Abstract：This paper analyzes lading procedure of planes in plateau.In view of taking the converted friction coefficient as its model being not suited for calculating a plane slipping length in plateau airfield by the ex-isting standard method,the paper establishes a mathematic model on a plane landing at plateau airfield un-der the condition of the influence of break performance and the location,and puts forward a calculation method for friction coefficient based on relationship between the velocity and the friction coefficient in breaking,And the paper writes a plane slipping length progress in language Visual C++.Through on-site test in plateau,maximum absolute error of test length and the computed length measured practically by type-I aircraft does not exceed by 48 m,and its maximum relative error does not exceed by 2.7%;the maximum absolute error of test length and the computed length measured practically by type-II aircraft does not exceed by 100 m,and the maximum relative error does not exceed by 4.2%.The result shows that the calculation model can be used for calculating slipping length in plateau airfield,and the model is high in precision and is wide in calculation scope.
