Safety Modeling And Simulation Of Parallel Runway Isolated Operation

With the continuous growth of air traffic flow,some airports at home and abroad began to build close parallel runway(CSPR)to meet the capacity requirements of civil aviation.Wake is a key factor affecting the operation mode of close parallel runways.In order to increase the take-off and landing capacity of the airport safely and prudently,it is necessary to establish a wake safety model and optimize the launch time.Firstly,through the statistical analysis of QAR data of typical models.To realize the simulation calculation of the trajectory of the take-off and departure and approach aircraft,the acceleration change and estimation model based on the take-off performance parameters,the take-off and departure trajectory calculation model,the approach trajectory calculation model,etc.,are established.Then,according to the current wake interval standard and the comparative analysis of the minimum runway required in the isolated operation mode of parallel runway,the wake safety calculation model of the isolated operation mode of close parallel runway was established.At the same time,the main factors affecting wake safety are calculated and analyzed.The research shows that the safety model of isolated parallel operation can effectively reduce the wake interval for the combined operation of different aircraft types.Under the given experimental conditions,the operation efficiency of air traffic control can be further improved on the premise of ensuring safety through the accurate calculation and control of the timing of take-off permit issuance.
