Why can t you use your phone on a plane 10

1. Reasons why you can't use your mobile phone:

Radio waves from mobile phones may also cause** or affect the navigation system of an airliner flying at an altitude of 9,500 meters.

1. Scientific evidence also shows that the use of mobile phones on board is indeed potentially dangerous. If the frequency of the electrical appliance is more different from that of some aircraft, the interference caused will be minimized or completely undisturbed. In addition to the strength of the electrical signals transmitted by mobile phones, computers, radios, etc., which affect the aircraft, if the frequency they transmit happens to be the same or similar to the frequency of the aircraft, plus the amplitude (or amplitude), it will cause the greatest damage and a dangerous situation.

2. On the plane, the mobile phone in use will interfere with the communication, navigation and control system of the aircraft, which is a threat to flight safety"Killers"。Throughout the flight, the flight has used the on-board radio navigation equipment to maintain real-time contact with the ground navigation station and control the flight path. In the case of low visibility, the instrument landing system needs to be used for landing, that is, the blind landing platform on the runway is used to send electromagnetic signals to the aircraft to determine the runway position.

The mobile phone not only emits electromagnetic signals during the call or reception, but also constantly contacts the ground base station in the standby state. In its search process, although the time for each transmission signal is short, there is a strong continuity. Therefore, the electromagnetic waves emitted by the mobile phone will cause interference to the navigation system of the aircraft.

2. Not being able to use mobile phones on airplanes has become a thing of the past:

The dream of using a mobile phone on an airplane has come true since then. On a British Virgin Atlantic flight from Shanghai to London, passengers became the first guests to be allowed to use their mobile phones to make calls during the flight, a first for a global airline.

This latest in-flight service technology is equipped with BT's in-flight mobile communications system, which allows passengers to freely make mobile phone calls on board the aircraft, and the cost of the service will be automatically transferred to the user's Global Mobile phone account. Passengers only need to place their SIM card on the mobile phone provided on board the aircraft, enter their registration number, and communicate freely.

08/14 People's Daily Online-Jiangnan Times: The "level" of the competition between the two major operators of China Mobile and China Unicom has risen higher and higher, and it has been killed from the ground to the sky! China Unicom took the lead in revealing that it will soon launch a commercial in-flight CDMA wireless ** service, and the inability to call mobile phones on the plane will become a thing of the past.

According to the relevant person in charge of Unicom, to achieve the purpose of using mobile phones on the plane, as long as a built-in CDMA base station is installed on the aircraft, the base station can use communication satellites to achieve contact with the ground, and then access to the global land CDMA network. Once the device is in place, passengers can freely use their mobile phones to make calls or send text messages during the flight.

Why can't mobile phones and other electronic devices be used in the cabin?

On the aircraft, these electronic devices in use will interfere with the communication, navigation, and control systems of the aircraft, and will interfere with the wireless signal connection between the aircraft and the ground, especially when the aircraft takes off and descends, and the interference is greater, even if it only causes a small angle of course deviation, it may also lead to the consequences of the aircraft being destroyed and killed, and it is a "killer" that threatens flight safety. Take mobile ** as an example: mobile ** will not only emit electromagnetic wave signals in the process of dialing or answering, but also constantly contact the ground base station in the waiting state, although the time of each signal transmission is very short, but it has a strong continuity.

When the aircraft flies smoothly, 6000 meters to 12000 meters from the ground, at this time the mobile phone can not receive the signal at all, can not be used, in the process of take-off and landing, the mobile phone is possible to get in touch with the ground base station, but at this time the consequences of interfering with the navigation system are the most serious. Article 88 of the Civil Aviation Law of the People's Republic of China restricts the use of portable electronic devices by passengers on board, and Article 200 stipulates that violators shall be subject to public security administrative penalties and even criminal penalties. Airlines have also included a requirement for passengers to turn off portable electronic devices carried on board, including mobile phones, pagers, game console remote controls, amateur radio receivers, laptops, CD players, etc., which are prohibited from being used on board.

When we enjoy the convenience brought by modern technology, don't ignore the relevant laws and regulations of the country, especially when it comes to the safety of our own lives and the lives of others. When you step on a plane, ask yourself if you have turned off your mobile phones, pagers, and game consoles.

1 is interference 2 is that you can't get through with Ben When flying at an altitude of 10,000 meters and a speed of 850 kilometers, which mobile company can do it.

Because the electromagnetic radiation generated by mobile phones can seriously interfere with some of the aircraft's instruments and communication signals.
