Abstract:

Estimation of landing distance on wet and contaminated runway is particularly important to ensure the safety of aircraft landing in actual operations. By applying multiple linear regression model,research is conducted on the landing distance estimation. Utilizing the least square to solve the equation of multiple linear regression firstly,and then using the"F test","t test"and"R test"to test the regression equation,finally,the theoretical formula is given to estimate the aircraft's landing distance on wet and contaminated runway. The results of simulation show that the method is effective and feasible.

Key words: wet runway, contaminated runway, landing distance, multiple linear regression model, least square
