Flight recordings from an Air France jet that crashed into the Atlantic Ocean in 2009 have been preserved and are readable, French investigators have said.
They said the material from the voice and data recorders, retrieved earlier this month off the Brazilian coast, will now be analysed.
The readings include the last two hours of the cockpit voice recordings.
All 228 people on board were killed in the disaster.
Any information gleaned from the cockpit voice and flight data recorders will take months to process, investigators have said.
The report into the cause of the crash itself will not be ready before early 2012, although an interim report is likely to be published mid-2011.
Flight AF 447 went down on June 1, 2009 after running into an intense high-altitude thunderstorm, four hours into a flight from Rio de Janeiro to Paris.
The wreckage of the plane was discovered after an extensive search of 10,000 sq km of sea floor.
