AF 447 Flight Recorder Found In the Atlantic
romiz writes "The memory of the flight recorder for the Air France 447 flight from Rio de Janeiro to Paris, crashed on June 1st 2009, has been found on the seabed of the Atlantic Ocean, and brought back to the surface in good shape. This is the data recorder, which saves the flight parameters. The search is still continuing in hope of finding the voice recorder containing the sounds recorded in the plane's cockpit."
All the way.
The memory of the flight recorder for the Air France 447 flight from Rio de Janeiro to Paris, crashed on June 1st 2009, has been found on the seabed of the Atlantic Ocean...
When you look at the twisted mass of wreckage the flight recorder came from, finding the data unit is a miracle. Thousands of feet underwater, working remotely in a pile of twisted metal and they find a little memory unit. I have trouble finding my car keys some days.

Airbus already records remotely some telemetry data but not voice data.

They'll get paid by Boeing for patent infringement when the 787 starts deep see exploration.
Does somebody know why it's so hard for them to find it? I would assume that it's properly secured against crashes, and has a GPS/transmitter on board? What causes this to be so hard?
;-)
Hmm, how about from now on they'll just box an iPhone; then at least you know for sure that the location is known

I would say: the bandwidth you need grows proportionally with the amount of data you transfer. maybe thats the reason. i imagine you can send the most important telemetry data every 10sec using a rate of 300bps but to record pilot and copilot in high quality i think you will need 100 times more. if you have to use SW or satellite, you will be limited.
The fact that they found this box on the bottom of the Atlantic long after it's beacon died out and the fact that it's in good shape is just amazing. Let's hope they can figure out what happened.
The pitot tubes on that Airbus model are notoriously prone to icing. Many Air France flights have had documented hazards due to the inability of the plane to sense and maintain airspeed.
The French government has already opened a criminal case over the crash.
Perhaps it is YOU who should be more informed.
I want to delete my account but Slashdot doesn't allow it.
turn in your nerd credentials for thinking that would work
additionally, flight data recorders do send out a ping for 30 days:

intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Because it was 4km under water and radio transmission and reception don't work there? You can't get GPS signals and radio beacons don't work there. Even if you could, the batteries won't last the months it took them to get a ROV there to pick it up.
I was promised a flying car. Where is my flying car?
Or have two recorders that both do voice and data, to provide redundancy. But remember that the civil aviation regulation is still stuck perhaps not in the biplane era, but somewhere close.

Not to mention you'd need the bandwidth on the satellite system to deal with every commercial airliner in the air simultaneously.
They always open criminal cases on crashes, just in case they're not an accident.
I was in Dublin, Ireland, when the Euro currency came in.
Due to the different ways each European language handles plurals, it was decided not to have a different word for the plural. This was emphasised in the conversion literature.
So half of 7 Euro would be 3 Euro 50 cent.
And of course these figures have to be normalized with regards to the number of flight-hours ecah company has. Perhaps there are more Boeing planes in the air than there are planes built by Tupolev?

Why don't they put the voice recorder in the same box, that way if you find one you find them both? For that matter, why don't they put two identical black boxes in the plane, that way searchers have a higher chance of finding at least one of them?
There seem to be fewer Airbus aircraft than Boeing, so these numbers need normalising I guess...
From http://en.wikipedia.org/wiki/Competition_between_Airbus_and_Boeing (Deliveries summed)...
Airbus 1989-2011: 6175
Boeing 1989-2011: 9429
Why if you have 2 flight recorders do they not have the voice replicate to the data and the data to the voice ... that way it you find one you have the complete data set.
I know "crazy talk" but I'm a storage bod and it irks me when people lose VERY important data!

Interesting that this was attached to the main unit with 4 bolts which sheared off..
Planes can transmit "in real time" much more information than what they record by using the same satellites used for those fancy global radio phones. That way, everything is captured at the moment it happens, including coordinates, which makes the plane easier to find.
Something tells me the world airline safety experts are already debating the update of recorders to offer redundant multiple storage of ALL data from a plane in case of a crash.
Given the nature of storage density these days, I really doubt it would cost much more or take up much more room to have redundant storage. It would seem to require primarily a couple extra cables and connectors.

Help! Help! I'm being repressed!
There were somewhere about 5000 flights in the air at any one time. The bandwidth for telemetry would be about 64k per aircraft (voice can be pared down to under 32k and 32k for SCADA-type telemetry would be more than sufficient). That's 320 Mbps to handle every aircraft on the planet simultaneously. It would be cheaper to set aside something for a terrestrial network for the airplanes over densely populated areas (US domestic, and other similar routes), but even without that, there are ways to do it that aren't that much on the global scale. Perhaps they could just buy Iridium and run the telemetry/voice live over that. That would be cheaper than building something similar. But the capability to serve the network over GEO satellites exists today as well, just not cheap. The recurring on it would be about a billion a month.

They also used some needles made of bone, so the magnet was useless. Dunking in water did the trick, hay floats bone sinks.
Anything that sticks out on any airplane is prone to icing. This has nothing to do with Airbus, but with simple physics.....
...richie - It is a good day to code.
The recorder has pingers in it, and even if they go dead, sidescan sonar makes it little more than a matter of time.

Why don't passenger planes have parachutes under every seat?
Answers along the lines of "because laypeople are stupid hurr" need not apply. Is there good reason which doesn't invoke an argument by authority, point out that 30k feet is too high, or remark that there probably won't be enough time for everyone to get out this way?
Enjoy your rat-feces infested ancient Boeing planes operated by Delta. But don't pick too hard at the chewing gum under the seat because it's holding the plane together.

"We have access to virtually every kind of information. I found your name on the passenger list of the [plane] that crashed." Arthur was astonished. "You mean they knew about the crash?" "Well, of course they knew. You don't have a whole [airplane disappear into the Atlantic] without someone knowing about it.' "But you mean, they knew where it had happened? They knew I'd survived?' "Yes." "But nobody's ever been to look or search or rescue. There's been absolutely nothing." "Well there wouldn't be. It's a whole complicated [airliner manufacturing] thing. They just bury the whole thing. Pretend it never happened. The [airliner] business is completely screwy now. You know they've reintroduced the death penalty for [airliner manufacturing] company directors?' "Really?" said Arthur. "No I didn't. For what offence?' Trillian frowned. "What do you mean, offence?" "I see."
Would that be aleph-naught plus one, of omega plus one? Quite different concepts, you know.
I'm in a totally different division, can't claim any credit.

There is more than one microphone on any voice recorder. There may be as many as five on some aircraft. Also, degrading the sound quality by lowering the data rate can mask other sounds that are even more critical than a flight crews last words.

1) This would help in surprisingly few crashes. Most crashes take place during "normal" takeoffs and landings.
2) Over the ocean, you'd need a parachute AND a life raft. (A dinky little inflatable life jacket isn't going to cut the mustard on the open ocean where hundreds of your fellow passengers are spread over miles and miles of (likely rough) water with NO floating aircraft bits to hold on to. And that's if you survive to get in the raft. Good luck having more than a few untrained people successfully ditch the parachute, swim to the surface, and find their life raft (while fully clothed) before they drown.
3) Over land, there is usually plenty of time to glide to an alternate airport (or smooth patch of ground.) If you have land smooth (and soft) enough to land untrained people in a parachute, it should be good enough to land the plane.
4) If the plane starts to break up, stall due to icing, etc., it would be in no condition to evacuate via parachute, as it almost certainly is not in smooth controlled flight at the time.
5) The plane is going too fast.
6) You can only evac through exits where your tumbling body isn't going to hit anything like the wing or tail.
7) You can't start the evac until the plane hits 10,000 ft or so. Before that the doors can't even open because of the pressure difference, and even if they could, you'd pass out due to hypoxia. (Bad Hollywood movies notwithstanding.)
8) Parachutes are HEAVY. You'd chop the passenger capacity of the aircraft by quite a bit by supplying everybody with a parachute.
