787 Certificated!
There was a very long thread recently on Airliners.net about the financial troubles QANTAS is in. I had no idea they were under such commercial pressure, but it is apparently an acknowledged fact.
A lot of interior decisions are the responsibility of the airline, not the manufacturer. I’m thinking of the seats, and how they are arranged.
With regard to what Boeing provides, I seem to remember that the lighting was different, the overhead bins larger, and the windows were much larger, on the 787.
And then there is what cannot be seen, but only felt: The higher pressurization/lower cabin altitude, and the humidity control.
Finally, I’m sure the In Flight Entertainment (once again provided by a subcontractor) is several generations ahead of that in the 767, given the rate of improvement in electronics.
More infighting
IMHO, due to this accident, there has been a subtle simmering of tension between Airbus and Air France for quite some time. Now, the Pilots union is also entering the fray.

Oh my gosh, Jay, could you PLEASE stop quoting Sully as if he were Moses descending from the mountain with the commandments? I may have to start quoting Kohei Asoh all the time!
Amiga, I would enjoy hearing the specifics of the two areas you mention.
I’ve always thought that Airbus tepid support of Extended Twin Engine Operations was due to wanting to protect their investment in the 340 and 380, and also due to some of their prime customers not exactly embracing it either. Lufthansa comes to mind.
agincourt, i don’t have much knowledge of the rules for freighters. i would suggest going to a search engine and typing “far 121.161” and then start looking at the regulations after that one. Of course, these are U.S. regs, carriers from other countries wouldn’t necessarily need to observe them, but as a U.S. producer Boeing is building their aircraft to comply with U.S. regs.
I seem to remember that all the early engines burped a small amount of fuel when they shut down. As a mechanic, if you were doing engine runs/trimming, you didn’t want to be under the drain mast when the engine shut down or you would get a few ounces of fuel on you. The last 20-30 years or so, the engine manufacturers have developed a system to catch that fuel, or modified the engine so it doesn’t do that little squirt.
With regard to ETOPS for the 747, yes ETOPS applies. The FAA changed the regulations in 2008. One of the changes what the definition of ETOPS from Extended Twin Engine Operations to Extended Operations. The intent was to standardize the regs. Prior to the new regs you had scenarios where, for example, a 4 engine airplane might be 3 hours from an airport but only had 2 hours of fire suppression in the bag bins because 4 engine airplanes were “safer.” The industry finally realized that if you are on fire or out of fuel, it doesn’t matter how many engines you have. A lot of other regs that came into being at the same time “legitimized” Extended Twin Engine Operations, which until that time had operated under an Advisory Circular. Boeing supported the new regs, Airbus was not obstructive, but their level of support was certainly tepid.
There was a post on airliners that indicated only the drain mast on the engine was damaged. A fairly quick replacement and good to go.
More details about delivery schedule. Apparently both the 737 and A320 deliveries are to commence in 2013, with 737RE’s beginning in 2018 and A320NEO beginning in 2017.
Its interesting to me that AA have no only ordered both the 320 series and the 737 series, but have ordered the legacy and updated models of each. Kind of plays havoc with fleet standardization.
I still wonder about the ability of the manufacturers (especially Airbus since they have so many recent orders) to meet the delivery schedule. Granted, its a good problem to have and we don’t know the details of the contracts.

I believe that it said the return flight arrived one hour late, it did not say the NRT departure was only delayed one hour.
In other words, who knows how much ground time was originally scheduled in NRT?
For example, if it had a long layover, say 8 hours, and the ground crew required 9 hours to perform the required inspections and maintenance, that would provide for an hour delay upon arrival back at home base and still given the ground crew in NRT 9 hours.
Ok, lets spin the numbers your way.
The entire GE90 series has those 71 shutdowns in roughly 24 million flight hours. The Trent’s 88 IFSD were accumulated in only 18 million flight hours. The Trent is a lot less reliable than the GE90 series.
And in the last 12 months Trent has had 3 IFSD whereas GE90 has had 2…..even though GE90 has 4.6 million FH compared to only 1.8 million FH for the Trent. GE90 flew 2.5 times as much over the last year and had fewer total shutdowns and the -115 had none!
Composites are here to stay.
Remember, this is only the first generation, they will continue to get better.
Composites neither fatigue nor corrode.
I’m more concerned about all the new systems on the 787…..we’ll see how they work out. IMO Airbus has taken a much more rational approach in keeping traditional systems on their first composite airplane. Having said that, further A350 delays are unavoidable IMHO.
Ha! Good one, it IS a little damp but the computer monitor keeps me warm.
As for you, I imagine its pretty windy and cold up there atop Mount Olympus…
