You can t use your mobile phone on the plane, otherwise there will be any harm

Introduction: Why can't I use my phone on a plane? I believe many people have this question, the following is a collection of information about why you can't use mobile phones on the plane, interested friends can take a look. <>

1. History** is on the plane, you can't swipe Weibo, chat WeChat, and watch**, this is something that most people know. The use of mobile phones is not allowed on board the aircraft because the signal emitted by the mobile phone can interfere with the pilot's communication equipment and navigation equipment. This can indirectly lead to the failure of aircraft navigation, or the interruption of air communications.

The inability to use mobile phones on airplanes originated many years ago because of the airplane communication system of that era.

It is very backward and easy to be interfered with, so in the era when mobile phones first appeared, mobile phones, which can transmit signal devices, were forbidden to be used in mobile phones, and this law has continued until now. <>

Second, the reason is as follows: the use of aircraft in flight will interfere with aircraft communication and navigation is a threat to flight safety killer, the aircraft throughout the flight, the use of wireless navigation equipment and ground navigation station to maintain real-time contact, control the flight route, in visibility.

In low cases, the instrument landing system needs to be activated for landing, that is, blind landing on the runway.

The station emits electromagnetic waves at the aircraft.

signal, in order to determine the runway location, and the mobile phone not only in the process of dialing or answering ** will emit electromagnetic wave signals, although each time the signal time is relatively short, but it has a strong continuity, so the mobile phone emits electromagnetic waves will cause interference to the aircraft navigation system. Compared with the impact of the aircraft communication system, the impact on the use of mobile phones on the aircraft is indeed obvious. When passengers use mobile phones on the plane, due to the fast flight speed, the region will also be switched frequently, which will increase the workload of the base station.

3. Prohibited itemsFlammable and explosive materials are prohibited on the aircraft.

It is forbidden to bring food such as jackfruit.

Honey, seafood, etc., if necessary, you can check in, it is forbidden to bring cosmetics and skin care products, and it is forbidden to carry handicrafts.

It may affect the magnetic field, so that the route of the aircraft will change to a certain extent, so that it may fly to other places and have some collisions, which will affect the safety of people's lives and property, and will also affect the connection between the tower and the aircraft.

It may affect the navigation of the aircraft and may even affect the radio communication on the aircraft. There is also the possibility of affecting electromagnetic waves and affecting signals. It will also affect communication and autonomous driving, and even affect the corresponding operating frequency.

Cause some radio wave interference.

The harm that will be caused is that it may affect the radar signal of the aircraft, and in the future, it will cause interference in the radar of the aircraft, and it will also affect the flight process of the aircraft, and it may also cause airflow fluctuations, and may also cause the turbulence of the aircraft. These are all hazards.

It will affect the navigation system of the aircraft, and it will also affect the signal of the aircraft, and it is easy to have radio wave effects on the system of the aircraft, unable to fly normally, unclear flight path, and so on.

First of all, the mobile phone will have a certain amount of radio waves and magnetic fields, which will affect the normal flight of the aircraft, and will also cause a certain amount of chaos, which will have a serious impact on the normal flight.

It doesn't matter how it is in China, and if it is abroad, it should not be necessary to shut down.

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 punished by public security administration and even criminal penalties. The use of mobile phones and other communication devices is prohibited on board the aircraft.

The flight community insists that it is very dangerous to use a mobile phone during a flight. All indications clearly prove this. "Although there is no conclusive evidence, it does appear that mobile phones can affect airplanes in certain situations.

So says researcher John Sheehan. Of course, such interference is rare. ”

What's even more ironic is that the cause of the mobile phone interference is still unknown. One explanation sounds plausible: the frequency of the moving ** is different from the frequency of the aircraft installation, so it causes interference.

There may be some repercussions to using your phone on an airplane. While there is currently controversy about the impact of mobile phones on flight safety, here are some possible considerations for the use of mobile phones on board aircraft:

1.Mobile phones cannot be used during take-off and landing, so as not to affect flight safety.

2.During the flight, the mobile phone needs to be set to airplane mode to prevent electronic devices from interfering with the normal operation of the aircraft.

3.When using your phone, you need to be careful not to put it in your pocket to avoid accidentally dropping it during the flight.

4.Mobile phones cannot be used on the plane for unsafe activities such as playing games, sending text messages, etc.

It should be noted that it is still not recommended to use mobile phones in extreme weather conditions, such as thunder and lightning, so as not to affect flight safety.

When you are in turmoil on a plane, you can take a state file to play with your mobile phone, but there is no way to use your mobile phone normally. Although the mobile phone can be turned on during the flight process, it is generally required to set the mobile phone to the flight mode.

Recently, YTO and other courier companies have been banned from carrying out air transport rights due to the transportation of mobile phone batteries in air cargo. The news is in a uproar, but do you know why airplanes can't carry lithium batteries? Doesn't the passenger's mobile phone on the plane also have a battery?

In this regard, the official explanation is often: lithium is a reactive metal, and it is easy to be squeezed. But why are electronic devices such as mobile phones and laptop batteries, which do not contain lithium metal, also one of the dangerous counter-goods prohibited by air?

As a chemistry graduate, we explain this simply from a professional point of view. First of all, we should understand the difference between lithium-ion batteries and lithium metal batteries: the positive electrode of lithium metal batteries is metal lithium, and after the metal lithium oxidizes during operation, electrons form an electric current through the circuit.

Lithium metal batteries contain lithium metal, so they are dangerous goods. The cathode material of lithium-ion batteries is lithiate, the anode material is a stove preparation graphite that can hold lithium ions, and the electrolyte is a salt called lithium hexafluorophosphate. When charging, under the action of the electric field, lithium ions flow from the positive electrode to the negative electrode, and when discharged, lithium ions flow from the negative electrode to the positive electrode, which is a reversible charge-discharge process.

Between the positive and negative electrodes of lithium-ion batteries is a polymer film that can only pass through metal lithium ions, and the strength of this polymer film is very low. In air transport, the aircraft is easily turned upside down due to the influence of air currents. A strong mutual collision between the bags can damage this film, causing a short circuit in the battery, causing a large amount of heat in a short period of time, causing combustion or **, damaging the aircraft, and causing a major accident.

The rechargeable batteries in electronic devices are now lithium-ion batteries. In order to avoid accidents and protect the safety of passengers' lives and property, it is forbidden to check in mobile phones or laptops and computers and other electronic devices in air transportation (including large cargo).

Nowadays, many mobile phones support airplane mode, and will not send or receive signals in airplane mode, which is the equivalent of PDA for mobile phones, in this case it is no problem to turn on the mobile phone. However, the general crew will still remind you to turn it off.

However, it is very dangerous to make ** or send receiving text messages on the plane, especially when the plane is taking off and landing. It should be absolutely prohibited, and I think it should be punished. Spitting on the road and fines, this is a matter of human life.

And the mobile phone in the normal standby state also continues to send and receive signals, it is also very dangerous The biggest problem with the mobile phone on the plane is that it may interfere with the navigation equipment, the aircraft can fly smoothly to the destination by the signals sent by the various navigation stations on the route to navigate, the problem of the mobile phone is that it may interfere with these signals, among which the interference in the landing and landing stage is the most likely and relatively the most dangerous. It's not just that just turning on your phone will interfere with the flight, it's a matter of chance, but it's a matter of safety, even if the odds are small, it's better not to use it.

No, because on the aircraft, these electronic devices in use will interfere with the aircraft's communication, navigation, and control systems, 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 aircraft destruction and death, and 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 the plane, you might as well ask yourself if you have turned off your mobile phone, pager, and game console, and hope to adopt thank you!

You can play it, but it's best not to play it when you just take off and land, it will affect the communication of the aircraft.

You can play with your mobile phone, but it is not recommended to do so, after turning on, there is signal and radiation, which may affect the work of the sensitive components of the aircraft, which may cause hidden dangers.

You can't play with your phone on the plane! Because the airflow will be affected, and the aircraft will be turbulent! You'll know if you've sat down.

It can be used, but it must be adjusted to flight mode, otherwise there will be electromagnetic interference, which will affect the navigation of the aircraft.

No, it interferes with the radar receiving signal, and the plane reads a book.
