Plane banned mobile phone terminals | I am cheated these years?

All along, we all have a question: since the plane is not allowed to use the flight mode, then why is it called the flight mode? Like pearls in pearl milk tea, his wife had no wife cake, the flight mode has been "unworthy of the name."

However, on January 15, 2018, CAAC released Guidelines for the Evaluation of the Use of Portable Electronic Equipment (PEDs) on Boards, believing that the conditions for using PEDs in open machines have basically become mature. In other words, The phone can be used soon!

Excitement? There are still more than you excited, China Eastern Airlines and Hainan Airlines has announced the official opening of the PED from 18 on the use of which Eastern Airlines said since January 18 zero, passengers in the actual carrier flights can be used throughout the Flight mode.Huai said PED open first flight HU7781 Haikou to Beijing will be at 17:10 on the evening of 17 smooth takeoff, and personally by the president of Hainan Airlines fly, the two in order to fight the first fight The president personally opened the plane.

▍ Why banned the use of mobile phones on the plane? Why suddenly lifted it?

Then the question came, why can not we boot before? Why suddenly lifted it?

The issue has to start with the long history of the aircraft. As we all know, aircraft flying in the sky need to stay in touch with the ground, especially when taking off and landing. The medium used to keep in touch is the radio. Radio is divided into a variety of different frequencies, different uses of equipment will use different frequency bands, if two different uses of the equipment are using the same frequency band, it will inevitably produce radio interference.

It's like when we're driving on the highway, it's also divided into fast lanes, slow lanes, and emergency lanes. If the cars stay in their lane at their own pace, the road will be unobstructed, Road, it is bound to cause congestion.

As early as 1919, with the end of World War I, many countries converted military aircraft into civilian aircraft. Since then, aircraft have been using radios much earlier than the birth of mobile phones. Until the nineties of last century, mobile phones began to gradually come into our lives, appeared in the aircraft more and more times, which can not help but let many people worry, Will the frequency bands used by mobile phones affect the safety of the aircraft?

Indeed, up till now, there will be similar news that passengers are calling in the cabin and the aircraft signals are disturbed. However, after these experiments, It can not be precisely proved that the signal interference from the aircraft is caused by the mobile phone because the radio-capable equipment is too much and the reasons for the interference are very complicated. The aircraft is of no small importance. Although the aircraft may use the standby frequency band when disturbed, , But for flight safety, are banned.

With the passage of time, but also with the use of radio equipment more standardized, we gradually found, The phone does not affect the flight safety of the plane , So FAA (Federal Aviation Administration) a few years ago a large number of lifting the ban on the use of mobile phones.

Civil aviation agencies in our country have always adopted the most stringent standards for safety. In September 2017, the Civil Aviation Authority relaxed its regulations on in-flight portable electronic devices and allowed airlines to assess the impact of portable electronic devices. And to develop the corresponding management and use policy.And until January 15, 2018, CAAC issued the "Guide", the airlines began to follow up this guide.

▍ currently lifted the airlines have these, there are these provisions

Currently, the fastest announced lifting of the ban is the Eastern Airlines and Hainan Airlines, the two will be January 18, 2018 began lifting the ban on the 18th afternoon, China Southern Airlines microblogging also released news that from January 19, 2018 Day, take the actual carrier flight of China Southern Airlines passengers, the use of mobile phones in the flight process.As of press time, the four major domestic airlines have three lift the phone restrictions. Air China's customers are as follows ↓↓↓

Other airlines follow suit one after another, with Xiamen Airlines lifted on January 19 and all domestic and international flights to Spring Airlines will be banned on February 1. Shandong Airlines announced today that it will ban the ban on Jan. 22 Use the phone on the plane, from the day on the sailing flight, you can boot.

Attention! Not let you boot you can easily play! At present, all the lifting of the ban on mobile phone airlines are required to use the flight mode on the plane!! Do not have the function of the mobile phone and other devices in the air mode is still prohibited in the air.

It is noteworthy that the Guide states that during the flight, when the pilot-officer detects the presence of electronic interference and suspects that the interference comes from the portable electronic device used by the crew on board, the captain and the pilot-in-command have the right to request that they close the portable Electronic equipment. So if there's a staff member to shut you down, hurry up.

▍ What is the experience of using a cellphone on an airplane?

Since the recent lifting of the ban has just started, many users have never played on the phone before the plane, then play the phone on the plane what is the experience?

In fact, both foreign and domestic airlines require that the flight mode be activated at the time of take-off and landing and that only some foreign airlines allow the flight mode to be closed during the cruise phase. At this time, We have absolutely no way to connect to the ground station at a height of 10,000 meters. In short, there is no signal! There is no way to make phone calls and use data traffic.

With this in mind, many airlines now have onboard Wi-Fi services , The unified data transmission via satellite, and the satellite transmission speed can be completely less than the ground optical fiber, so there will be some delay, may brush microblogging and circle of friends okay, want to watch high-definition video online or forget It

利 aircraft lift the pros and cons of mobile phones

For many people, leaving a cell phone feel uncomfortable, each time on the plane as the world has evaporated, and after lifting the ban, although it can not call, but can also be quite good with Wi-Fi. To the family reported a safe, take a look at the video using a mobile phone to play games, shoot a porthole landscape is not bad.

From an industry perspective, the lifting of the ban on handsets by domestic airlines will certainly bring about a new round of on-board Wi-Fi development. When we later choose the flight, in addition to considering the time and comfort, it may also consider the airline's fast moving speed, there is no delay.

But there are also many users worry: From then on, you can often see the first class net red play live broadcast, the leader urging you to work on the ground, aunt watching the video without headphones, that time will miss the request that the phone off It's

Shut down Ye Hao, do not shut down worth mentioning, but also please follow the aircraft crew command arrangements. Flight safety and the cabin environment need to work together to maintain.
