In addition, international partners – who continue to process data in their home countries, as well as in the international working group – have further refined existing data. They have also come up with new technical information, for example on aircraft performance.
Yesterday, this process yielded new results, which indicated that MH370 flew at a higher speed than previously thought, which in turn means it used more fuel and could not travel as far. This information was passed to RCC Australia by the NTSB, to help further refine and narrow the search area.
The Australian authorities have indicated that they have shifted the search area approximately 1,100 kilometres to the north east. Because of ocean drift, this new search area could still be consistent with the potential objects identified by various satellite images over the past week.
This work is on-going, and we can expect further refinements. As the Australian authorities indicated this morning, this is standard practice in a search operation. It is a process of continually refining data which in turn further narrows the search area. With each step, we get closer to understanding MH370’s flight path.
Searches must be conducted on the best information available at the time. In the search for MH370, we have consistently followed the evidence, and acted on credible leads. Our search and rescue efforts have been directed by verified and corroborated information. This latest refinement of the search area is no different.
