From the 26 September 2014 EASA has made it possible for airlines to allow passengers to use their PEDs throughout the flight, regardless of whether the device is transmitting or not, i.e. in ‘aeroplane mode’ or not. Of course, it is up to each airline to allow the use of PEDs or not. In order to do this, airlines will have to go through an assessment process, ensuring aircraft are not affected in any way by the transmission of signals from the PEDs.
So, slope shoulders from the regulator, down to the airline.
