The invention provides a large aircraft test flight method based on crosswind data and a crosswind monitoring device. The method comprises the steps that a test flight runway is determined according to test flight requirements, the crosswind precision, the crosswind speed and the data sampling frequency parameter requirements are determined according to aircraft crosswind test outline parameters, and the aircraft placing direction, the test flight course and the aircraft starting position are determined; current natural wind direction and wind speed data are collected and transmitted to a data monitoring and processing platform; the data monitoring and processing platform calculates and determines the crosswind speed according to the test flight course and the natural wind direction and speed data collected in real time; the data monitoring processing platform calculates a crosswind speed average value under a set time step to obtain a crosswind sliding average value; and when the test requirements are met, crosswind test flight is executed. According to the invention, the problem that the large aircraft crosswind test flight space is limited due to the too short wired signal transmission distance in the existing aircraft test flight is solved; and compared with the wind speed and the wind direction which change quickly, the method is more accurate by taking the crosswind sliding average value as the test flight basis.
