air france 447 black box of information released, the aircraft stall crash

Investigation of the French Civil Aviation Safety Authority released a 27 brief flight data shows that Air France flight AF447 A330-203 aircraft on the evening of 31 May 2009 from Brazil to the French capital Paris, 3 and a half in the take-off hours after the turbulence encounter, then climb the stall and for a time a few minutes later the plane crashed into the Atlantic Ocean.
Investigation of the French Civil Aviation Safety Authority aircraft in the interpretation of accident "black box" data records, said the plane hit turbulence, the aircraft instrument displays the speed and the speed of backup equipment records are inconsistent, then close the aircraft autopilot. Rest in the cabin when the captain (pilot flying can be a long rest rotation), aircraft controlled by two co-pilot.
Since then, the stall alarm sounded twice, the aircraft speed instability. Once the pilot pulled the plane to 38,000 feet (about 11,600 meters) in height. The captain turned off the autopilot 1 minute 30 seconds to return the cab, but it was all recorded instrument failure rate, the stall alarm is stopped. Finally, the flight data recorder fixed in at 2:14:28 on on June 1st. Finally, the data show that head elevation was 16.2 degrees, 5.3 degrees left-leaning body to 10,912 feet per minute (about 3326 m) the rate of fall.
Investigation of the French Civil Aviation Safety Authority said the plane crashed lasted 3 minutes and 30 seconds, in the process, the aircraft is always in stall, but the engine has been run by pilots operating instructions. In layman's terms, the stall is generated when the aircraft lift is less than the aircraft weight, its altitude will be lowered, severe spiral to fall, resulting in the crash.
Investigation of the French Civil Aviation Safety Authority said the publication of this newsletter is designed to "black box" data recorded before and after the crash recovery to the initial situation. Preliminary investigation report will be published this year by the end of July, when the cause of the accident will include a preliminary analysis. According to French media reports, which result from the 216 passengers and 12 crew members killed in aviation accidents and aircraft may operate the speedometer and the pilot.
Earlier this month, investigators recovered one after another in the waters near Brazil crashed out of the two aviation aircraft flight recorder (the "black box"), and sent to the French analysis, but the guns on the plane has not yet been found.
