Simulation of Extended Range Flight Plan Consideringthe Change of Regulations
With the continuous updating of the relevant regulations of the Civil Aviation Administration and the imminent commercial operation of the domestic C919,it is of great significance to establish a domestic flight plan sys-tem that can adapt to the changes in regulations and independently control key technologies.First of all,the core con-cept of extended range operation(ETOPS)and its flight plan production process are summarized.Then,the iterative method is used to solve the windless equal-time point,and the linear interpolation method is used to calculate the wind and temperature at a specific time and space point,so as to obtain the key information of the ETOPS flight plan such as the equal-time point,the diversion fuel,the diversion distance,and the fuel critical point.Finally,a flight from Xiamen to London is taken as an example.The research results show that the ETOPS flight plan-making process and solving algorithm are of high accuracy,and the flight plan-making program written using Python software is feasi-ble,which can provide a reference for the development of domestic flight plan systems.
