Airport CCO/CDO Flight Program Design And Optimization

Starting from the design of CCO/CDO(Continuous climb operation,CCO/Continuous descent operation,CDO)flight program in airport terminal area,this paper studies the best CCO/CDO flight program path and the evaluation method of CCO/CDO flight program,so as to maximize the advantages of CCO/CDO flight program.Firstly,the airport topographic map is collected at the same distance according to the longitude and latitude grid.The more intensive the collection points,the more accurate the data screening will be.The second step is to select way points according to the operating specification DOC8168 with the shortest stable distance as the restriction condition.The CCO/CDO flight program is processed in sections,and the restriction function of each section is established.The map data screening model is constructed through Matlab.The third step is to combine the selected data matrices of each segment,and take the improved A* algorithm as the core algorithm of the program design.The optimized CCO/CDO flight program can be run and visualized through Matlab programming.Finally,use the autopilot function of the flight simulation software to evaluate and compare the flight time and fuel consumption of the optimized CCO/CDO flight program before and after the optimization,and use the noise evaluation model to evaluate and compare the noise impact of the optimized CCO/CDO flight program before and after the optimization.This study takes Guangzhou/Baiyun Airport as a verification case.First,the CCO/CDO flight procedures of this airport are compared with the PBN entry and departure procedures,and then the CCO/CDO flight procedures of Guangzhou Baiyun Airport are optimized by using the above research methods.Finally,the optimized CCO/CDO flight procedure is compared with the original CCO/CDO flight procedure of the airport in terms of flight time,fuel consumption and noise impact.The results show that the optimized CCO/CDO flight procedure has a greater improvement in flight time,fuel consumption and noise impact than the original procedure,and meets the requirements of flight procedure design.In summary,this research can provide CCO/CDO flight procedure designers with help in their program design ideas,and design the best CCO/CDO flight procedures,so as to give full play to the greatest advantages of CCO/CDO flight procedures.
