Pooh,
Hmm, I looked for the article I read that number in, but can't find it. Will try to call Airbus later today to verify. But if you consider the amount of avionics and standard aviation equipment going in, it makes sense. I see trouble looming as the asian countries get the expertise and no longer require *us* ! Oh, I agree. Fully. -- Thomas Borchert (EDDH) |

... "Pooh Bear" wrote in message Fuel efficiency ( cost per seat-mile ) is what it's about. This factor is skewed by amortised cost of old but serviceable a/c - like the 727s I just mentioend. Not efficient - but the lease purchase was paid off decades back. I tell you what--you want to start up a new low-cost airline here in the states with 727's, be my guest---but don't be planning on getting many financial backers. Question - how efficient is a 727 re-engined with the RR Tay conversion? These seem popular with the higher end of biz-jet operators. I think someone on here, though may have been on TV, said that the difference between cruise speeds on various airliners is to do with the critical speed of the wing. Above this speed, the thrust required is much more, so you use much more fuel. The 747 was designed for a faster speed in this respect so has a higher cruise speed? I think the 727 was quoted as being quite good at M 0.75 but not at 0.85? Something like that? Paul |

If de Havilland hadn't been obliged to scale down the Trident to suit BEA and then later scale it back up again ( to suit BEA ! ) , it would have been far more sucessful. Indeed. You could say it was tremendously successful eventually, but by then it was known as the Boeing 727. Boeing apparently hired 9 of the Trident's designers and they made one without one hand tied behind their backs. Paul |

"David CL Francis" wrote in message ... Just dug out a Concorde brochure, written when they still optimistically hoped to sell many and fly them all around the world. Pacific routes are included as follows West Coast of USA; Anchorage, Seattle, San Francisco, Los Angeles, San Diego and Acapulco were all shown as legs to Honolulu. Onward links from Honolulu were to Tokyo and to Auckland and Sydney via a stop at Nandi. West Coast USA to Australia in 2 stops - that's all. If any more Concordes had been made, they would have been the "B" model. These would have had leading edge devices and other high lift tricks to lower take-off and lading speed. They also had more efficient engines. They apparently would have used 30% less fuel, giving the plane a longer range (I'm not sure I have this absolutely right, I'm quoting from my memory of reading Brian Trubshaw's autobiography). Regarding paying back of the design costs, it may well have happened if the airlines had taken up the 70+ options they initially specified. Of course, as has been mentioned, the venture as a whole continues to pay in the guise of Airbus. Paul |

... It looks like the competition is good for the airlines and the travelling public, but very risky business for manufacturers. Mmm. Competition. How much competition is there if Airbus make the only real choice in the 500+ seat market and Boeing make the only real choice in the 200-300 seat market? :-) Paul |

Paul,
and Boeing make the only real choice in the 200-300 seat market that's a big if, if ever I saw one. -- Thomas Borchert (EDDH) |

And what happened to the plans to use the 767 as replacement for the KC-135? Still in limbo for the USAF. Italy and Japan have purchased 767 tanker mods, though. Anithing tp do with teh fact that Italian Avionavali will make the transformation? Looks like a political choice. -- Fritz |

7E7 will offer airlines a new airframe (they can't fly the same old ones forever) No ? No. Aircraft have definite service lives. Some helicopters don't. -- Fritz |
