The Chinese maritime search and rescue force has sent a rescue vessel to help search for the black boxes of crashed AirAsia flight 8501.
The rescue vessel, Nanhaijiu 101, meaning 'South Sea Rescue', is expected to reach crash area in the Java Sea off Indonesia within four days.
The Chinese vessel has echo-sounding apparatus and other necessary submersible devices for the search operation.
Aviation experts and rescue personnel are also on the vessel.
Yin Jie is with the China Maritime Search and Rescue Center.
"The experts will mainly take charge of data analysis, providing rescue guidance, intellectual support and decision reference."
In the meantime, Nanhaijiu 115 is also standing by near Yongxing Island in the South China Sea to join the search and rescue work, if needed.
AirAsia flight 8501 went down during bad weather soon after taking off from Surabaya in Indonesia's East Java en route to Singapore with 162 people on board.
37 bodies have so far been recovered.
