It is not allowed during take-off and landing. But after the plane enters the stratosphere, you can play with your mobile phone. There is WIFI on the plane, and you can access the local area network of the plane, where there are movies to watch. There is also dating software that can chat with other people on the plane. It is almost common sense in China that mobile phones cannot be used on airplanes. But later, this "common sense" was broken At the press conference of the Civil Aviation Administration of China on September 18, Zhu Tao, deputy director of the Flight Standards Department of the Civil Aviation Administration of China, introduced that in the future, airlines can decide what kind of portable electronic equipment to use on their planes according to the evaluation results. Subsequently, Spring Airlines made the first statement: "It is optimistic that in the first half of next year, passengers are expected to be able to use mobile phones on the plane." In addition, according to the interview of Southern Metropolis Daily with the relevant person in charge of Air China, the release of portable electronic equipment on the plane involves many factors, such as the change of flight standards and related tests, so it will not be released in a short time. In August last year, the Civil Aviation Administration of China published the revised draft of the Civil Aviation Law of People's Republic of China (PRC), stipulating that it is strictly forbidden to use mobile phones or other prohibited electronic devices on airplanes, and offenders may be fined up to 50,000 yuan. In addition, whether you can use a mobile phone by plane has also caused several big discussions. The party who opposes the use of mobile phones thinks that it is related to flight safety and it is best to be safe. On the other hand, supporters argue that there is no clear evidence that using mobile phones affects flight safety. In fact, in foreign countries, it took a long time from banning portable electronic devices such as mobile phones from boarding to lifting the ban.
