BBC News | Mobile phone use backed on planes Passengers could soon be using their mobile phones on planes flying through European airspace. Plans have been developed across EU countries to introduce technology which permits mobile calls without risk of interference with aircraft systems. Regulators around Europe are calling for consultation on the potential introduction of the technology. If given the go ahead, the service would allow calls to be made when a plane is more than 3,000 metres high. Individual airlines would need to decide if they wanted to introduce the technology, if the green light is given by national regulators.
