SYDNEY (AP) -- Australia, Indonesia and Malaysia will lead a trial to enhance the tracking of aircraft over remote oceans, allowing planes to be more easily found should they vanish like Malaysia Airlines Flight 370, Australia's transport minister said Sunday.
The announcement comes one week ahead of the anniversary of the disappearance of Flight 370, which vanished last year on a flight from Kuala Lumpur to Beijing with 239 people on board. No trace of the plane has been found.
Airservices Australia, a government-owned agency that manages the country's airspace, will work with its Malaysian and Indonesian counterparts to test the new method, which would enable planes to be tracked every 15 minutes, rather than the previous rate of 30 to 40 minutes, Australian Transport Minister Warren Truss said. The tracking would increase to 5 minutes or less if there is a deviation in the plane's movements.
The trial is expected to use satellite-based positioning technology already on board 90 percent of long-haul aircraft that transmits the plane's current position and its next two planned positions, said Airservices Australia chairman Angus Houston, who helped lead the search for Flight 370.
The trial would boost the frequency in which planes would automatically report their position, allowing air traffic controllers to better track them, Houston said.
"This is not a silver bullet," Houston told reporters in the nation's capital, Canberra. "But it is an important step in delivering immediate improvements to the way we currently track aircraft while more comprehensive solutions are developed."
There is no requirement for real-time tracking of commercial aircraft and ever since Flight 370 disappeared, air safety regulators and airlines have been trying to agree on how extensively planes should be tracked. The Boeing 777 veered sharply off-course and vanished from radar shortly into its flight on March 8.
An international team of experts who analyzed a series of hourly transmissions between the plane and a satellite later determined that the plane traveled for another seven hours before crashing somewhere within a remote 60,000 square kilometer (23,000 square mile) patch of the Indian Ocean. An extensive, monthslong search of that area is still underway, but nothing has yet been found.
Houston warned that new method being trialed would not necessarily have allowed air traffic controllers to monitor Flight 370 -- whose transponder and other tracking equipment shut down during the flight -- to the point where it crashed.
"I think we've got to be very, very careful because you can turn this system off," he said. "What would have happened while the system is operating, we'd know exactly where the aircraft was. If somebody had turned the system off, we're in the same set of circumstances as we've experienced on the latter part of the flight of MH370."
