At the beginning of this month, the Civil Aviation Administration of China announced the revised draft of the “Civil Aviation Law of the People’s Republic of Chinaâ€, which clarified 14 kinds of illegal interference in the safety and order of civil aviation of micro-computers. One of them was “Using Mobile Phones in Aircraftâ€. If the special provisions are serious, the amount of fines may be increased to less than 50,000 yuan. For a time, the controversy over whether or not to use the mobile phone while on the plane and whether the mobile phone interfered with the plane signal was again raised. Today, let's talk about whether it is worth a fine of 50,000 on a plane to use a mobile phone. You can't use your mobile phone if you accidentally fined 50,000 airplanes? New Amendments to the Consultation Draft Speaking of this revision of the consultation draft, some of my friends may not know much about it. Here, the author will simply list some of the behaviors that are explicitly prohibited in this revision: Use of mobile phones and smoking in aircraft; Seize the seats and check-in counters; Hijack aircraft in flight or on the ground; Take hostages on aircraft or in airports; Forcibly break into aircraft, airport or aviation facilities, crash aircraft cockpit, and forcibly intercept aircraft; Illegally bring weapons, dangerous devices or materials into aircraft, airports or air traffic control units; Lies in dangerous situations, creates confusion, and disseminates false information such as those that endanger the safety of passengers, aircrew, ground personnel, or the public in aircraft or in airports, on airports, or in civil aviation facilities; Theft, deliberate destruction, unauthorized removal of aircraft equipment and other aviation facilities within the airport, forced opening of in-flight aircraft emergency response doors. Where does the mobile phone ban come from? It can be seen that apart from the controversy over the use of mobile phones in aircraft, any other one is a very clear and dangerous act. However, if a friend who has recently taken an international leg should understand that the use of mobile phones (including flight mode) will not be banned on flights to the United States, Singapore, Australia, and other countries. Then, what are the reasons for the obvious differences between domestic and foreign aviation industries? This matter will also be traced back to the 1990s. In 1991, the U.S. Federal Communications Commission thought that the impact of the use of mobile phones on aircraft was greater than that of mobile phones on the ground. Signals on mobile phones used by mobile phones were received by many base stations on the ground, causing interference to terrestrial networks and clearly banned on mobile phones. Claim. As an industry rule maker, other countries (including China) followed this approach after the United States. In fact, before the popularity of mobile phones, electronic products such as hearing aids and electronic dictionaries were also banned, mainly because the Federal Aviation Administration of the United States discovered that frequency-modulated wireless receivers could interfere with the navigation system of the aircraft. However, the regulations of the technology industry are always amended with advances in science and technology. Follow-up studies conducted by the Federal Aviation Administration show that most commercial flights can withstand radio interference from portable electronic devices. So on October 31, 2013, the United States The Federal Aviation Administration officially issued a cancellation of the use of mobile phone bans. At the end of November of the same year, the European Aviation Safety Agency issued guidelines to allow passengers to use portable electronic devices during taxiing, takeoff and landing. However, in China, new regulations have not yet been promulgated on the basis of considerations of security, system, and habits. New domestic regulations are long way to go The domestic civil aviation "Cabinet Service and Safety" clause stipulates that no portable electronic equipment, such as a mobile phone, that actively transmits radio signal functions, shall be turned on and used from the moment the aircraft closes the door to the time it takes to complete the opening of the door. This means that passengers need to turn off their mobile phones during takeoffs, landings and level flights, and include mobile phones with flight modes. After all, being open on the plane made mobile phones, airlines and passengers worry about security issues. The prohibition of the opening of mobile phones on domestic flights and even the use of flight modes are not allowed. This is not only a distrust of people's consciousness, but also a question of the uneven quality of different brands of mobile phones. Finally, it is simply one-size-fits-all. Here we must explain that since the radio used by mobile phones belongs to the same band as the radio used by the aircraft, it is possible to generate harmonic interference; in other words, the mobile phone signal will interfere with the VHF and affect the navigation system. VHF is the frequency band used by the aeronautical radio navigation system. This frequency band is easily affected by environmental factors such as terrain. Once the signal is affected, it will cause deviations in the navigation system and affect flight safety. However, so far, there have been no cases where the use of mobile phones caused aircraft communications and navigation interference. Even if the previous aviation accident was suspected to have been caused by a cell phone signal, it has not yet been confirmed. A better future after lifting the ban Therefore, through foreign regulations and experiences that have been opened up, do we also need to support the use of mobile phones on domestic airlines? Of course, before the state issued a clear directive, it is believed that no airline dares to eat crabs first. However, it is still too early to discuss this issue. We might imagine that if we really allow the use of mobile phones on airplanes, what can we do after we even turn on the flight mode? The author's first thought was definitely taking photos. When flying, usually prefer to choose the location of the window, watch the rare scenery in the life above the clouds. However, it has not dared to start taking pictures on domestic routes. If the ban is lifted, it will be a good time to have a lot of photos in the circle of friends. Sunrise in the sky before taking United on United Airlines On the other hand, after the mobile phone is allowed to use, the domestic airline can build a WiFi internet platform. For the user, it is possible to troubleshoot the boring time on the machine; for the airlines, what is an objective increase in revenue? Of course, building WiFi on the aircraft is also facing problems such as high renovation costs, unaffordable charges, and poor experience. When it is implemented, it needs to be carefully evaluated. There are already hints about WiFi on the back of the domestic flight Written at the end: "Safety" is the first consideration of aircraft. I believe this is undoubtedly true, but if we can guarantee safety, we will have more human experience and believe that it is beneficial to both consumers and practitioners.
