AF447 Plane Accident

Yeah, I don't know really. There's been a hell of a lot of speculation and not many answers. I'm hopeful the investigators will find the answers soon enough, just a matter of time and money really.

I think some sources have said that the ocean depth can reach 14000ft, so if that's how far the FDR and CVR have sunk to, then it will be a difficult recovery. The South African Airways 747 which went down a couple of decades ago over in the Indian Ocean was within waters as deep as 16000ft.

Yeah, we don't have much news at the moment. Hopefully tomorrow as thats when most of the ships are expected to arrive at the area.

"Earlier, Brazil's air force said it had spotted an airplane seat, an orange buoy and signs of fuel in waters with depths of up to 4,800 metres. "

I know they send out a signal but retrieving them is something else.

The "Pourquoi Pas" ("Why Not") will join the hunt currently being carried out by French and Brazilian air force jets hundreds of kilometres off the Brazilian coast, the ecology ministry said in a statement.

The mini-subs it carries can work at depths of up to 6 000m. The ocean area where the plane disappeared has maximum depths of 4 700m, French naval experts said.

That's handy.

The main issue with the Airbus fleet with it all being flyby wire it just killed everything with the electrical short circuit and amongst the black of night and no landmarks the pilots lost all sense of orientation and they spiraled themselves towards the ocean without proper reference to horizon and so the actions they thought they where inputting where not those of what they thought.

That's handy.

The USA Navy have got black boxes from around 10,000 I think.

Yeah, it does come to a question if Airbus "fly-by wire" is good enough for the future.

In a recently released article, an aviation safety consultant said that the wreckage was spread over a couple miles in a rough line, which can indicate the plane came down in several pieces. According to this safety consultant, past wreckages where an aicraft has come down in one piece usually ends up in a circle like pattern. Of course with weather and ocean current pieces get scattered. However he emphasizes the fact that "The big thing to understand right now is we don't know".

With far more questions than answers, everything falls into the category of speculation, though the accident - without definitive clues has the potential to reopen long standing debates about fly-by-wire controls, airliner lightning strike protection, ADIRUs and ETOPS even after millions of hours of safe in-service operation of these technologies.

Thank god by the time in like 2013, there will be a new system into place. So they can track aircraft via satellites.


This is for anyone who's interested in what the future is to bring;

he Next Generation Air Transport System, or Next Gen as it's known, will see the implementation of satellite based aircraft tracking with the GPS, called Automatic Dependent Surveillance - Broadcast ( ADS-B). ADS-B technology transmits the location of the aircraft to within a few hundred feet of accuracy to both ground stations and other aircraft, rather than the 1-2 miles of accuracy with traditional radar.

The FAA plans to roll out Next Gen and ADS-B over almost a decade or longer, with airlines and industry groups pushing regulatory agencies to both move up deadlines for aircraft equipage and provide additional financial incentives to outfit aircraft. The ground-based portion of the system is expected to be deployed by 2013, but aircraft outfitting timelines remain an open question.

All thanks to flightblogger.

The black boxes can be retrieved by a deep sea excavator, but the main concern is to get the excavator transported there and also locating the exact frequency and location of the boxes.

In the report, it said that the Brazillians found traces of kerosene and oil in the ocean. If there was an explosion, wouldnt all of the kerosene have been burnt up and turned into water and carbon whatever?

Also, the fact that the plane emitted automated signals containing information that the plane had lost cabin pressure - I think at this time there was a blow out from the aircraft in which the debris (in this case the seat they found) was ripped from the aircraft along with it just suddenly dropping from the sky.


Thats my assumption anyway. Just gotta hope they find the boxes before their beacons stop working.

Jet fuel can burn for days and it depends on what has happened. The way I see it, I think it blew up in mid-air. But no one can be sure at the moment. It also depends on how it broke up, the A330 even has some fuel in the tail. Plus looking cabin pressure at 35,000ft is bad. If they could, the pilots would try and get it down to about 10,000 where the air is breathable.

Thats my assumption anyway. Just gotta hope they find the boxes before their beacons stop working.

They got about 30 days, so it should be all ok. The first navy ships should be also there doing, so we can actually get a confirmation it is the Air France plane and see if they find anything else.

Could have been me flying home a day earlier on Sunday morning..

Cant wait to watch the Air Crash Investigation to this in a few years

Same, but they might not make one... RIP.
