For a minute, the speed of the aircraft data were contradictory

"For a minute, AF 447 pilots had conflicting evidence on the speed of the aircraft," said the statement released Friday by the Office of Research and Analysis (BEA) in relation to the data contained in the black box flight Air France which fell into the sea on June 1, 2009. That moment of confusion could be decisive and end up causing the death of its 228 crew and passengers, sank in the Atlantic 400 kilometers hopelessly Recife (Brazil).

The mystery about the loss of the Airbus 330 that covered the online Rio de Janeiro-Paris is thus close to resolution. But BEA urges caution to the media and patient associations of relatives of the victims. This is only a partial statement, as were two earlier in 2009, "issued to stop the flow of information approaches that have emerged since May 14 began to study the black boxes of plane." The note, as they call them, chronologically describes the facts of that tragic night in terms of technical parameters and sound recordings that have been in activity in the cabin.

It is "a finding and not an explanation," they insist. So the first hypothesis about what happened "will not be displayed until the release in July the first full official report on the accident," the agency warns. With the same prevention have been expressed this afternoon by Secretary of State for Transport, Thierry Mariani, and industry minister, Nathalie Kosciusko-Morizet, who congratulated the BEA have been able to reconstruct the sequence of the last hours of the flight, the time they have called "serenity" to all parties involved in the case (airline, manufacturer, victims' relatives, media ...) to allow the inquiries continue slowly but surely.

The media frenzy caused in recent days by revelations about the case of 'Der Spiegel' or 'The Wall Street Journal, contrasted with the rush of the manufacturer to send their customers a notice of the accident airplane model (Airbus 330-203) works perfectly is not helping much to the survey that, today, can only establish the following facts: The emergency began with a warning of loss of speed about two hours after the flight took off from Rio de Janeiro, shortly after Captain Dubois briefly left the cockpit to begin his period of rest routine.

Previously, pilots had warned passengers that they were entering a zone of turbulence. The Airbus A330 went up to 11,500 feet, and then began a decline of three and a half minutes, all the while turning from side to side. The smallest of the three drivers ceded control of the passenger plane with more experience one minute before the crash of the device.

The plane did not fall sharply, but was losing altitude for 3 ½ minutes. The black boxes stopped recording at two hours, 14 minutes and 28 seconds. Two minutes before falling to the ocean, one pilot said: "None of the information it already." The BEA has said that researchers have to analyze and validate all data taken since the analysis of the black boxes FDR (flight parameters) and CVR (recording voices and noises in the cabin) is a process "long and laborious.

The agency reported earlier suggesting that the aircraft crossed a storm front minutes before the accident and reading the speedometer was not adequate, and recommended the replacement of speed sensors known as 'pitot' of Thales brand, being unsure of their reliability at high altitude.

Although the data of the boxes seem to point to human error, it seems undeniable that this is associated with a failure of the measuring equipment that could be due to hail the plane was found more than 10,000 feet. "But only after a thorough investigation we will determine the cause of the fire and, above all, make safety recommendations, which is the main mission of the BEA," says the statement.
