When aircraft taxing on the runway covered water at a certain speed,the hydroplaning will deteriorate the maneuvering of aircraft,even result in the brake failure. In this paper,the generation mechanisms of hydroplaning phenomenon are analysed,and the hydroplaning protections of the muti-wheel aircraft are introduced,from the runway, the tires, use skills and focus on the angle of the brake control system. Dynamometer test results show that the brake system owns the hydroplaning protection function, has an important significance in improving the aircraft safety.
