Setting And Application Research Of Exit Taxiways

With the gradual arrival of the post epidemic era,the number of passengers in the civil aviation industry continues to recover and rise,and the airport scale and business volume are expanding.In order to improve the airport capacity,many airports begin to reconstruct and expand the exit taxiway.However,how to choose the configuration of fast exit taxiway,determine its specific location and number,in order to improve the safety and efficiency of aircraft ground operation,has become a difficult problem for airport planners and designers.Aiming at this problem,this paper starts with the design of exit taxiway,expounds the general design requirements of different exit taxiways,and summarizes the existing exit taxiway configuration and location selection.Secondly,as the landing process of aircraft is closely related to the design of exit taxiway,the landing process and its influencing factors are analyzed,and the runway components are introduced and improved.Then,the four stages of aircraft landing are analyzed and modeled in detail,and the landing distance and the time of occupying runway components in each stage are expressed by mathematical model.The optimal turning out position of aircraft and the total weighted average time of occupying runway components under different aircraft types and different wind speeds are obtained by MATLAB,which is an important basis for the selection of exit taxiway configuration,location and quantity.An example shows that this method is more reasonable than the method given by ICAO in the airport design manual.Then,the minimum weighted average occupancy time of runway components in peak hours and the maximum number of aircraft sorties that can be operated are calculated by adding take-off models,setting different take-off and landing ratios,and different exit taxiway configurations and numbers in the case of mixed operation of single runway airport.The feasibility of the method is verified through the analysis of examples.Finally,an example is simulated by Anylogic to further prove the feasibility of the theoretical method.This paper studies the setting and application of exit taxiway in detail,not only gives the general physical and plane design requirements of exit taxiway,but also includes the selection of configuration,location and quantity determination method in specific setting,which provides theoretical reference for airport planning and design personnel in airport plane layout planning,airport reconstruction and expansion.
