Today the use of personal phone on board is restricted. Some airlines have begun to authorize its use during shipping and while the aircraft doors are open, but the moment they close, the phones must be turned off.
The reason is none other than the emissions of these can affect a range of aircraft navigation systems, resulting in security risks that entails, and which are already known and documented case studies, which have been a flight real danger.
telephones installed in airplane seats by the airlines themselves, or in some parts of it, for use by passengers, are prepared to not cause interference, and that is why they can be used to call them.
Can you use cell phones on the plane?
However, at present, several firms are developing systems to allow any passenger can call or receive calls while flying. Currently, phones on board should contact one of the repeater towers that mark the geography, and it must broadcast at full power.
In developing the new equipment, telephones emit through antenna located inside the plane, so the energy of these will be much lower. The external link is done using the same satellite technology that allows Internet and enjoy real-time onboard many airlines.
is curious, however, that the possibility of using the aircraft on board, is unevenly received by potential customers. Many people see it, the power to be communicated at all times, but many others, no. About the possibility of "disconnect" from work, at least in part, during the flight, and others consider to be annoying trying to rest and sound mobile phones on board, or simply that you mate pass seat the entire flight talking.
