French say it is too early to discover reasons for the 24 signs of failure of Airbus
The Airbus A330-200 of Air France who disappeared in the Atlantic Ocean in the early hours of Monday delivered 24 signs of deficiencies in its
systems during the four minutes prior to your departure area of the radar tracking, French researchers reported today.
This information, first disclosed by the Office of Research and Analysis (BEA, the French acronym) gives more reliable clues about what may have
occurred, although it is still "premature" to conclude they were the causes of the accident.
The director of BEA, Paul-Louis Arslanian, who spoke to the press for the second time since the tragedy, was indicative of whether or deny the
conclusions to reinforce a hypothesis than any other, being careful to show only the data confirmed.
"It is too early to know the causes of the accident," he said at the same time it eliminated any and all "dangerous conclusion."
Arslanian was indicative that the state is "premature" to say the reasons that caused these problems and if they caused the accident.
He does not completely discarded the hypothesis of a terrorist attack, but "not very coherent" from the information you have.
Many details still to be built - in particular, the black box of the plane - which is necessary to know what happened in the middle of the ocean with
the AF447 flight that was the route between Paris and Rio de Janeiro and disappeared without a trace with 228 occupants on board.
The only available signals are automatically issued and collected by the aircraft radar.
From these, it is known that the flight passed with normality until 23.10 on Sunday (schedule of Brasília), four minutes before the plane leaves the
area of monitoring radars Brazilians.
This is where the signs of deficiencies in the systems of the A330 have been fired. At least 24 issues were recorded, 14 of them between 23.10 and
23h11 de Brasília.
In particular, these signals show "inconsistencies" in the data recorded by sensors speed. The A-330 has three facilities in the genus and, when
the differences between what each measure is high, a warning signal is issued.
Therefore, some electrical systems, including the autopilot and the self, no longer work, something that happened that night in AF447. However, do
not discard the hypothesis that the crew has turned off these features on a voluntary basis.
It is not known whether returned to work later, when the plane was already in the intermediate gray area of the ocean, out of reach of radar and
Brazilian outside the radius of action of Africa.
This type of anomaly has been previously registered in other A330, said the head of the BEA, which has led Airbus to study the changes in the sensors
to make them safer.
Moreover, the director of BEA spoke to the press along with the deputy director of the French meteorological service, Alain ratio, which shows the
influence that the weather is still studied.
However, this path does not reveal anything extraordinary because, according Ratio, conditions were recorded for a normal month of June in the
Atlantic region, place of confluence of winds that cause storms.
The officer reported that by observing weather conditions were worse on other days next to last Monday and that at the time of the accident was not
particularly exceptional records of storms.
However, the researchers demonstrate that the AF447 that area may have experienced "always difficult for pilots" without the help of some automated
systems, while it did not hit the hammer on this hypothesis.
More data are still missing and, therefore, the black-boxes are considered essential, which explains the procedures for starting your location.
To find them, and all media submitted to date by Brazil and France, including a nuclear submarine, where acoustic systems sum lent by the United
States and will be shipped in two French vessels.
With them, the goal is traced in "more rapid and systematic" the ocean floor in search of black-boxes, which for almost 30 days before issue
signals to silence forever.
