Research On Capacity Simulation And Evaluation Of Multi Runway Airport In Pairing Operation Mode

With the rapid development of civil aviation industry,major airports at home and abroad are also facing the problems of capacity saturation,even supersaturation.In the limited land resources,it is an urgent strategy to increase the number of airport runways or to plan and build new airports.However,the high investment cost and long time limit make this method not the best choice.On the premise of ensuring safety,changing the operation mode of the runway can reduce the wake gap between the front and rear aircraft,so as to improve the runway capacity of the airport and increase the operation efficiency of the airport surface.In such a background,the matching operation mode for the short distance parallel runway is proposed.Pairing operation has not been implemented in China,so more theoretical support and simulation evaluation are needed to pave the way for pairing operation mode.So the main research contents of this paper are as follows.Firstly,in order to reduce the wake separation,the new RECAT wake separation standard is introduced,and the influence of the new wake separation standard and the current wake separation standard on the matching operation capacity is compared and analyzed.Combined with the actual matching operation,the capacity evaluation model under the influence of human factors and equipment factors is constructed.Secondly,on the basis of describing the taxiway system,taking the runway crossing into account the capacity model,this paper constructs the pairing capacity evaluation model under the condition of runway crossing,and compares the impact of runway crossing on capacity improvement under different pairing entry and departure combination modes.After the completion of the above two capacity evaluation models,a matching entry scheduling model is constructed.By optimizing the entry sequence,the change of operation efficiency and capacity before and after the optimization of entry scheduling is compared and analyzed.Finally,based on the above calculation and simulation,the feasibility of the model is verified,and the simulation results show that the proposed method can improve the runway capacity and operational efficiency.
