Europe has announced new proposal to make it easier to find black boxes from missing planes.
The plans by aviation watchdog include extending the transmission time of underwater locating devices fitted on the black boxes from 30 to 90 days.
The move comes in response to the disappearance of flight MH370 on 8 March.
According to the BBC, the European Aviation Safety Agency (EASA) said, under the new plans, large planes flying over oceans should be equipped with a new pinger frequency, making it easier to locate the recording devices under water.
In addition, the minimum recording duration of cockpit voice recorders installed on new planes should be increased from two to 20 hours, the report added.
