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

[SouthAussie]

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.

Yes, it looks as though the National Transportation Safety Committee (of Indonesia) is the primary investigative body.

Madjono Siswosuwarno, the main investigator at the National Transportation Safety Committee, told Reuters ...... "The download is easy, probably one day. But the reading is more difficult ... could take two weeks to one month," Siswosuwarno said.

I don't know how capable they are of reading the data. From 2009 to 2011 Australia helped them with the data from several Indonesian aircraft crashes, at their request. It seems they will need someone to help them, unless they have greatly upskilled themselves since 2011. You'd think that Singapore would be the natural choice, seeing as the plane was headed for Singapore and had a Singaporean on it.

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.

Oh I know that.
What I believe they were trying to say...

Is that the plane WAS still pressurized when it hit the water.
And that BECAUSE the plane is pressurized...
It exploded upon impact... because it didn't have time to depressurize.
So basically if the pilots had depressurized before they hit the water - it wouldn't have gone boom. :facepalm:

So basically the same concept as an oxygen tank near fire.
That just isn't how pressurization works on a plane.

Yes, planes break apart and/or crash due to depressurization. That can happen.
Especially if a cargo door, (Turkish Air 981) or piece of the fuselage is ripped off.

But planes exploding because they are pressurized? Is just not a thing.
Maybe it's something lost in translation, but that is how I took it. :twocents:

Thanks SA, well I guess they should be old pro's by now. Several Pilot's I have spoken to, suggested/thought that a member from Airbus would/should be present. Will dig a little further.

Aaarh I see what your saying. Will get further information from the boys tomorrow.

That sounds crazy right?
Going boom because the plane is pressurized? :dunno:

 

[emirates1957]

Your right it does sound crazy.

Okay good because I totally have pregnancy brain.
Put the saltines in the fridge, the milk in the freezer and the Sprite in the pantry.
So I wanted to make sure I was not missing something here too!

Interested to see what the boys say. :seeya:

 

[SeriouslySearching]

I am glad they found at least one of the black boxes! Moving along quickly.

Exploded on impact because the plane was still pressurized? I don't buy it. I do think the plane broke up, but look at what has come up so far and there is zero indication of an explosion of any kind. Not seeing any black soot-like markings and the pieces are not ripped along the edges. Doesn't make sense.

Hate to tell you I have pregnancy brain some 26 years later. I put the remote in the freezer the other day. All the best with bubby.

So they have part of the plane plopped out on the street like a tourist attraction with people wandering all around it? :thud: What the....[video=twitter;554541757417787392]https://twitter.com/NST_Online/status/554541757417787392?lang=en[/video]

I do see some police tape, but it is curious. The guy with the backpack could be legit, but he rather looks like some random person taking a closer look. We are so used to the NTSB and the professionalism they show when they recover a crashed plane perhaps we have to understand in that part of the world...things are a lot more lax. Maybe they feel like nothing else can happen to an already crashed piece of an airplane so security isn't a huge priority or something?

 

[MsFacetious]

What part of the plane is THAT? It doesn't look like the tail?
Then again that tail was so obliterated that maybe it is. :dunno:

An example of a gradual depressurization is the golfer Payne Stewart's plane crash. They all passed out and just flew until their plane crashed.

RIP Payne Stewart et al

RIP Payne Stewart et al

I know...loved that guy.

this will help to identify the ''debris'' compared to what Snoods posted.

You can see the door ''cutaway'' in the rear of the plane next to the windows
