According to CCAR, the airplane which apply for cross ocean flight should do some airworthiness compliance on floatation after ditching. Because of the imperfect method in this area, we can not obtain the exact result which restrict the level promoted for airplane design. So an distinct and easy method is needed imminently. In this paper, we build a calculate method of attitude motion for flotation on hydrostatics, time domain and stepwise regression theories. Though decompose the yield of water into tiny part and make use of the relationship between float time and yield of water, we develop a software which is good at analyse the float time on the basic of CATIA If we study the flotation character in this way, we may save much time and simplify the complex question. In the end of this paper, we analyse the floatation for an airliner and the result shows that rhythms by calculate is good accord with that of experiment which declare the rationality of that method.
