The invention discloses a scheduled flight trajectory optimization and translation method and system. The method comprises the following steps: acquiring flight time sequence data of an aircraft in an approaching stage; obtaining the optimized longitude and latitude values of the kth point from the flight time sequence data; according to the optimized latitude and longitude value of the kth point, the true course of the aircraft at the kth point and the flight distance between the kth point and the (k+1)th point, calculating the optimized latitude and longitude value of the (k+1)th point; wherein the kth point and the (k+1)th point are points in the flight time sequence data; sequentially calculating the optimized latitude and longitude coordinate values of the subsequent points of the starting point until the flight falls to the parking space; according to the optimized longitude and latitude coordinate values of each point, connecting the optimized longitude and latitude coordinate values in sequence, and generating an optimized scheduled flight trajectory; and according to the optimized scheduled flight trajectory, realizing overall translation of the flight trajectory by taking the position of the grounding point as a reference. The flight trajectory is more accurate and smoother, and the flight trajectory is more smoothly displayed in combination with geographic information.
