摘要
在实际运营中,估算飞机在湿跑道、污染跑道上的着陆距离对飞机的安全着陆有着重要的意义。对运用多元线性回归模型估算飞机的着陆距离进行了研究,首先采用最小二乘法对多元线性回归方程求解,然后利用"F检验"、"t检验"、"R检验"对回归方程进行检验,最后给出估算湿跑道、污染跑道着陆距离的拟合公式,仿真结果表明该方法有效可行。
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.
