This excellent article gives an in-depths idea on the current flight-test program of the A 380.
Rare to find a public statement from the flight-test pilots on the current problems and issues .

Quote from the article: Fernando Alonso, vice president Flight Test division at Airbus and member of the crew who flew the A380 on its maiden flight

Alonso continues, “Personally, I think we could get the flight control system certificated in its present state.



Quote:
On the engines, the engineers' main worry was excessive oil consumption early on, which is why the next A380's will have a slightly modified Trent design.



Quote:
At a velocity of only 138kt (256km/h) the reference velocity VRef is four knots (7.4km/h) less than expected. The A380 lands at a lower speed than an A340-600.



Quote:
the landing gear was put under maximum load during some taxi tests on 25 June. [...] An extra hazard was posed by the fact that the rear axes of the two six-wheel fuselage landing gears, which are normally steerable, had been locked in position.

So much for those famous pictures.

Quote:
In test operations from Toulouse, however, MSN001 is already flying with the regular wake turbulence distances for the “heavy” category between normal scheduled services.



Quote:
up to now spoilers 3, 4 and 5, when extended, have been generating air vortices that cause the elevator to vibrate strongly when they hit the horizontal stabiliser. For this reason, the first elevator rib is to be strengthened.



Quote:
However, we did misjudge the amount of work involved on the wiring. The scale of individual customer special requirements surprised us. Now we are having to do the wiring with all the cable harnesses for many different customer versions in parallel. [...] Because of that, at the beginning we had sections in final assembly without the full system equipment for the cabin.”

MSN002 is the aircraft earmarked to undergo the notorious evacuation tests with the maximum number of seats fitted and 873 passengers on board in Hamburg at the beginning of 2006.

Bloody brilliant report!
I had been expecting a couple of major issues, but seeing lots of small ones was in a way, kind of reassuring. Although seeing that thing doing Mach 0.96 would be wild!
I wonder where they're going to be doing the hot weather testing in Australia?

Thanks for the report. I'm pleased to see the testing progressing so well. It's going to be something to see those babies flying around. Are they going to undertake an A380 North American tour soon?

Cheers, Ralph

Now being a newbie, and having now real background knowledge, is this suggesting that Airbus didn't take into account PTV's and internet access, or is it simply more wiring because they want the maximum number of seats?
Surely not?

No, it is a case of the airlines having many options and features to choose from, so that makes it all the more complex. There isn't much compatability betwen what individual airlines order in many cases, so different wiring and cabling arrangements have to be scratch built for them.

The technology is also changing literally from week to week. Designing aircraft systems in the current explosive technology climate must be an exciting place to be at.

I am sure that Aviaton Week will have a pilot report as well eventually. I am curious to hear how the airplane flies from their perspective. I will also be curious to hear how it compares with other airplanes from line pilots. Some are real popular: B737, B777 and others such as the MD-11 are not.

Actually I do not think this is a big factor. Because each aircraft and system configuration must be certified, I believe that Airbus and its customers will select proven systems that they can get through certification and are widely servicable rather than getting what is the latest and the greatest technology.

Quoting Airbus Info (Reply 1):
An extra hazard was posed by the fact that the rear axes of the two six-wheel fuselage landing gears, which are normally steerable, had been locked in position. Despite this, all the landing gear legs held up, all the maltreated tyres stayed on their wheel rims and the test was deemed to have been passed.

Wasn't there a recent thread claiming the tyres didn't stay on the rims??

Ryan air would be the only A380 customer who request no seats, because they'll be asking passengers to bring their own. Apparently their flight crews have to arrive early to ensure they get a seat! Big grin

"Before that, MSN001 will visit Sydney on 16 November as part of the celebrations to mark the 75th anniversary of Qantas"

Lets hope these dates hold out! I am really looking forward to its visit, not long left.

Yes, Melbourne Tullamarine too!!! Melbourne has some resident a.netters who will be eager to see the AirBeast! I guess its too early to know what the exact ETA's are for the aussie tour. But i'm sure someone will find out. I think the order of play is Sydney first, Melbourne then Brisbane.  Smile

this is the same trouble Mercedes Benz has with their cars. They offer so many ways to option the car that for an E-Klasse, there are over 200 different possible Dash configurations that will go into the car (based on color, drive, electronics, etc.), and they all go on the same line and must be exactly matched to each VIN.

Compared to many Japanese makes which have 3-10 configurations for many models, with radios added at the port instead of integrated in the overall design, it adds cost and takes more time to do a custom/semi-custom job. But ultimately, it's what the airline/car buyer demands that drives the market.

Ok, wow you a very short sighted. Geesh, if Airbus thought like you they would have half the sales. Since there hasn't been a US airline adopt the A380, that alone, Airbus has a reason to fly the A380 here in the US.

There will be probably be more A380 heading to the US destinations than any other country when this bird flies.

but anyhew, had to get that out of my system. Great article - just happy to hear some real news and progress.



Airbus or Boeing - it's all good to me!

You don't recall the gyms, duty free shops, massage parlors, lounges and everything else imaginable? From my perspective, that would be customer customization, so I would be willing to be a source for the Glideslope.

That was just early PR and not related to the interior customisation problems they've had. Installing a shop or a massage parlor would not be really complex, btw.

Of course it was PR, but I think that is what Glideslope was referring to, not the actual lack of engineering resources at Airbus.

Pulling a couple rows of seats out of an airplane isn't complex either, if you do one forward and one aft... but the new cabin config still needs to be certified.

Sure, but certification isn't the cause for Airbus' interior problems, right?

It may certainly be part of the problem, as each config needs to be certified, and the organization within Airbus that has been granted that authority, may simply not have had the resources.

Of course it could have nothing to do with it, as that part of Airbus could be over staffed.

I don't believe that the whole delay is do to installing wiring after the major components were delivered without, as this wouldn't affect the first 40 deliveries.

I do know that every different galley, seat, closet, business center installation and so forth do need to be certified to meet the 16G rule, and this would be a more time consuming task then running some digital busses to different areas of the airplane and reprogramming the lighting and service systems. Then there are burn tests for interior furnishings and so forth, which are required for certification.

But in a nut shell.... who knows  Smile
