At present, more and more light and small drones have entered the lives of the people: electric commercial drones, people using drones to bring new year, and drone aerial photography... However, with the increase of “flying friendsâ€, The drones are also somewhat out of control. Comic: Disrupting Xinhua News Agency In recent years, drones have frequently broken into the “clean space†of airports around the country, causing delays in flights and posing a threat to civil aviation flight safety. The illegal flight of drones has been repeatedly banned. Is it really "unmanned"? Unmanned aerial vehicle "é—¯" airport On February 5, two UAVs broke into the airport clearance protection area at Kunming Changshui Airport. The drones flew directly into the runway area of ​​Changshui Airport. In the two days on the 2nd and 3rd, there were 4 illegal drone flights in Changshui Airport. According to the reporter's inspection data, in recent years, drones "breaking into" airports have affected the take-off and landing of flights, and have occurred many times in China. On February 3, Shenzhen Airport reported that three flight crews reported at the same time that unidentified lifts of suspected drones were found during the take-off or landing of the aircraft, threatening flight safety. The air traffic control department took emergency measures after receiving the report, and adjusted the interval between inbound and outbound flights to command air planes to avoid, resulting in different degrees of delay for multiple outbound flights. On February 2, Air China CA1918 flight crew found a light-emitting aircraft in the direction of Runway 32 of Mianyang Airport in Sichuan. After more than 2 hours of investigation and determination of the free space in the area, the airport resumed normal take-off and landing. On May 28 last year, a suspected UAV flying object appeared 17 kilometers away from the Longquan Lily Temple navigation station in Chengdu Shuangliu Airport, causing the Shuangliu Airport East Runway to be closed for 1 hour and 20 minutes... The reporter learned that the multi-destination airports have defined a clearance protection zone in the rectangular range of the airport runway extending 20 km to both ends and extending 10 km to both sides. However, as urban construction continues to expand, the scope of popular activities has become closer to the airport that was originally located in the suburbs. Zhang Wei, secretary-general of the Sichuan Provincial Navigation Association, said that there are more and more users of drones, and the phenomenon that “clean air†is difficult to clean is becoming more and more obvious. "Black Flying" threatens aviation safety The reporter's investigation found that China has already had clear laws and regulations on the drone industry. As early as 2013, the Civil Aviation Administration of China (hereinafter referred to as the Civil Aviation Administration) issued the Interim Provisions on the Administration of Pilots for Civil Aircraft Driving Aircraft Systems, which required to fly out of line of sight (distance over 500 meters or height over 120 meters) or A drone operator with an airborne weight greater than 7 kg is required to hold a “licenseâ€. The General Aviation Flight Approval and Management Regulations, implemented on December 1, 2013, clarify the approval and management of general aviation missions, including drones. In 2016, the CAAC Air Traffic Management Office issued the “Measures for Air Traffic Management of Civil Unmanned Aircraft Systemsâ€. Article 10 stipulates that civil unmanned aerial vehicles should be individually marked with isolated airspace, with clear horizontal range and vertical Range and time of use. Temporary airspace may be temporarily allocated for civil unmanned aerial vehicles in civil aviation airspace. However, in the densely populated areas, densely populated areas, key areas, and busy airport areas, in principle, civil unmanned aerial vehicles flying areas are not designated. Ke Yubao, Executive Secretary of the China Association of Aircraft Owners and Pilots (AOPA) and Director of the UAV Management Office, introduced that in December 2015, the Flight Standards Department of the Civil Aviation Administration issued the “Light and Small UAV Operation Regulations (Trial)â€. The drone was first classified in the same way. According to the regulations, the driver of the drone must obtain the airworthiness permit, and the flight is required to meet the requirements in terms of obtaining the license, certificate, grade, training, etc., otherwise it is illegal to operate, and the “black fly†will be punished. In addition, the Civil Aviation Law of the People's Republic of China stipulates that civil aircraft operating in controlled airspace should obtain permission from the air traffic control unit. Otherwise, the civil aviation authority will order to stop the flight, impose a fine on the owner or charterer of the civil aircraft; and impose a corresponding penalty on the captain of the civil aircraft. So, what are the serious impacts of drones entering the airport on flight safety? Xie Xiaoxia, head of Chengdu Zirui Qingyun Aviation Aerospace Co., Ltd., who is engaged in the research of low-altitude defense system, said that the passenger airliner is extremely fast during the take-off and landing process, and colliding with any object will have serious consequences. Nowadays, the UAVs used by ordinary people are mostly consumer-grade products. The flying height is low, the volume is small, and the flying speed is slow. The radar on the passenger airliner is hard to find, and it is difficult to avoid. At the same time, the aircraft's avionics equipment may be interfered by the drone signal, which is harmful to flight safety. “Setting up the airport clearance area is to ensure the safety of passenger and cargo aircraft during the take-off and landing process.†Ke Yubao said that any flying object must be approved by the airport authorities before entering the airport. "If the drone enters the airport clearance protection zone, then the passenger and cargo aircraft will avoid the drone, because the drone can not avoid the aircraft." Expert: Linkage supervision to ensure the safety of aircraft taking off and landing Ke Yubao introduced that at present, with the approval of the Flight Standards Department of the Civil Aviation Administration, the UAV cloud system “Yuyun†has been launched. The system is a dynamic database system for light and small civil drones. It is used to provide navigation services and meteorological services to drone users, and to monitor the operation data of civil drones in real time. In Ke Yubao's view, the supervision of drones is the same as the principle of car supervision. “Youyun system is currently only the stage of (the drone user) actively joining, and should be forced to join later.†In addition to supervision, Ke Yubao believes that users of drones should know more about aviation laws and regulations. Zhang Wei also told reporters that drone enthusiasts should strengthen their awareness of safety common sense and deeply understand the possible harm caused by illegal flight of drones. Xie Xiaoxia believes that UAV supervision should also limit producers, and should also enhance the safety of GPS flight control systems to prevent criminals from cracking the GPS flight control system, and the implementation rules of relevant regulations should be more detailed. Zhang Wei said that Sichuan Province is formulating the regulations for the real-name registration of drones and multi-department linkage supervision, and standardizing the management of drone flights. Many experts also pointed out that for areas such as airports that have high demand for clearance, an active defense system should be set up to fundamentally prevent illegal intrusion of drones.
