Recently, unmanned aerial vehicles have become the “black hands” that frequently break into the clearance area and threaten the safety of airline flight. A large number of flights have been delayed and many passengers have been stranded at the airport, causing widespread public concern.
Not only in Chengdu Shuangliu International Airport in the center of public opinion vortex, but also in many airports across the country, unmanned aerial vehicles have interfered with flights. Data show that in 2015, there were 4 illegal unmanned aerial vehicle interference incidents across the country, and in 2016, it increased to 23. Since April 14, 2017, unmanned aerial vehicles in southwest China have suffered “black flight”. As of May 2, there have been 9 public reports.
Is it because the regulations are not perfect? Ya-Nan Wang, member of the science popularization Committee of China Aviation Association and deputy editor-in-chief of Aviation Knowledge magazine, does not agree with this statement,”
The regulations have been relatively perfect, and there is no loophole to be drilled.”
As early as 2009, China issued “Interim Provisions on issues related to the management of civil unmanned aerial vehicles” and “measures for the management of civil unmanned aerial vehicle air traffic”. In 2012, the minutes of civil unmanned aerial vehicle airworthiness management meeting was issued, the Interim Provisions on the management of civil unmanned aerial vehicle system drivers were issued in 2013, and the operation of light and small unmanned aerial vehicles (trial) was issued in 2015. Regulations, etc.
In addition, China has also formulated the “civil unmanned aerial vehicle air traffic management measures”. The measures clearly pointed out that units and individuals who organized and implemented civil UAV activities should apply for the establishment and use of airspace in accordance with the general aviation flight control regulations and other provisions, without the approval of the Civil Aviation regional administration, it is forbidden to engage in UAV flight activities in the flight airspace of civil transportation airports.
China’s civil airport regulations also have relevant provisions, which clearly prohibit the release of kites, Kongming lantern, unmanned aerial vehicles and other winged creatures in the clearance area. Once the violators are captured, they will be fined more than 20000 yuan and less than 100000 yuan. If the released aircraft affects flight safety or causes a major safety accident, the maximum sentence can be sentenced to death.
“Compared with the above regulations, unmanned aerial vehicles are a latecomer, which only makes the standard objects concrete.” Ya-Nan Wang said.
Rules and punishment regulations are available, but the proportion of unmanned aerial vehicles “Black Flying” is still high. Can the ban and limit flying instructions be enforced through technical means?
In the global consumer UAV market, Shenzhen Dajiang Innovation Technology Co., Ltd. has a product share of 70%. Wang Fan, the head of the innovation public relations team of Dajiang, said that in addition to adding advanced technologies such as self-return and automatic obstacle avoidance to the products to ensure their own safety, Dajiang Innovation has been in accordance with the relevant regulations of the International Civil Aviation Organization, upgraded the airport polygon no-fly zone and limited-fly zone. For example, the aircraft cannot take off in the no-fly zone. When approaching the boundary of the no-fly zone from the outside, it will automatically slow down and hover. If you enter the no-fly zone without GPS signals, the UAV will automatically land after obtaining GPS signals.
Dajiang Innovation will gradually add manned aircraft early warning system (ADS-B) to new products, especially high-performance aircraft. Some old products can also be equipped with this function through software and hardware upgrades.” Wang Fan explained that the unmanned aerial vehicle equipped with ADS-B receiving device would add a pair of “clairvoyages” to its the pilot “. The system provides early warning for approaching manned aircraft, and will constantly remind and warn the pilot. At the same time, it will automatically according to the relative distance of civil aircraft, information such as the heading and the current flight altitude of the UAV operated by the user evaluates risks. If it is found that unmanned aerial vehicles have the potential to threaten civil airliners, in our country, the system can even force them to drop their altitude or force them to land.
Wang Fan also said that agricultural machinery or professional unmanned aerial vehicles are large in size and have special application scenarios. Dajiang Innovation will require real-name purchase. For consumer-grade unmanned aerial vehicles, users are not required to purchase them in real-name system, but by binding mobile phone numbers to associate the serial number of unmanned aerial vehicles and the innovative account number of Dajiang, various flight restriction notifications and precautions are sent to users in a timely and accurate manner, when an abnormal situation occurs, contact the user quickly; When a falling unmanned aerial vehicle is found, contact the user. “From the perspective of user experience, this is a service method that they can accept step by step and is also a management method that conforms to the current relevant policies and regulations.”
In Ya-Nan Wang, the use of technical means and strengthening account management are all semi-active supervision methods, that is, to provide basis for post-event tracing. He believes that the main reason leading to the “black flight” of unmanned aerial vehicles is the lack of active supervision means, which is the most important. “For example, air blocking means, directional interference or destruction means are adopted.” However, the disadvantage of this approach is that it is difficult to verify the configuration and the cost is high. “It can only be equipped in key areas.”
At the same time, he stressed that due to the separation of unmanned aerial vehicles from people during flight, it was difficult for airport police to find the master of the aircraft, and the psychology of luck and novelty encouraged the behavior of “black flying”. In addition, there have been many cases caused by model aircraft and unmanned aerial vehicle “black flight” all over the country, but they are basically only fined or detained. Ya-Nan Wang believes that the nature of “Black Fly” is no less severe than other violent means, and strong legal norms can play a deterrent role.
Wang Fan also hopes to bind the willful wings of unmanned aerial vehicles with a combination of punches, which can not only protect and support the healthy and orderly development of unmanned aerial vehicles, a new technology industry, but also maintain airspace safety.
