise in temperature.
Investigators do not yet know what specifically caused the short circuit.
The Airbus A350 is due to enter service in the second half of 2014, with the company hoping the liner will make it competitive in the long-haul market, where its planes have found it hard to challenge Boeing's 747s and 777s.
