Aviation network risk assessment method

The invention discloses an aviation network risk assessment method. According to the method, on the basis of a single airport risk, more serious airspace risks brought by risk cascading are studied, airspace-oriented risk assessment is carried out, and control over the overall airspace operation situation is facilitated. And on the other hand, the potential safety risks such as airport saturationand flight delay are selected as evaluation factors, the risk evaluation and adjustment measure making time points are advanced from the factors causing the aviation network risk in the pre-tactical stage, the risk evaluation and adjustment measure making time points are not developed into major flight accidents such as collision, and tactical-level high-risk operation is reduced. Meanwhile, flight delay and airport saturation are dynamic, so that aviation network security risk assessment based on delay and congestion is dynamic, and risk level assessment of each airspace of the whole aviationnetwork is more reliable.
