Detection And Statistical Analysis Of Unsafe Events In Civil Aviation Aircraft

With the rapid development of Chinese economy, The number of aircraft is growing rapidly, resulting in a case of "Air traffic jam" occurs frequently, more and more "air traffic control delays reason" so that the air traffic control system suffered unprecedented pressure to China's airspace management and air traffic control units ushered in an unprecedented challenge. And limited natural resources, airspace and traffic management techniques and tools lag makes air traffic safety accidents, flight delays increased.From the impact of flight delays, the most important factor-air traffic control process under the constraint of the airspace structure as a starting point, from system level modeling and analysis of the entire air traffic network, airspace is divided into sectors based on operational efficiency and workload and dynamic routes such as the deployment of air traffic management foundation. Issue from the following aspects Expand:(1) The entire air traffic system level to proceed for an aircraft to air traffic continuous process and the specific configuration characteristics of different routes, aircraft modeling conducted to establish coordinates and equations of motion, and in accordance with the scope of the aircraft unsafe events selected interval collision model aircraft.(2) From horizontal and vertical directions and dangerously close to aircraft collision incident unsafe algorithm, and using a reasonable algorithm for detecting air traffic control system in the event of unsafe, Dalian airspace for small, complex route characteristics made Adjustment.(3) After the corresponding algorithm simulation statistics recorded incidents of insecurity, as well as records and route traffic statistics, the total amount of ATC calls and unsafe aircraft incident data and other simulation results, and the severity of the conflict through the evaluation model planning more optimized air traffic control system conflict prediction rules. Finally, based on simulation results obtained security report, in order to obtain a more optimal use of airspace management program.Simulation results verify the results of this study in the real production process, reaching the dangerous situation of the aircraft and prompt detection statistics of the expected results on the aviation security work has practical significance.
