It is certainly putting in the hours today. Take off at 07:30 ish and it is now 17:30 ish and GiGi is still trundling up and down the bay of Biscay.

It will be the longest test flight so far.

I see AIB9GG the last time in Toulouse at 07:43 UTC still not on the runway and than she appears near Marmande at 08:09 UTC. So I will keep in my spreadsheet 07:50 UTC as take off time.

Thanks guys for all the work with the time keeping, we are now at 20% of the flight test program being done and there is one year to EIS, seems doable.

Evrard said on a briefing during the spring that "we now enter flight testing, that is something we know how to do" or similar. It was in the context of the challenges they saw with the supply chain producing the different sections in the new technology. What one can appreciate with Evrard and Bregier is that there is very little bull talk, when they say they are cautious that is accepted and now when they show more confidence in a phase one can start to thrust them, refreshing    .

Quoting bycac (Reply 11):

To complete AIB89WB :

MSN001 still carries all the tufting and the Vmu protection. At the same time a few cameras seems to have been taken off. IMO this is to have these means for upcoming tests, we know that tests with on-glued plastic ice formations shall be made. Landing tests with ice on wings is very important to do, ice can form very quickly unknowingly during landing and one want to know how the bird reacts. Does she warn and stall slowly, violently complaining about the mistreatment while gracefully descending a bit faster then usual or will she say virtually nothing, then stall asymmetrically and go down over one of the wings like a piano?   

It can seem a bit un-probable but stalling with a disturbed leading edge can be fishy, it is very hard to predict what happens. If the stall instead happens on the HTP it is even worse, stall of the HTP at landing means you have a very strong forward moment and the frame tips forward violently and is very hard to save. The same goes for start but the frame is a bit less loaded in the start config and it should be a bit less violent what happens.

So there is every reason to want to know what happens with the flow in the BIG windtunnel and how close to the edge you are sailing, that is why all these means are kept for icing trials. The number of frames which has gone down due to icing are to many   .

They are both stunning  , one can clearly see the flow disturbance of the nacelle and pylon and the vortex that the nacelle strake creates (the high frequency patchy pattern in the wake damp) if one goes to the higher res Flickr originals.

One can also see that the inner spoiler gaps is clearly lager then the no 2 spoiler gap. All tweaked by MSN001 during the Augusts-September high lift tests. All is apparently not frozen for the start configs (ref the recent briefing), I can imagine that the Vmu data can still be complemented (protection mat still there) and things can still find their way from these trials to tweaks angles on the slats/flaps/spoilers for start. It is not excluded that the icing trials can also bring tweaks.

If Wi Bi is supposed to do half of the program, 1.250 hour, and keeps to a similar schedule the next month, she could be finished in six month. The program is "flying" along.

Looking at these nice pictures again they are also a good yardstick for Flaps 3 vs Flaps 2. The top one, MSN001, starts with Flaps 3 ( flap tip almost touches the air outlet on the wing fairing) and the bottom one, MSN003 with Flaps 2, just clears the step in the fairing.

Has the either A350 taken a lightning strike yet? I know in the early test flying they were anxious it did not happen, is that still the case? Although the airframe has been designed to withstand it, maybe it would play havoc with the test equipment.

There are a few lightning discharges recording around Southern France today, maybe that's why the raccoons are no-show.

There's a good summary of the test program from 21 Oct that I have missed somehow, saw it as a link with the MSN005 article:

http://www.flightglobal.com/news/art...tter-test-beckons-for-a350-391935/

Here some excerps:

""
MSN1 also carried out minimum-unstick tests on 26 September, during flight 57.

Airbus vice-president of flight-test regulation Hugues van der Stichel says the test, at Paris Vatry, involved accelerating the A350 to around 80kt – as quickly as possible, to maximise the available remaining runway – before reducing power and applying maximum pitch up.

The take-off is performed offset from the runway centreline, to avoid striking lights as the rear fuselage makes contact, while the pitch is not altered until the aircraft has reached sufficient height, about 300ft, to clear ground effect.

“It’s a risky test that could easily damage the aircraft,” says A350 programme chief Didier Evrard. “Fortunately we have excellent pilots.”

While MSN1 conducted the minimum-unstick take-off, MSN3 was also equipped with a tail-skid mount, as a precaution, in case it was required to perform the same test.

“We were not sure how much time it would take to get to this [point],” says Evrard, adding that the test might have needed repeating.
""

Wonder why they reduce power, is that because they would overrun Vlmu otherwise?


Further:

""
Van der Stichel says the free flutter test is the next major aerodynamic check. “We know it [will meet expectations],” he says. “We have to demonstrate it.”

Airbus is yet to perform formal fuel-burn performance tests but Evrard is confident. “There’s no reason it won’t be in line with our forecasts,” he says.
""

So no worries for the fuel burn on the aircraft anymore, the 3t overweight set them back about 1.2-1.5% but that is fixed by the engines (right now -0.5% according to Zeke and might go to -2% at EIS) and probably by aero as well, the aero guys normally keep the odd % to themselves  .

I read this article in Flight last week. There is some interesting facts.

Quoting ferpe (Reply 49):

I would assume they need to reduce power so they can ease the back-end onto the deck without causing damage and stopping her from lifting off. They want to control her rather then the other way round. Once at 80kts and the arse on the deck power would be increased (to T/O power?) and then your unstick speed will be verified. It must be fairly difficult keeping pitch the same until 300ft under the heat of the moment. Something I think didn't happen with the poor A380 when they scraped the underneath past the skid!

Evrard's words on fuel burn are quite interesting. I guess while they were very busy with all the other tests, they might have unintentionally looked to the fuel flow display a few times . My suspicion is they are very confident but will not say anything specifically until the dedicated fuel burn runs/ early long haul flights are completed.

I believe testing is a bit ahead of schedule. If I'm not mistaken, the plan was to have around 440 hours at the end of October but they are at 500 hours already.

My suspicion is they are very confident but will not say anything specifically until the dedicated fuel burn runs/ early long haul flights are completed.

Add to this that MSN001 has been rather aerodynamically dirty with all the test equipment glued on to the body here and there and everywhere. How it will perform in a vlean state must under such conditions be very much guesswork.

Correct and interesting indeed...

I guess it also means that we could see less flights now... MSN1 has not been flying for about a week now (31st Oct.) and MSN3 last flight was last Saturday (2nd Nov.)

One explanation could be that both aircraft are being readied for the next phases, like: Hot/Cold weather, (natural) Icing, "Hot and High" and various certification flights (with EASA/FAA observers??)
These flights will be harder to track I guess, La Paz, Bolivia (Hot and High) doesn't have any ADS/B coverage on FR24 it appears, and probably the coverage at Iqualuit, Canada (Cold Weather) isn't optimal either.

Quoting ferpe (Reply 49):
Wonder why they reduce power, is that because they would overrun Vlmu otherwise?

Because Vmu needs to be established at the T/W for one engine inoperative but it is OK to use all engines operative at the appropriate thrust level to simulate the correct T/W.

See AC 25-7C http://www.faa.gov/documentLibrary/m...dvisory_Circular/AC%2025-7C%20.pdf

From Pages 24 & 25

(d) In lieu of conducting one-engine-inoperative VMU tests, the applicant may
conduct all-engines-operating VMU tests if all pertinent factors that would be associated with an
actual one-engine-inoperative VMU test are simulated or otherwise taken into account. To take
into account all pertinent factors, it may be necessary to adjust the resulting VMU test values
analytically. The factors to be accounted for should include at least the following:

1. Thrust/weight ratio for the one-engine-inoperative range.

(e) The number of VMU tests needed may be minimized by testing only the
critical all-engines-operating and one-engine-inoperative thrust/weight ratios, provided the VMU
speeds determined at these critical conditions are used for the range of thrust/weights appropriate
to the all-engines-operating and one-engine-inoperative configurations. The critical
thrust/weight is established by correcting, to the VMU speed, the thrust that results in the airplane
achieving its limiting one-engine-inoperative climb gradient at the normally scheduled speed and
in the appropriate configuration.

There's more if you care to read the whole section but no need to fill up too much space here.

edit was to correct "all engines inoperative" to "all engines operative"

Vmu with "all engines inoperative" is pretty hard to achieve.

Airbus probably wouldn't be too keen on interrupting their test schedule, yet on the other hand they could still incorporate the flight time. And as it's been mentioned that they may be running ahead of schedule, any chance of a raccoon heading over to Dubai for a day? The airshow is set to begin in about two weeks' time.

Maybe. But I am expecting new orders for the -1000. Maybe also some conversions from previously ordered A350-900's. But since the A350-1000 is not flying yet, they better stay on track with the flight test program. They are ahead of schedule. it can not hurt to keep that situation the way it is.  .

So I would not o to Dubai with the A350 if I were Airbus, and would keep on pushing the flight test campaign. Unless something really big is to be celebrated by Airbus. But the Dubai Air Show this year will most likely be Boeings party with the launch of the B777-X.

The Dubai air show will be mainly concentrated around the launch of the 777X indeed, but it would be weird if Airbus doesn't announce any nice deals too. Emirates ordering 100+ 777X aircraft is perhaps the worst kept secret in aviation - it was mentioned in 2012 for the first time - thus Airbus had about a year the time to prepare at least a few nice surprises.

That's the time. It was on the apron on the south, from where most test flights seem to origin (close to Saint-Martin-du-Touch), I guess, but the map was not much enlarged when I saw it.

I think Airbus will handle it like Le Bourget. They are planning for it but no public commitment until GG is on it's way to Dubai.
Especially if everybody is waiting for a 777-X sales show, JL would be more than happy to come to this party with his A350, even when he is not invited.
In addition:
a) the flying time to Dubai is still useful time for the test program, so no delay there
b) I think the risk for the A350 to have any glitches on this tour to Dubai is minimal, because we already got the confirmation about the current reliability from many sources (and we can see it nearly every day at FR24).

BTW: AIB15GG is preparing for today's flight.

Good thinking indeed, If I were Airbus I wouldn't commit to things that might not be possible.. Even with the reliability of the A350. MSN1 (WB) hasn't been flying for a week now, so if she's in (scheduled?) maintenance taking MSN3 to Dubai would stop the entire program...

It seems that the risk of problems popping up that might prevent both Gigi AND WB going to Dubai is minimal. However, if such a problem should appear and a promised show of the aircraft must be canceled the loss of prestige would be humungous. So - a small risk of losing a lot!

I assume this low speed/altitude testing will come to an end soon, MSN3 is the one scheduled for the hot weather trials which should start very soon.

If Airbus will do the hot weather campaign in the Middle East during the coming weeks, they might fly it to the air show.

Aren't they about to enter artificial icing trials, not natural icing trials (the latter being part of the development phase in the timetable)? First milestone in the development phase is, "A/C aero configuration freeze". If they need the configuration freeze for the artificial icing trials, then they have entered Development phase.

You would have to frozen everything, just have all your configurations very well documented and understood. If you have frozen your configs you have less test cases to check so it is an advantage but not a necessity. You take a well known config, say start config 2 (with slats and first level of flap deployment) and then you fly this config at low altitude (high enough to be able to recover safely from stall) in such a way to simulate start with one and two engines with ice on the wings. You would also lower the speeds until you have stall on the wings to know what margins you have when flying normal speeds (if any).

Icing trials means you have to start with the ice on the wings, it means starting with higher speeds then normal, this we should be able to see as well as the ice formations glued to the wings leading edge when they land. They would also do the ladings at higher speed then normal. Icing trials is a bit fishy as your stall warning does not take the ice into account, it is based critical alfa angle for a clean wing so you can have stall before the stall warning sets it.

Stall warning angle is often adjusted for wing icing on modern airplanes. When the ice protection system is turned on, stall warning angle of attack is reset to a lower alpha. Since the ice protection system is switched on automatically by the ice detector for some airplanes, this results in an automatic stall warning reset in icing conditions.

During initial flight testing with artificial or natural ice, the lower stall warning angle may not be final, but an estimated value may be available based on wind tunnel testing.

That might be the case but as a test pilot I would not care to much about the stall warning set by such data, the important thing is to feel when the wing start to give away. The A350 wing has the droop nose which should give in well before the outer slatted wing, also with ice so there should be natural buffet to tell when the stall comes with good roll stability.

I am a little intrigued to see that the horizontal part of the winglet outside of the slats are quite long, this means this part of the wing does not have a slat to delay any separation and not the increasing leading edge angle to the stream like the curved part have thus creating a vortice flow at higher angle of attack. This part should stall well before the rest of the wing especially with artificial ice on it. As there is not ailerons behind it might not affect roll stability to much but wing tip stall is something one would normally like to avoid. I would guess there is not deice there as well (at least no pneumatic one), a bit strange IMO.

While I don't have any evidence, I'm convinced that the aero configuration will have to be frozen before starting the artificial icing trials.

I think it's more of an easy task for an airframe manufacturer: Just put three moveable scales (at least for an A350) under the gears and sum it up.

Quoting AustrianZRH (Reply 129):

Theoretically yes.

In practice friction in the strut, gas pressure, temperature, and a number of other variables make it difficult to get any real accuracy. It also has the minor issue of not "weighing" the gear below the strut. There have been numerous proposals, and a few mostly unsuccessful attempts to do that on an operational basis, to determine (directly) the weight and balance of an aircraft.

Airliner sized scales are not actually all that complex or expensive. Not to mention fairly easy to calibrate. A common type looks like a set of hydraulic jacks with a force transducers screwed into the tops. For example:

The take off is not on FR24 (not sure if playbacks are possible on Toulouse Radar), but she pops up south of Toulouse around 9:15 UTC and it looks like she took off to the north, so must have been in the air for a few minutes at that time.

Whatever the current test is, they are pushing the raccoon by doing some nice roller coasters.

My guess would be stalls with (artificial) icing...
I somehow think that flutter tests have already been done and that the pictures were released afterwards by Airbus, in October there were multiple flights where MSN1 was diving with 7000+ fpm at 550+ knots speeds.

How close is that to the speed at which an aircraft that had lost pressurization would come down to breathable atmosphere?

edit: by the way, clicking on 93WB, I only see some kind of a very large right-hand circuit around TLS, some kind of flyby, and now a shorter left-hand circuit…

Based on what was said on the EADS q3 conference call, the next big a350 update is likely to be on the investor day (I think the global investor forum)- update on technical progress, flight test info etc.

I would think so too.. Interestingly it now appears, based on the EADS guidance and the information given in the analyst call, that there is higher spending on the test aircraft and the initial customer aircraft. I guess we can discuss the implications in the prototypes thread.

I would dearly bwiush we could see pics of the left side of WB as the wedges seem to be on that side.
On this picture, there is apparently an addition to the outer slat.

There is artificial ice on all leading edges on MSN001 visible on the first picture, you have to go to the flicker archive, right click and choose highest resolution, then you clearly see it. There is a grey area on the middle on the wing slat, hard to say if this an but of LE where there is no ice or not but the rest clearly all have black leading edge artificial ice. Wonder how she stall if one kicks a bit of side rudder

Both aircraft have flow for only three days this week and no sign of any activity today. Either it's been one of those rare off weeks for the a350 test program or perhaps there is a small chance msn 3 could be getting ready for a flight to DXB shortly?

I understand it for MSN0001 as it has been flying with the artificial ice. I am sure there is a lot of data to crunch for that - and maybe a software upgrade.

Does anyone have any idea how long the artificial ice program is likely to last?

MSN0003 it is not so clear why the slower rate this week. It may well be that it is off to Dubai - but I thought Airbus said they would be doing a tour of the A350 factories before that. If so Dubai is out. Mind you I am sure Leahy would really like the raccoon to make an appearance.

G´day

For the airshow Airbus would surely not show their newest baby in eurowhite. So they are likely putting on some stickers or even do some paintwork. We will see soon

But there has to be something wrong... the Raccoon is still circling over France instead of going to the fare east. I thought Dubai is calling...  

But maybe the special stickers on GG are not dry yet... and we only have the first day of the Air Show.
