【Abstract】 A downburst is modeled using a technique of fuzzy logic method, the influence of high on an A300 aircraft during powered approach is analyzed, and two different dimensional models are compared. The results show that the fuzzy logic model can display the dynamic qualities of the airplane well. Some important conclusion was made by analyzing the influence of initial high on the plane. The physical qualities of low altitude windshear can be further comprehended.更多还原
