The invention relates to the technical field of aviation, in particular to a method and a system for predicting a wake flow safety area during pairing approaching of an aircraft, and the method comprises the steps: collecting pairing approaching environment parameters and front aircraft parameters; the paired approaching environment parameters and the front aircraft parameters are substituted into a preset wake flow dissipation model, the front aircraft tail flow dissipation condition is obtained, the wake flow dissipation model is constructed based on a wake flow model, and the wake flow model is constructed based on the distribution relation of the double-vortex intensity and the velocity field of the aircraft; the method comprises the following steps: acquiring rear aircraft parameters, judging a wake flow danger area by combining front aircraft tail flow dissipation conditions, respectively calculating displacement changes of the wake flow danger area caused by turbulent flow, ground effect and crosswind,
