Electronic devices such as mobile phones can be left switched on during flights, the European Aviation Safety Agency (EASA) has announced.
The EASA says that electronic devices do not pose a safety risk.
The announcement clears the way for airlines to permit the use of mobile phones, once they have conducted their own safety reviews.
Currently airline passengers have to switch devices to flight mode and make calls from the airport terminal.
The EASA sets the framework for airlines making safety decisions.
The agency said each airline would still have to go through an assessment process, ensuring aircraft systems are not affected by the signals from portable electronic devices before establishing their own rules for their operation.
As a result there could be a delay in implementing the new rules at some airlines.
The EASA also says that airlines may opt for different policies on the use of mobile devices.
