Why can you get on a plane with a mobile phone that can access the Internet 40

In the past, it was not possible to get on it, and the most critical problem was not to interfere with the flight, and the mobile phone did not have a signal after the plane was in the sky (the mobile phone signal used a ground base station). However, some aircraft are now equipped with PICO base stations, which are connected to the ground communication network through satellites, and will not affect the flight safety of the aircraft.

The signal transmission system used for wireless Internet access on the aircraft uses a channel dedicated to communication on the aircraft and does not interfere with the navigation system. The frequency band of the mobile phone has not been specifically selected and is likely to cause interference

On the plane, mobile phones can generally access the Internet, and airlines order passengers to turn off the plane after boarding, that is because the high-end system on the modern high-tech aircraft is very sophisticated, and the signal radiation of the mobile phone will interfere with the operation of the aircraft system and bring some unnecessary risks, so it is explicitly ordered to shut down.

The number of seats on various aircraft types is different, and the same aircraft is divided into several series, such as B737 (Boeing 737) B737-200, B737-300...There are many other series, such as the B737-900, and the number of seats in each series is different. There is also a model, the same series of models, different airlines, the number of seats will be different, because airlines in the purchase of aircraft, will be according to their own needs to require manufacturers to adopt different layouts, different layouts will have different first class, business class, economy class seats, because different classes of seat width, the distance between the front and rear is different, the same is economy class, the distance between the front and back of the seat will be different depending on the airline, the greater the distance, the more comfortable, However, the number of seats on the whole aircraft is less, so airlines will make different choices between comfort and economy.

The number of seats on common aircraft types is as follows:

1. Large wide-body aircraft: the number of seats is more than 200, and the aircraft has a dual-aisle passage 747 Boeing 747, and the number of passengers is about 350-400 E are different models of Boeing 747).

777 Boeing 777, carrying about 350 passengers. (or codenamed 77B) 767 Boeing 767, carrying about 280 passengers.

M11 McDonnell Douglas 11, carrying about 340 passengers.

340 Airbus 340, carrying about 350 passengers.

300 Airbus 300, carrying about 280 passengers (or ab6 as the code) 310 Airbus 310, carrying about 250 passengers.

ILW Il-86, Soviet aircraft, carrying about 300 passengers2, medium-sized aircraft: refers to a single-aisle aircraft, carrying more than 100 passengers, less than 200 peopleM82M90 McDonnell Douglas 82, McDonnell Douglas 90 carrying about 150 passengers733 Boeing 737 series carrying about 130-160 passengers320 Airbus 320, carrying about 180 passengers.

146 British Space Corporation BAE-146 aircraft, carrying 108 passengersYK2 Yak-42, Soviet aircraft, carrying about 110 passengers3, small aircraft: refers to aircraft with less than 100 seats, mostly used for regional flights YN7 Y-7, domestic aircraft, carrying about 50 passengers.

AN4 An-24, Soviet aircraft, carrying about 50 passengers.

SF3 Saab 100, carrying about 30 passengers.

ATR Yatai 72A, carrying about 70 passengers.

Some planes can, some can't.

As of 2021, the airlines that can use mobile phones to access the Internet on board are: China Eastern Airlines, Lucky Air, China Southern Airlines, Xiamen Airlines, Sichuan Airlines, Shanghai Airlines, Spring Airlines, Shandong Airlines, Loong Airlines, Shenzhen Airlines, Capital Airlines, and Air China.

Details to look out for on the plane:

1. In the key stages of taxiing, take-off, descent, and landing, it is forbidden to connect mobile phones to earphones, charging cables and other accessories, and computers are not allowed.

2. The wifi on the plane is not available to all passengers, first class and business class can be used, economy class is special, sometimes temporarily free, free when there is a time limit.

3. In the process of using the mobile phone on the plane, it is not possible to carry out voice ** and ruler Zheng Xin, so as not to interfere with the normal connection of the radio of the aircraft. <>

It's a good idea to set your phone to airplane mode on the plane, so that your phone signal won't affect the normal flight of the plane.

*Internet access is available on board**.

In recent years, in order to meet the needs of the majority of passengers, according to China's national conditions, after a series of work such as technical testing and regulatory revision, the Civil Aviation Administration of China believes that the conditions for opening up the use of portable electronic devices (PED) on board have basically matured.

The use of mobile communication equipment on the aircraft will generate electromagnetic waves, which will interfere with the navigation equipment and autopilot system of the aircraft, and endanger aviation safety. Therefore, to be sure, airlines will require the aircraft to be switched off or switched to Xiangqing airplane mode at all times.

It is important to note that there may be differences in the provision of WiFi services to passengers on different airlines and flights. Generally speaking, first and business class are free to use all the time, and economy class can be free for 10 minutes, and then you need to purchase and redeem points.

Although you can access the Internet on board, you need to comply with the airline's regulations and turn off or switch to airplane mode during the full flight to ensure aviation safety.

Internet access is available on the plane, but it must be turned off or turned on airplane mode before takeoff.

The use of mobile communication equipment on the aircraft will generate electromagnetic waves, which will interfere with the navigation equipment and autopilot system of the aircraft, and endanger aviation safety. Because the aircraft is in a low-altitude flight state during takeoff, climb, and landing, radio navigation and communication systems may be subject to any electromagnetic interference, which can cause serious consequences.

However, when the plane flies to a certain altitude and is in a stable state, the mobile electronic devices basically have no signal, and at this time, they can only take pictures and watch local movies, so there is no interference. However, for the sake of safety and to ensure that nothing goes wrong, airlines will still require the entire flight to be turned off or put into airplane mode.

Pay attention to the time period used:

After all, the plane is different from the ground, especially when the plane is about to take off and land, or when the conditions are not very good during the flight, it is recommended that everyone try to avoid using the Internet.

Although the network we connect to is not the usual mobile phone signal, it will also have a certain impact on the communication between the aircraft and the ground. In addition, in such a situation, the aircraft is generally relatively unstable, and if it is not used properly, it will also cause motion sickness and other phenomena.

Although there is no clear conclusion on whether the use of mobile phones on the plane will necessarily affect the aircraft, the mobile phone, as a wireless communication device, will emit electromagnetic wave signals and occupy a certain frequency in the process of dialing or answering, and the communication and navigation equipment of the aircraft also has its own special frequency and frequency band. Precautions for taking a plane: Recently, there have been frequent plane accidents, and everyone always thinks that the plane is unsafe, but in fact, the attention has increased, the frequency of accidents has not changed much, the spread of information is relatively fast, and everyone knows what is happening in the world.

But we have to be more aware of security.

Before you fly, it's a good idea to book a relatively safe spot. When it comes to escaping, the faster you can escape, the better your chances, so it's best to choose a seat close to the exit and aisle, and try to choose a position at the back of the plane.

Buckle up. It's common sense, but it's hard to get everyone's attention. Seat belts can protect themselves in the seat in the event of an accident and reduce the damage caused by inertia.

Read the safety card carefully and pay attention to the safety notices before you fly. Because only if you understand the safety door and other contents of the aircraft, can you be yourself in danger, and don't completely give yourself to others, because the crew may be injured in the event of danger, and you can only find a way to do it yourself.

Pay attention to the oxygen mask. Although the time provided by the oxygen mask is limited, it is important to wear the oxygen mask in case of emergency to avoid inhaling toxic gas or dust, which may cause suffocation.

Hold your horses. This is the most important thing, no matter what the accident, the mentality is the most important, only a calm mind will bring yourself out of danger smoothly and safely.

Yes, you can access the Internet, but you need to turn on airplane mode. Nowadays there are many planes that can be connected via satellite networks. Internet platform, but you still can't use ** answering and other functions, which may interfere with the aircraft's communication equipment, so it is best not to use mobile phones on the plane.

There is an internet connection on the plane, but you can't use a mobile phone, because the plane has to receive the signal from the signal tower while it is moving, and if you use a mobile phone, it will interfere with the signal of the signal tower and the aircraft.

The network signal will not be in the air, you can only see if the flight provides wifi signal through satellite, very few flights have this service, so basically you can't access the Internet!

There is no wifi on civil aircraft nowadays. The use of mobile phones in flight is also not permitted.

Airplane mode is required on the plane, so there is no signal on the mobile phone.

There is no mobile phone signal on the plane, and the general aircraft does not provide wifi at present
