Boeing Dreamliner receives U.S. approval for expanded long-range flying

The FAA clears Boeing's (BA) 787 Dreamliner to operate on a wider range of routes, enabling the jet to handle longer oceanic and polar crossings as much as five-and-a-half hours from a suitable landing field in the event of an emergency vs. the three-hour limit since its 2011 launch.

The performance extension is especially important for airlines based in the Southern Hemisphere that fly long routes over water; Air New Zealand is set to take delivery of the first of the larger Dreamliner model in the middle of the year.

The FAA approval formally applies only to U.S. carriers, and within that group only United Airlines (UAL) now operates the 787, but regulators in other countries typically follow the FAA's lead.

    NTSB calls for improved battery testing, certification in wake of Boeing 787 issues


    Deborah Hersman, then-chairman of the National Transportation Safety Board, speaks during a news conference in Washington, D.C., in February 2013. The top U.S. transportation safety investigator questioned the adequacy of tests that prompted U.S. regulators to allow Boeing Co. to use lithium-ion batteries on the 787 Dreamliner, which was grounded in early 2013.
    The National Transportation Safety Boardon Thursday released a set of recommendations it has handed off to theFederal Aviation Administration that call for an improved process to test and certify lithium-ion battery systems on aircraft — a process it says was “inadequate” when those batteries were originally certified for use on the Boeing Co.’s 787 Dreamliner.
    The recommendations include developing better testing measures that would be required as part of the certification of future aircraft designs, the re-evaluation of the potential for short circuits on planes already in service, and the inclusion of an independent panel of experts in the certification process for all new technologies being installed on aircraft.
    The recommendations stem from the board’s investigation into the lithium-ion battery malfunction that sparked a fire in early 2013 on a 787 that was parked at Boston’s Logan Airport, an incident that was among those that led to the aircraft’s global grounding.
    The board is expected to complete its full report on that incident later this year.
    The NTSB’s full statement on its safety recommendations to the FAA can be foundon the board’s website.

    Boeing redesigns 787-8 battery but the batteries continues to have problems,


    July 2013 saw several 787 where still having problems in many systems


    Dreamliner a timeline of problems



    This design battery design does not have any coolant air for the battery or any type of sensors on the battery that could alert the flight crew of any type of problems


    The 787-8 aircraft electrical circuit breakers are not tripping that are design to prevent electrical system from overloading.


    The cost of the 787 battery is $1600.00 and the weighs is 68 pounds
    Placing lithium-ion batteries in a box is not a fix since there is NO Fire Extinguisher that can put out a Lithium-ion batteries fire on board an aircraft! See the crash of UPS flight 6 a 747-400F that was carrying ion battery


    What inside a Lithium-ion battery
    The cell's energy is equal to the voltage times the charge. Each gram of lithium represents Faraday's constant/6.941 or 13,901 coulombs. At 3 V, this gives 41.7 kJ per gram of lithium, or 11.6 kWh per kg. This is a bit more than the heat of combustion of gasoline, but does not consider the other materials that go into a lithium battery and that make lithium batteries many times heavier per unit of energy.



    Where is all the instrumentation on the batteries at ?


    and placing the batteries s inside a box is not a fix ?


    Boeing Faulted by Norwegian Air on 787 Short Circuit


    Boeing Co. (BA) engineers lacked the expertise needed to diagnose a fault on a 787 Dreamliner, causing them to short-circuit the marquee plane and leave its passengers stranded, operator Norwegian Air Shuttle (NAS) ASA said.



    The 787 was started on 2-28-2003 and the stock was selling at $20.00 and only 140 787-8 has been deliver to date and the program need to sell 1100 787 to break even but that was before all the problems

    Yes this was coin in an All Hand Meeting for 777-200 with Phil Condit in the earl 1990's
    (In 1986, he was named as executive vice president and general manager of BCAC, then executive VP and general manager of the 777 program division. Known as the 767-X in 1989)


    The other question that was ask to Phil that day if the FAA does not allow two engine aircraft to fly over water, would the 777-200 going to be a three or four engines aircraft which was the requirement before the 777-200
    Since then ETOPS has been upgrade to cover all two, three, four engine aircraft on the number of Live Rafts, Engine Fire Bottle and Cabin Fire Extinguisher, Oxygen Bottles ect that carry on board the aircraft flying over water


    But how long can a person tread water for ?
