SYDNEY (AFP, REUTERS) - Missing Malaysia Airlines flight MH370 was “highly, highly likely” on autopilot when it ran out of fuel and crashed, Australian officials said on Thursday as they announced the search will shift further south.“It would be fair to comment that it is highly, highly likely that the aircraft was on autopilot, otherwise it could not have followed the orderly path that has been identified through the satellite sightings,” Deputy Prime Minister Warren Truss said.

The Boeing 777, carrying 239 passengers and crew, disappeared on March 8 shortly after taking off from Kuala Lumpur bound for Beijing.Investigators say what little evidence they have to work with suggests the aeroplane was deliberately diverted thousands of kilometres from its scheduled route before eventually plunging into the Indian Ocean.The search was narrowed in April after a series of acoustic pings thought to be from the plane’s black box recorders were heard along a final arc where analysis of satellite data put its last location.

But a month later, officials conceded the wreckage was not in that concentrated area, some 1,600 km off the northwest coast of Australia, and the search area would have to be expanded.

“The new priority area is still focused on the seventh arc, where the aircraft last communicated with satellite. We are now shifting our attention to an area further south along the arc,” Mr Truss said.He added that the new priority search area was determined after a review of satellite data and early radar information as the plane suddenly diverted across the Malaysian peninsular and headed south into one of the remotest areas of the planet. 

Two vessels, one Chinese and one from Dutch engineering company Fugro are currently mapping the seafloor along the arc, where depths exceed 5,000 metres in parts.The next phase of the search mission is expected to start in August and take a year, covering some 60,000 sq kilometres of ocean at a cost of A$60 million (S$70.4 million) or more. The search is already the most expensive in aviation history.
