Route planning method, device, equipment and medium

The invention discloses an air route planning method, device and equipment and a medium, and the method comprises the steps: generating an air route network diagram based on preset air route data; cutting the air route network diagram according to a preset starting point and a preset ending point to obtain a local air route network diagram; based on the route data, preset meteorological data, aircraft initial weight, flight height and flight cost index, calculating an edge weight value corresponding to each leg in the local route network diagram; and according to the edge weight value corresponding to each leg, a plurality of target route points with minimum cost estimation values between the starting point and the ending point are determined by using an A * algorithm, and a target planning route is determined according to the starting point, the plurality of target route points and the ending point. According to the method, the edge weight value and the cost estimation value are calculated in real time in th
