@ repariit :
Recorders reached Paris on the may the 11 or 12th. That was only 2-3 days!

And there were news, perhaps didn't they reach you :
Press conference @ Le Bourget (BEA) on the 12th morning. Boxes were shown then. The work on them to begin on the 12th afternoon (drying the boxes, testing them... etc.)
New news :p to be released on monday. :)

Nothing strange, IMO. :=

[edit] cross-posting, I see you figuered it by yourself :)

FDR and CVR are 'readable'.

AF447 flight-data and cockpit-voice recorder data is readable

angels 16th May 2011 11:12

Reuters are also saying all that the data from both recorders has been downloaded.

So it seems they've got the lot.

Edited to add that Reuters are now quoting the BEA as saying it will take several weeks to examine the downloaded data. A further interim report will be written and published 'during the summer'.

Excellent news!

I find it simply amazing that after almost 2 years under water, it appears all the data is in tact - What an amazing piece of human engineering these black boxes are.

Not underestimating the hostile environment down there, the most critical part was getting to the bottom in 1 piece, uncompromised. After that I do not believe the time span had much influence anymore, it's solid state memory. After 5 to 10 years+ it likely would have been still OK since the outer shell appears to be quite corrosion resistant.

now let's bet what the recorders will say
 
As you must know, the AF447 flight recorders have been recovered and are legible.
like usual, pilots must be responsible, data to be manipulated if need be. I guess that this time, it will be easy for them, the BEA, since they will probably discover a panic on board (in the cockpit) after the freezing of the pitots, multiple warning, loss of autopilot

Locked door 16th May 2011 19:39

WRT pitot failure.

Don't forget there's a recall drill for unreliable airspeed, and it doesn't call for heroics from the pilots. If all else fails 90% N1 and 2.5 degrees nose up in the cruise will keep you safe in almost any heavy jet.

Basic stuff.

No, lets not.

End of thread.

From Le Figaro website just a few minutes ago. It would appear someone is leaking or spinning that Airbus are in the clear.


INFO LE FIGARO - AF 447 : Airbus mis hors de cause par les boîtes noires
Fabrice Amedeo
16/05/2011 | Mise à jour : 21:41 Réagir Les boites noires ont vite parlé. Selon des sources au gouvernement et des proches de l’enquête interrogées par le Figaro, les premiers éléments extraits des boites noires mettent Airbus hors de cause dans le drame qui a couté la vie à 228 passagers le 1er juin 2009.

Longhitter 16th May 2011 21:15

Full article here:

Le Figaro - France : AF 447 : Airbus semble tre mis hors de cause

Not only does it suggest that Airbus is in the clear, it actually alleges that there is initial fingerpointing in the direction of the crew with the question if it was their actions or AF procedures to blame in the end remaining...

I wonder if it's true and who's leaking the info.

Flight Safety 16th May 2011 21:15

Rubbish, not possible to know this soon. The 24 ACARS messages indicate that something pretty complicated happened, so there's no way to sort it all out this soon.

atakacs 16th May 2011 21:30

@foff


Following operations to open, extract, clean and dry the memory cards from the flight recorders, BEA Safety Investigators were able to download the data over the weekend.These operations were filmed and recorded in their entirety. This was done in the presence of two German investigators from BFU, an American investigator from NTSB, two British investigators from AAIB and two Brazilian investigators from CENIPA, as well as an officer from the French judicial police and a court expert.
That's hell of conspiration me thinks...

BobT 16th May 2011 22:28

Indeed it would be a comprehensive conspiracy.

I assume that downloading the data from the FDR and CVR is not destructive to the original data from the memory devices. This would put a very effective limit on what sorts of games could be played with the data downstream.

But does anyone know what the chain-of-custody is for the original memory devices? Do they come under the control of the French court? Or BEA? Or ??? ?

Nieuport28 16th May 2011 23:15

Don't think the FDR is going to be of use other than to confirm the iced tubes.

The CVR will tell the story. 90% N1 and 2.5 up. Was it ever mentioned?

FruitVegetables 17th May 2011 07:05

And this is the problem:

INFO LE FIGARO - AF 447 : Airbus mis hors de cause par les boîtes noires
Fabrice Amedeo

The guy is a journalist at Le Figaro, he doesn't have the slightest clue about aviation, and his mission in life seems to be to throw mud at Air France. Published a book on the "hidden sides of Air France" which was full of wrong facts, wrong conclusions and overall just lots of rubbish.

I would be the first to call AF a bunch of dangerous cowboys if there are some facts which come from serious sources. But that guy? Forget it. Of course he would spin the story in such a way as to make AF look like imbeciles.

The records in the black boxes clearly makes some of the pprune topics a 3 long years of blablabla of speculation based on nothing, full of wrong theories.
The sickness and limits of the modern internet forums appears here, and, obviously, we will act as nothing happened, and some will even deny what's in the black boxes, against reason, records, science.

Are internet forums full of hearsay, feelings, false judgement, wrong information and their passionate "experts", a travel back to middle age? A time machine?

We need ethics when there is a crash:
FIRST is respect concerning the victims. And only that. It takes a long time.
SECOND is control all the bull**** you die to share here.
THIRD is, when investigators can get something from the datas, learn from it, adapt, evolve.

Internet forums turns pilots into old/non educated middle-age ladies.

You know if you don't like it there are other webpages available. Go look at some kittens perhaps?

KAG 17th May 2011 09:05


You know if you don't like it there are other webpages available
I perfectly know, that's precisely the reason I didn't participate to all this nonsense during all those 3 years, and why when there is a crash the only thing I think about is the victims, instead of explaining everybody how everything happened. We are pilots, not gossip ladies speculating. There is a time for everything, this statement concerns pilots having discussions on internet also.
