Bonsoir !
Vu par Jeannot chez les collégues (quote, seulement quand on peut vérifier même après ... pas tjrs aisé ) !
Boeing sort la grosse Bertha pas sûr qu'elle porte de Chicago à Seattle, menfin !
10 787 alignés sur le tarmac pour les essais, Banzaï, faut que ça s'agite, c'est la guerre aux délais qui vient d'être déclarée !
Le Boss a du taper sur la table, à mon avis il est au bout du rouleau !
Sur le blog de Scott Hamilton !
Ce n'est pas une blague , lire la suite, et gare aux collisions sur les pistes !
2 Questions :
1/ Sont ils tellement en retard, pour sortir les Panzers ... sûrement, le 2Q à la vista !
2/ C'est gentil mais avec quels moteurs ... Noté que les avions assemblés le sont sans moteurs !
Kanban et just in time, des explications qui ne me suffisent pas ... à moi du moins !
On peut juste espérer que RR et GE suivent la charge des cuirassés !
Les Etops reviennent aussi sur le tapis, au passage !

Boeing to use 10 787s for tests Boeing will use 10 787s to complete
certification, a Wall Street aerospace analyst reported today in a
research note, the first time this has been revealed.
Richard Safran of Buckingham Research writes:
Originally,
BA intended to use six 787 test aircraft for certification. BA CEO
Jim McNerney previously spoke about contingency plans to maintain the
787 flight test schedule. One plan was to shift ETOPS (Extended
Twin-engine Over-ocean Performance Specification) testing from the
original 6 flight test aircraft to 787 #7-10. In order to prevent
further delays to the 787 schedule, BA is now using 10 aircraft in the
certification process. The engine failure of 787 #9 in ground test
delayed certification (and first delivery) because RR did not have a
replacement. Since BA is now relying on 10 aircraft for certification
and given the difficulty getting 787 #6 into the test program (now
slated for September), we think it’s possible first delivery of the
787 could slip beyond 1Q11 to 2Q11.Separately. we inquired of Boeing about some other aspects of the
engine issue (Rolls-Royce, as is typical, did not respond for comment).
We asked Boeing why, after 2 1/2 years
of delays, there were more engines available that could be used to put
on the All Nippon Airways plane to maintain first delivery in January
(December already having been largely written off by
analysts)–especially considering that Boeing planned to have 30
airplanes ready for delivery by the time certification was achieved.
Boeing responded that engines are delivered “just in time,” a common
supply chain method to control inventory costs.
Indeed, of the 12 787s assembled but parked on the ramp at Everett
(WA)’s Paine Field, where the 787 is assembled, none has engines.
Why was the engine that had the uncontained failure at Rolls so critical to the program and ANA’s delivery?
Boeing said that two engines are required for ETOPS and “function and
reliability” (F&R) testing and are uniquely instrumented.
“Some of this testing will occur on airplanes later in the production
sequence vs the primary flight test airplanes,” Boeing told us. “This
is not out of the norm for new airplane programs.”
Unaware of the plan to use 10 airplanes when we asked our questions,
we do not have information about the tasks planned for the extra four
aircraft.
