Of course the 747 has evolved over the years, the 747-400 is a very different beast to the 747-100 of 1970. However that does not change the fact that the basic airframe was designed in the 1960's and the structural architecture is largely unchanged. To have done otherwise would have been cripplingly expensive and unnecessary (the 747-400 is more than a decade old - dating from long before Airbus were interested in the Jumbo market). For it to have undergone the changes you seem to be suggesting it would have been just as easy for Boeing to design an all new plane of their own.

Also the aircraft was designed the old fashioned way with draughtsmen and drawing boards. I'm saying not there's anything wrong with this but aircraft design has come a long way in the last 30 odd years and modern CAD procedures mean that the design of the A380 (as with the 787 or any other new type) is as efficient as current knowledge can possibly make it.

Applying CAD techniques to 747 upgrades is basically tinkering with and refining the existing form. Naturally this will yield less spectacular results than designing a completely new aircraft from scratch, (for a parallel it is like the difference between designing the F/A-22 or simply upgrading the F-15, think about that - the 747 is older than the F-15 but the A380 is newer than the F/A-22 - see how far design technology has progressed?)

If Airbus didn't believe they could improve upon the 747 by a significant margin do you really think they would have even bothered trying to shake the 747's iron grip on the market? Clearly Boeing thought they couldn't as they were content to sit back and say the current 747 would be good enough for the foreseeable future, a position which the rather hurried 747A proposal now shows to have been wrong.

Just how the economics of the 747A truly stack up against those of the A380 is something we will only truly know when both aircraft are competing in service, what 2010? by which time the A380 will have already been in service for four years.

You also raised a point about the engines, what was it, the 747A will have better engines?

Airlines will specify whichever engines they want, thats the beauty of underslung pods, you can fit any suitable engine to any plane and if the engines of the 747A ARE significantly better than the A380's R-R Trents they will simply be retrofitted to wipe out that advantage.

edit; whats that about renaming the 747? I don't get what you're on about there at all I'm afraid.

Yes, we could simply say that the Boeing 747 was just perfect since the first rolled out to the runway. But the 747 division of the Boeing factory is the most advanced among all others, even if the 787 is being engineered with computer technology. And we shouldn't forget that a 747 has 4million parts from all around the World, and they aren't handmade at all.

But all this is simply manufacturing process, and a Boeing is leaving the factory every 8 days. That is a rather good quota, I guess.

So, how will Airbus make hundreds of planes while rolling around the A380 parts through avenues and streets of large cities? I really mean, how?! I've seen on TV , and I was really amazed, how it is done. Anything goes wrong in the shipping, anything, and the Airbus will loose huge money.

While Boeing has all the access to sea, railways, highways and the air. The Airbus factory is yet very far from this, and perhaps in the longterm future they will get somewhere.

So what will the investors say? "If you don't build me an A380 until the desired date, I am gonna buy a Boeing 747!", Well, that's about it. And I have a feeling that at the Boeing they know some stuff very well, because they are not stressed at all. They will make a 747 every six weeks (that's the manufacturing time right now), while Airbus will NOT be near this quota at all. Well, this is a very important issue, and concerns a lot of airplanes!

I'm not having this at all, you are simply ignoring what I say and making up your own points to answer.

Where did I say that it was handmade? Don't be silly.

No, it isn't. Its design. If modern design allows for a lighter structure then that allows for more fuel for greater range, likewise if the design is more aerodynamically efficient throught the use of computer aided design this has a knock on benefit for fuel efficiency and thus again benefits range. These are highly significant elements and not simply 'manufacturing process'

Does this sound familiar? "And we shouldn't forget that a 747 has 4million parts from all around the World," Do you know what contradiction is?

While Boeing has all the access to sea, railways, highways and the air. The Airbus factory is yet very far from this, and perhaps in the longterm future they will get somewhere.


What we have no roads, sky, sea or railways in Europe?

Instead of this rambling nonsense how about the real points I made in those two posts which have gone ignored? Maybe you don't have the answers?

- Anyone manufacturing large passenger jets today is operating an advanced process.

Wake up.

- Are you just trolling here?

Has it escaped your notice that Airbus has out-sold Boeing (IIRC since 2003).

That means hundreds of planes.

That means (given the multi-national way Airbus works) transportation by air, sea and road.

Self evidently the system works.

(and the methods used to move the first examples of the A380 about are not necessarily indicative of how the mass production systems will work)

So what will the investors say? "If you don't build me an A380 until the desired date, I am gonna buy a Boeing 747!", Well, that's about it.


- Sorry matey but this is just ludicrous wishfull thinking.

And I have a feeling that at the Boeing they know some stuff very well, because they are not stressed at all.


- Don't be naive; Boeing dare not give the impression of how they truely feel as it would spook their shareholders and they are one group of people who have had quite enough 'agitation' from the Boeing board lately.

They will make a 747 every six weeks (that's the manufacturing time right now), while Airbus will NOT be near this quota at all. Well, this is a very important issue, and concerns a lot of airplanes!


- The 747 is an old plane on the wind-down. Airbus' A380 has only just started (and is already half way to break even having already sold approx 150 examples before it's wheels have even left the ground)

They can warm over the old 747 design all they like but it is old and it has had it's time.
It'll be about for some time yet but, let's put it like this, there are a hell of a lot more sales behind it than it has to look forward to, right?

Wow I cant believe this thread, no one is telling any truth or facts yet in this conversation. Like the 787 being 100% composite....whew.. wont happen today.
and the A380, glued together airbus, just another 10 year aircraft in the sky. And yes boeing already has parts being produced for the 787, planned to go into full production in the next couple of years. When you work as a structure tech. on heavy commercial aircraft for almost your whole life then you know what you want to fly on or not. And airbus is on the bottom of my list. Just go to any aircraft maintenance facility that works on Boeing, Airbus, and even Douglas and ask which plane do you think is built the best? Douglas is known to be built like a tank, lasting forever, Boeing cutting edge technology in airframe, and airbus glued together cant understand their blueprints and not mechanic friendly at all.
What would you fly on? See there is more than meets the eye here, airplanes fly for a long time and to do this they need to be maintained, if it is hard to do this when people start getting frustrated and dont do there job a 100% which is needed in aviation. Boeing, every time they make a new airplane they try to make it easier for the mech to get his job done, Has not been the case for airbus. The first time I see that A380 role onto the tarmac for maintanence I will be shaking my head because it is going to be a nightmare.

And boeings planes might look similiar but under ther skin they are very different. Just look at the 777, composite floorbeams, and fly by wire the first for boeing. trust me as a mech composite floor beams are a big thing, corrosion loves aluminum and the less the better. But see a aircraft cannot be 100% composite, since technology does not allow this yet. Landing gear, wingroots, spars, and the skin made out of composite. This is a dissaster waiting to happen. The main structure has to be able to hold a load and take the pounding of landing.... well i better stop bacause i could write for ever.
