The invention discloses an airplane take-off and landing early warning method based on a flight simulation platform and a wind measurement laser radar. According to the method, a built-in flight dynamics solver JSBSim of a FlightGear platform is compiled into a dynamic link library; a wind profile of a take-off area and a wind profile of a descending area are measured in real time through a wind measurement laser radar, a flight path is predicted by calling a JSBSim dynamic link library and related flight scripts, a flight data result is displayed on a user interface through a UDP interface, and danger early warning of airplane take-off and landing is achieved. Early warning is carried out according to the flight parameters and the aircraft trajectory, so that a user can more intuitively judge the influence of wind shear and turbulence on the aircraft, and the efficiency and accuracy of early warning of danger are improved. The method is used for guaranteeing the safety of takeoff andlanding of the civil aircraft, and has the advantages of high flexibility, high response speed and high accuracy.
Description
technical field [0001] The invention relates to the fields of flight simulation technology and wind-measuring laser radar, in particular to an aircraft take-off and landing warning method based on a flight simulation platform and wind-measuring laser radar. Background technique [0002] In recent years, aviation flight safety has attracted much attention. Wind shear is one of the main culprits in the downfall of large airliners. Low-altitude wind shear is the change of wind vector from one point to another point in the space below the height of 600m, which is the vector difference of wind speed between two points. Encountering low-altitude wind shear will cause an instantaneous change in the speed of the aircraft, which in turn will cause a change in the lift of the aircraft, causing the flight track to deviate from the course and cause an accident. The international aviation community believes that the consequences of wind shear during the entire flight mainly seriously a...
