The Malaysian investigation team set up an international working group, comprising agencies with expertise in satellite communications and aircraft performance, to take this work forward.
The international working group included representatives from the UK, namely Inmarsat, AAIB, and Rolls Royce; from China, namely the CAAC and AAID; from the US, namely the NTSB, FAA, and Boeing; as well as the relevant Malaysian authorities.
The group has been working to refine the Inmarsat data, and to analyse it together with other information, including radar data and aircraft performance assumptions to narrow the search area.
Information which had already been examined by the investigation was re-examined in light of new evidence drawn from the Inmarsat data analysis.
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.
