Retrieving wreckage from AirAsia Flight To Singapore- no survivors recovered #3

[Dr. Know?]

Just been hounding the Engineers next door. They advised that the 2 units CVR/FDR are housed within the same enclosure they sit on a rack and have 2 knobs on them to detach the unit (hope this is making sense). It's not unusual for them to be come separated. The FDR will advise A/C speed, altitude, bank angle, pressurization to name a few. The CVR will provide the last 0030 minutes of conversation between the CAPT and FO. The Engineers advise that the CVR will still record if you are flying on 1 engine. If an A/C has lost both engines it will not record.

Thanks Emirates, bbm. What? We have to get better than that. just venting.

The Engineers also advised they have software to download and unscramble the parameters from the FDR. The CVR is a completely different ball game. Again you need the software to download, however there are legal boundaries to privacy regarding this. Apparently a regulating body within Indonesia in conjunction with Airbus would analyse the recording.

Has y'all seen this picture of the tail being lifted onto the boat? I'm no expert, but dangling there like that it looks like the only thing holding it together is spit and a prayer...

Agree. If he had lost both engines at altitude you would expect see many, many more pieces of debris. Fingers crossed.

one thing has become clear during this horrific incident:

even IF Indonesia ATC had seen MH370 they would have panicked like Larry Curley & Mo and waited hours to report anyway.....((forgive me -- rant over))

looks a lot better than the sea retrieval!!!

 

[emirates1957]

Yep I'm hearing you. I would love to know where the black box will be sent. Are we going to get a convoluted version. I'm sure Airbus would have to be with the Indonesian regularity body.

this was from earier today: ((took it from previous thread - my post))

If and when the recorders are found and taken to the capital, Jakarta, for analysis, it could take up to two weeks to download data, investigators said, although the information could be accessed in as little as two days if the devices are not badly damaged. ''

Wish I could stay up with the big dogs, but I can't. Thanks all.

Hey Indoneisa, find the people. Please.

Thanks emirates1957 for all your insider knowledge it has been invaluable. Despite this being a horrific tragedy it has been great posting alongside every single one of you. Many Thanks.

Thanks so much newone.

What about the APU? Doesn't that run the CVR on this plane?
That would be a good way to keep it running.
But I know the APU only runs the very basics...

now Indonesia is suggesting there was an explosion due to pressurization

http://www.theguardian.com/world/20...ck-box-from-airasia-flight-but-search-goes-on

"S B Supriyadi, a director with the national search and rescue agency, said that initial analysis of the wreckage so far recovered indicated that the plane exploded on impact with the water.

“It exploded because of the pressure,” he told reporters in Pangkalan Bun town on Borneo island, the search headquarters.

“The cabin was pressurised and before the pressure of the cabin could be adjusted, it went down – boom. That explosion was heard in the area.”

Thanks goes to you guys……I would never know how dig up the invaluable information you come up with.

they know location of CVR

''Suryadi Bambang Supriyadi, the operation coordinator at the National Search and Rescue Agency, says the cockpit voice recorder was located Monday just hours after officials announced the data flight recorder had been brought to the surface.

He says it is stuck under heavy wreckage, and divers are working to lift it."

I'm at home at moment, however I will run it by the Engineers. The APU is an auxiliary power unit. That will provide power/aircon whilst the A/C is on the ground. From my knowledge I wouldn't think it would. Will check tomorrow.

Maybe this is an issue with translation... but WHAT?!
That isn't even a "thing" that happens in plane crashes as far as I know.

In other cases where an aircraft lost both engines, they can use the APU to run the very basics.
I don't know specifics on the A320 though since it's so different. So I thought I'd ask if that's possible. :seeya:

A/C can suffer a gradual depressurisation and you would never know. A rapid depressurisation may occur if there is a hole in the fuselage of the A/C. This will result in loss of pressure, oxy masks will be deployed, and the crew would descend to a safe altitude of 10,000 ft. There would be mist in the cabin, hot liquids would boil over, and their would be debris everywhere though out the cabin. These are drills that are covered all of the time. Pilot's would have also donned their oxy masks. Of course the A/C would explode/break up on impact an cause a loud boom. Not buying the depressurisation event one bit. They would be able to descend from 32 to 10 thousand feet within seconds. On the CVR - you would hear the Capt say something like "this is the Capt emergency descent", which would alert the crew to strap take the nearest seat and don oxy.
