Signals have been detected from the black boxes of the AirAsia jetliner which crashed in the Java Sea, Indonesian military commander General Moeldoko said Friday.
"The location was estimated 300 metres from the initial point," Xinhua reported citing Moeldoko as saying in a media report.
The tail of the Airbus A320-200, which crashed in the sea off Indonesia's Central Kalimantan coast, was found Wednesday.
Moeldoko was onboard the navy's Banda Aceh, used as a baseship to supervise the operation to lift up the tail, which he said, was submerged in the seabed mud.
Seven divers were deployed to check the signals and confirm the position of the black boxes, Moeldoko added.
Flight QZ8501 went down Dec 28 en route from Indonesia's second largest city of Surabaya to Singapore with 162 people aboard. So far, 47 bodies have been recovered in a multinational search operation.
