Bingo ! Good News pour le B787 ! Lien : http://www.flightglobal.com/articles/20 ... -time.html DATE:11/06/08. SOURCE:Flightglobal.com FlightBlogger: Boeing powers-on 787 for first time By Jon Ostrower Power-on testing for the first 787 flight test aircraft has commenced at the final assembly centre in Everett, Washington, FlightGlobal.com affiliate FlightBlogger reports. Boeing has confirmed the 787’s electric systems has been powered on for the first time within the aircraft, almost three weeks ahead of an internal deadline. Bravo, Pat SHANAHAN ! Maintenant, reprenez dupont, et son clavier ! Nous garderons la robe de chambre ! ------------------- “We’re pleased the process has begun, and we are confident we’ll meet the milestone in June,” Boeing told FlightBlogger. Power-on testing of all the 787's systems is expected to take several weeks in advance of a first flight event expected in the fourth quarter. First delivery of the 787 to launch customer All Nippon Airways has slipped at least 15 months to the third quarter of 2009. ----------- Voilà ! Boeing doit être soulagé ! |

Bonjour Des batteries lithium améliorées pour le 787 !! Pour bientôt ... cela va dans le sens des recommandations de la FAA !! ------------ L'article ----------------- http://www.flightglobal.com/articles/20 ... rvice.html Boeing looks to boost 787 lithium ion battery service life By Jon Ostrower As Boeing activated the electrical system of its 787 for the first time last week, the airframer acknowledged that it was exploring a change to its power system for production aircraft due to longevity concerns. Boeing will move away from its original lithium ion battery design for its main and auxiliary power units, flight-control electronics, emergency lighting system and recorder independent power supply. Instead, Boeing is investigating the incorporation of manganese inside the lithium ion battery to boost service life. Boeing has not determined which 787 will be the first to receive the new battery modifications, although multiple programme sources have told Flight's FlightBlogger affiliate that the new battery could be introduced as early as Airplane Seven, the first production 787 scheduled for delivery to All Nippon Airways in the third quarter of 2009. The sources add that the first six flight-test 787 aircraft will have the original feature lithium ion batteries, but will be retrofitted with new batteries before delivery to airline customers. The use of lithium ion batteries is to be the first application of the technology on a commercial jetliner. The US Federal Aviation Administration voiced its concerns about the use of lithium ion batteries in an April 2007 proposed special condition. At the time, the FAA said that the 787-8 would have "novel or unusual design features" and required, "additional safety standards that the [FAA] administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards". The FAA cited three specific safety concerns about lithium ion batteries, which included overcharging, over-discharging and the potential flammability of cell components. Boeing underscores that the change in battery technology is unrelated to any safety concerns and the airframer is fully complying with the 2007 Special Condition. Japan's GS Yuasa supplies the batteries for the 787 Dreamliner. JPRS Paris _________________ JPRS |

http://biz.yahoo.com/prnews/080620/aqf017.html?.v=50 Friday June 20, ADVERTISEMENT Power On is a complex series of tasks and tests that bring electrical power onto the airplane and begin to exercise the use of the electrical systems. The 787 is a more-electric airplane with the pneumatic, or bleed air, system being totally replaced by electronics. "The team has made great progress in bringing the bold innovation of the 787 to reality," said Pat Shanahan, vice president and general manager of the 787 program. "There is plenty of work to be done between now and first flight, but with every step forward we grow more and more confident." The Power On sequence began in early June with a series of pretest continuity checks to verify that the wiring installed in the airplane had been connected properly. Upon completion of those checks, the Boeing team plugged in an external power cart and slowly began to bring full power into each segment of the system, beginning with the flight deck displays. From that point forward, the pilot's controls were used to direct the addition of new systems to the power grid. At each step of the testing, power is allowed to flow into one additional area and gauges are used to verify that the right level of electrical power reached the intended area. "We are very methodical in ensuring the integrity of the airplane's systems," said Shanahan. "In completing the Power On sequence, we have verified both that the electrical power distribution system is installed as designed and that it functions as intended." An inside look at the Power On testing sequence will be featured on http://www.boeing.com and newairplane.com beginning Monday at 5 a.m. PDT. Work will continue to finish building the first 787 and further test its readiness for operations. First flight is expected in the fourth quarter. The Boeing 787 Dreamliner is a more fuel-efficient mid-sized jetliner capable of serving on long-distance routes. The 787 is expected to enter revenue service in 2009 after an extensive flight test program. |

Bonsoir .. Power on ! Bravo !! Bon, c'est bien !! Ils ont allumé la lumière ... et ça marche ... pas eu besoin des pompiers ! Les composants sont au bout des fils et circuits !! Cela ne signifie pas qu'il va voler demain matin ... Un grand pas ... mais les moteurs ne sont pas en place, ils étaient simulés, merci Sunstrand-Hamilton ... la repose moteurs, c'est pour next month .... et re-power on quand l'avion sortira du hangar, grandeur nature, cette fois ! le 1° vol ne sera plus éloigné Et il reste à contrôler comment fonctionne et inter-acte tout ce beau monde électrique, pressurisation, hydraulique, freins etc !! 2-3 mois pour vérifier et ... corriger ... Rien d'extraordinaire sur un avion normal ! Mais peut être aussi les effets positifs d'un an de retard à ce stade, et une meilleure préparation ! Mais c'est quand même pointu l'électricité sur le 787 ! Surtout avec la FAA qui rode autour !! Faut espérer qu'ils ne vont plus rien inventer !! On suit les progrés ...

http://biz.yahoo.com/prnews/080621/aqsa001.html?.v=29 787 Dreamliner Fatigue Airframe Departs Factory Saturday June 21, 12:45 am ET EVERETT, Wash., June 21 /PRNewswire-FirstCall/ -- Boeing (NYSE: BA - News) yesterday moved the 787 Dreamliner designated for fatigue testing from the final assembly factory in Everett, Wash., to another production bay at the facility, where assembly work will continue. The move paves the way for the second flight-test airplane to advance to the next position in the production line today. The first Dreamliner remains in the nose-to-door position and the third flight-test airplane is in the first position. It will remain there until the fourth flight-test airplane is ready for assembly to begin later this month. |

Bonjour, chers tous ! Article intéressant ! On avait dit, après analyse raisonnable des données disponibles pour tous, y compris le grand public, dont nous faisons partie , que : -- malgré les bruits lénifiants émanant de Boeing et du quartier des BCL,.... -- la moyenne des retards, dans les livraisons des B787, pourrait être plus proche de 27 à 30 mois ! Ah, ... la pertinence de l'analyse (pas d'avis infondé ! ) s'avère utile ! -------------- Lien: http://www.flightglobal.com/articles/20 ... -787s.html DATE:20/06/08. SOURCE:Flight International Monarch faces 30-month delay on 787s By Kieran Daly 30 mois ! UK charter and scheduled carrier Monarch Airlines has emerged as one of the airlines facing the longest delays in delivery of its ordered Boeing 787's. The London Luton-based operator has six Rolls-Royce-powered 787-8s on order for delivery from late 2010 with four options., primarily as an Airbus A300-600 replacement. But ....... Monarch managing director Tim Jeans said: "We are in the worst part of the 787 delays. We are being told spring 2013 at best. The 787 was supposed to relieve the situation with the A300, which are not as reliable as we would like. "Just about everything has gone on to the back-burner. We have stood down the project team - just keeping a watching brief. And we won't revisit the financing for 12-18 months." Monarch is also looking for four to six Airbus A330s or Boeing 767s for the immediate future and is now exploring the possibilities for addressing that requirement and filling the gap left by the 787 delay. Jeans says: "A330s are like hens' teeth unless there are failures. There is no glut. The options are pretty limited. There is very little cascade of 767s and A330s from airlines. So for airlines like Monarch that will take a mix of new-build and used aircraft. It is not easy." He says Monarch will look to make a decision about filling the 787 gap in the last quarter of this year, and is sceptical about whether Boeing's moves to increase 767 output could be a solution. "It's interesting but I think we will be well down the list of Boeing's priorities for people to get those," he says. He is also interested in the possibility of securing new-build A330s as an interim solution if Airbus increases output. Si Monarch trouvait une "solution A330", il pourrait 'annuler' ses cdes. B787, pour aller vers l'A350-XWB ! (Message édité par sevrien le 21/06/2008 12h02) |

La solution est peu etre trouvé avec le report de la commande US des ravitailleurs. |

| Si Monarch survit la crise en 2011 (la date prévue de la 1ère livraison, peut être le retard devient un problème. Or, dans l'état actuel sa survie n'est même pas garantie. | ||

Je ne suis pas sûr. Il me semblait que la manière dont les choses devaient être vue était : - commande ravitalleurs => 2nde ligne d'assemblage 330 aux US => 330F assemblé hors Toulouse => de la capacité de production 330 libérée à Toulouse. - pas de commande ravitailleurs => on continue comme actuellement. Me trompe-je ? |

Dupont trouve des excuses à boeing pas nouveau. Mais effectivement il risque de perdre beaucoup de commande de 787 dupont vu les compagnie qui les ont achetés. Air berlin va devoir repoussser les 787, ba etudie d'autre possibilité, ANA idem, les americains sont tous pratiquement dans le rouge et vont devoir repousser leurs commandes ou bien les annuler.....  |

| Une analyse justificative de ce commentaire, svp ! Si Monarch s'est bien débrouillé dans son contrat avec Boeing, il se pourrait que les compensations exigibles soient fondées sur une notion de "specific performance" (sous "Equity Law"), et que Boeing ait a garantir la capacité de survie de Monarch ! Vous n'en savez rien ! | ||
