Description

technical field [0001] The invention relates to an aircraft route optimization method, in particular to a weather grid-based aircraft route optimization method. Background technique [0002] When an aircraft flies in the atmosphere, it will be affected by meteorological conditions. Meteorological conditions mainly affect the flight characteristics of the aircraft through aerodynamics. Therefore, it is necessary to plan and optimize its route in real time according to the current and forecasted future weather conditions to ensure its flight efficiency. and security. The existing meteorological parameters used for route optimization have the problems of low precision, small range, and slow data refresh, which seriously affect the effect of route optimization. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a route optimization method based on meteorological grids with high precision and large range of meteorological pa...
