Why prohibit the use of electronic devices on airplanes?

In any country, when flying passengers are informed and

While flying passengers using personal electronics will produce electromagnetic radiation emitting electromagnetic waves of wide frequency. (Photo: talgov) is prohibited from using any electronic product on the aircraft. Why must to do that?

When the aircraft flies in the air, it is impossible to judge with the naked eye but rely entirely on electronic devices for her to control and control. Flight parameters such as altitude, plane direction, underground flight guidance system must also use radio power waves to command the aircraft to fly properly. If an electronic device has an error or indicates an effective underground route, it will threaten the flight safety of the aircraft, even an accident will occur.

The volume of electronic devices on modern aircraft is getting smaller, often working with low voltage and more sensitive to the electromagnetic wave system.If during the flight passengers use personal electronics such as mobile phones, electronic gaming machines, even electric razors, dryers, radios, . will also generate electrical radiation. The word emits electromagnetic waves with a wide frequency. There are many electronic devices on aircraft and navigation information devices that are within the frequency of electromagnetic waves. These electromagnetic waves will interfere, interfering in the normal electrical wave signals that flight needs, thereby making flight control ineffective, the consequences will be extremely serious.

Due to the need to use mobile phones anytime, anywhere; Recently scientists have built and used mobile phone tests on airplanes while flying.
