Search team Malaysia Airlines MH370 aircraft ready to deploy submarines to track the plane's black box , which seems to have run out of battery . In the search Sunday , attempts to detect signals below the sea by deploying ships and aircraft not produced results .
According to the Australian authorities on Monday , a search in the Indian Ocean has entered the sixth day since the ship Ocean Shield country's navy captures a series of pulse signals is consistent with the frequency of the black box . Air Chief Marshal Angus Houston , the leader of the search team , said the next step is the most plausible vehicle launches browser seabed area to continue the search ..
The vehicles will be used is the Bluefin - 21 , an unmanned submarine . The tool is expected to provide a visual confirmation of the existence of MH370 wreckage on the ocean floor . The discovery of the black boxes is very important because it can explain the cause of the plane melencengnya and these should disappear .
Loss of pulse signal from the plane's black box will be increasingly difficult for search . According to officials who led the search , the location of the hunt which is about 2,200 miles northwest of Perth , Australia , has an area of 1,300 square kilometers . Meanwhile, the Bluefin - 21 submarine capable only down an area of 30 square kilometers per day .
Bluefin - 21 can be programmed to perform a search mission in particular about 20 hours by using side sonar to look for certain things in the bottom of the sea . The new data can be analyzed after the submarine returned on the surface .
If the operator at Ocean Shield saw anomalies , sonar scanner facility Bluefin - 21 will be replaced with sophisticated underwater camera . However, these submarines can not carry sonar and underwater cameras simultaneously.
In a previous search , the search vessel named Ocean Shield to use tool U.S. Navy to capture the pulse signal from the black box . Australian military aircraft also record information from dozens of underwater sound detectors nicknamed " sonobuoy " that began to be placed in the water last week . Sonobuoy microphone can be stretched up to a depth of approximately 300 meters below sea level .WSJ
