Abstract: According to the characteristics of flight data，a novel combined method in missing flight data complement is proposed.This method combines the advantages of the B-spline curve fitting and Least Squares Support Vector Machines（LSSVM），and processes the results of single method with weighted mean.The reliability of the method is strengthened，and the precision in flight data complement is enhanced with the combined method.The contrastive experiment results show the feasibility and applicability of the combined method.

摘要： 针对飞参数据的特点，将B样条曲线拟合和最小二乘支持向量机相互结合，提出了一种缺失飞参数据填补的组合方法。该方法将两者优势互补，对单一方法的填补结果进行加权平均，增强了算法的可靠性，提高了数据填补的精度。对比实验的结果表明了方法的可行性和适用性。
