BERLIN (AP) ― European skies may soon be alive with the sound of small talk with new safety guidance allowing the use of all portable electronics, including cellphones, at any time during flights.

Under the guidelines issued Friday by the Cologne-based European Aviation Safety Agency, European airlines can, at their own discretion, allow passengers to leave electronics on during the entire flight, without the putting them into “airplane mode.”

“We’re basically opening the door where, in theory, you’ll be able to continue making your phone call through the gate throughout the flight ... like you would on a train,” spokesman Ilias Maragakis told the Associated Press.

Standing in the way is the difficulty of getting a cellphone signal at high altitudes, and also how passengers will react to the thought of sitting next to a chatterbox across the Atlantic.

That’ll be up to the airlines to figure out as they implement the new regulations. In most European trains, for example, there are “silent” cars where talking on phones is prohibited but it seems unlikely a scheme like that would work on anything but the largest jets.

In addition to phones, the guidelines apply to all other portable electronics, including book readers, tablet computers, mp3 players and other devices.

EASA said airlines sill now need to decide what devices they will allow and how they will allow them to be used. EASA also cautioned that even within airlines, the devices allowed could depend upon the aircraft type.

Airlines will also have to certify that their planes aren’t affected by transmission signals before they allow devices to be used.
