Not bad, quite impressive!!
Interesting to note about CX possibly going with the 747ADV to replace the A340-600's
"A380 fuel burn better than expected
Wednesday May 25, 2005
A380, which completed its ninth test flight over the weekend, has exceeded its fuel burn goals, Airbus sources told ATWOnline. While coy on confirming the results, a spokesperson told this website that the aircraft is having a near-perfect flight test program. During the flights, some of which have lasted 8 hr., the A380 has been flown to an altitude of 43,000 ft. and at speeds up to Mach 0.89. Airbus plans to unveil the second A380 sporting a Singapore Airlines livery "shortly." Despite the positive A380 news, Cathay Pacific is still leaning toward the 747ADV and 777-300ER for its fleet growth/replacement order, which is expected in July, sources at the airline said. The fleet replacement plans currently call for its three A340-600s, leased from ILFC, to be replaced by 747ADVs.

I never doubted about if the A380 will meet the promised fuel burn or not. In these days with modern construction aid such as CATIA or other software, it is much less risk to create new designs which would maybe not meet the requirements.
CX is maybe playing a bit with AIRBUS regarding the consideration of the 747ADV
to get a better price for the A380. Who knows?

Yes it's maybe to counter Boeing and to dissuade Boeing to building the 747Adv. It might be true, but Airbus announces that just when Boeing is on its last step of giving the GO AHEAD for the 747Adv.
Anyway, even if I think they have calculated all the parameters, I will believe the fuel burns of the airlines flying it. It's even not fitted with seats, galleys, bars... And a lot of surprises can arise from the interior.
But I hope the A380 will be a huge commercial and technical success.

Quoting BoogyJay (Reply 11): ... , but Airbus announces that just when Boeing is on its last step of giving the GO AHEAD for the 747Adv.
Boeing on it's last step for the 747Adv? Since when does Boeing plan the 747 Adv, since when is it the last step? Boeing always talking about the 747Adv - since ages, and nothing happens. So shall A wait as they waited for B's ok to the co-operation of the Super Jumbo?

It is not a secret anymore that Boeing is seriously working on the 747Adv. There were some interesting threads about this topic recently on this board so you might consider a search in case you´re interested.
The 7e7 was also discussed extensively before it was officialy launched and so was the A380, of course. I see nothing wrong with discussions concerning rumours about anticipated aircraft launches and their possible influence on decisions of the respective competitor.
I meant that Boeing is PROBABLY (sorry I forgot this word) on their last step considering that if they announce the B747Adv, it may well be in Paris mid-June.
So as the deadline of the Paris Air show is coming quickly, and with that the possible 747Adv Go ahead, I think Airbus would like to put the doubt in Boeing's mind for the 747Adv's competitivity compared to the A380.

your right with the watertanks and stuff like it. BoggyJay, remember, even the firstflight had a TOW of 421 tons. At future flights, they will do lots of testing with M(aximum)TOW.
(Hard landings, RTO, hot and high take of and landing with full payload, and MTOW departure with sudden engine fails etc.)
On route proving flights, the A380 will show the exellent performance, (fuel burning, cabin comfort) and regarding how calm the a/c is flying thru turbulence's.
(It seems, the A380 will provide a new standard in airtravelling, since the a/c flys so calm in turbulent weather conditions)

So, essentially what your saying is that you know this and the route proving hasn't happened yet. How do you know it flies calm in turbulence when that hasn't even been tested yet...?
Props (no airplane related pun intended) for the A380! W00tw00t!
25 RayChuang: I think the big sticking point for CX ordering the A380-800 is can the plane fly a full 555 pax load from LAX to HKG non-stop on a year-round basis. I

30 NoUFO: KC135TopBoom, One of the reasons for test flights is to evaluate fuel burn and to compare estimated performance with reality. There's nothing unusual
31 KC135TopBoom: All I am saying is it is too early in the flight test program to confirm fuel burn. They must establish higher priority things like speed at differen
32 Danny: Really? Because Boeing already claimed 747adv (which they haven't designed yet) will beat it by 19%. Now that is kinda early don't you think?
33 Sebolino: We must admit that Boeing made a really laughable advertisement with that precise 19% economy argument.
34 KC135TopBoom: That is the goal Boeing established for the B-747-ADV. Airbus did the same when the A-380 was just a power point program and called the A-3XX. So wha

52 Magyar: And the weather forecast for today after this news piece: Expect heavy eastward nay-saying over the North Atlantic!
53 Prebennorholm: Untrue. The MD-11 fuel figures were well known long time before it entered service. At that time MDD was already working hard on improvement programs
54 Lightsaber: Alas, a little of the opposite. Current wing theory would require that the A380 have a wingspan about 10% greater than it is for optimal efficiency.

56 B744F: This is all just marketing hype. Didn't the A340 series have the same nonsense with great fuel efficiency??? We see what that turned into.

58 WAH64D: I must say, I'm totally sick of the attitude of some of the Americans on the forum toward the A380. Boeing has stuck it to the European manufacturers
