According to local media reports, in the afternoon of April 21st, Chengdu Shuangliu International Airport suffered a total of 4 “black fly†drones, resulting in 58 flights to Xi’an, Chongqing, Guiyang, and Mianyang airports. The aircraft returned and over 10,000 passengers were stranded at the airport.
This is the fourth batch of flights due to the "dark flight" of drones in Chengdu Shuangliu Airport and the time for passengers to stay.
Behind this, people in the industry believe that the current "black flight" of drones is still a hard-to-find, hard-to-prevent, and difficult-to-respond behavior.
Dajiang said that basic exclusion is the product of their company.
The police disclosed on April 22 that it had captured one of the drones "black flying", but did not disclose what type of drone the person was using. The current case is under further investigation and has not yet been quantified.
A former witness told the reporter that the drone he saw in the vicinity was larger in size and more than one meter high, which was similar to the appearance of civilian airliners. According to a report by the Beijing Youth Daily, a person inside the Sichuan drone circle also witnessed a drone, which resembles a "fighter."
On April 21st, DJI, a domestic manufacturer of unmanned drones with a market share of 70%, told reporters that according to the investigation, suspected drones in the basic exclusion event were Dajiang products.
According to the relevant person in charge of DJI Innovation, according to the location and altitude information of suspected UAVs provided by the relevant departments and the investigation by Dajiang, the suspected flight areas were all located in the Chengdu Shuangliu Airport banned and restricted-fly zone built by DJI. The drones produced in Dajiang in the past three years were all equipped with a no-fly zone system. They could not take off and fly in the no-fly zone. The flight altitude in the restricted-fly zone was strictly limited and could not appear in the suspected position.
One drone enthusiast analyzed that this kind of drone should be a fixed-wing model, and some of them were assembled by some flying enthusiasts themselves to buy parts from the Internet. They may not have a specific brand and are difficult to trace.
Drone supervision mechanism needs to keep up
Since 2016, airports including Chengdu, Mianyang, Chongqing, Hangzhou, Shenzhen, Kunming, Harbin and other airports have experienced drones affecting the normal flight of flights.
Before the Civil Aviation Administration’s Flight Standards Division, a number of regulations and policies have been formulated, such as “unmanned drone air traffic management measures†and “light and small drone operation (for trial) regulations†for drones and unmanned aerial vehicles.
However, people in the industry believe that the current "black fly" is still a hard-to-find, hard-to-prevent, inconvenient behavior. UAVs are often small in size, and many of them are made of non-metallic materials such as plastics and fiberglass. Therefore, it is very difficult to detect and warn them. Once discovered, it takes a lot of manpower and material resources to verify. Applying for legal flight of drones requires a long time for approval and complicated procedures. Therefore, many enthusiasts prefer to “black fly†and are unwilling to apply. In addition, China has not yet established a real-name registration system for drones, regardless of whether or not drones have submitted applications for flight. Because of the lack of registration, it is difficult to pursue the accountability of the owner.
The relevant person in charge of DJI Innovation believes that the enforcement of the no-flying and fly-by-fighting instructions through technical means can actually make the drone "go its way" through intelligent means and reduce human-induced disturbances, so that the no-fly and flight-limit instructions are obtained. Strictly enforced. This will greatly reduce the possibility of drones threatening civilian aircraft.
Most of the UAV products on the market are equipped with satellite positioning modules such as GPS or BeiDou, and the drone can know its real-time location and height. Taking Dajiang’s drone products as an example, Dajiang has a satellite positioning module for each product. In addition, it has collected geographical coordinates of more than 6,800 major airports in the world, and pre-installed each of them. Man-machine products.
According to the above-mentioned industry insiders, although some drone manufacturers set up no-fly zones, there are individual businesses on the Internet that specialize in providing "crack" services for no-fly zones. Some of the professional equipment used to disperse drones, such as "electromagnetic guns", have been applied in some areas, but their cost is high, and it is difficult to obtain large-scale promotion at present.
