The co-pilot of AirAsia Flight QZ8501 was flying the passenger jet when it crashed last month, officials have said.
It was last week reported that the plane was climbing at a speed "beyond normal" before stalling.
Recovery efforts are still underway following the crash, which left all 162 on board dead.
The flight data recorder retrieved from the wreckage of the crashed AirAsia plane arrived by helicopter at the search base in Indonesia today.
The recorder was transferred from salt water to a transparent container with fresh water upon arrival at the airport in Pangkalan Bun.
It will be handed over to the chief of the National Transportation Safety Committee before being transported to Jakarta for investigation.
