摘　　要：为了有效评价飞行学员进近过程中的手动操纵能力,提出一种基于功率谱密度原理的操纵稳定性评价模型。首先选取影响进近飞行安全且与飞行操纵直接相关的飞行参数,计算其功率谱密度图;然后统计功率谱密度图的低频部分功率占比和高频部分的总功率定量评价学员的操纵稳定性;最后选取飞行学员的进近数据对模型进行实例分析和验证。结果表明,该模型评价成绩和专家评分吻合,且更能区分学员间的细微差异,可以应用于日常飞行训练对飞行学员操纵品质的评价。该模型是对学生直接操纵过程的评价,可以直观反映学员的操纵习惯,有利于增强学员的手动操纵能力,促进飞行训练质量提升。In order to effectively evaluate the manual control ability of pilot trainees during approach,a control stability evaluation model based on the principle of power spectral density is proposed.First,select flight parameters that affect approach flight safety and are directly related to flight control,and calculate their power spectral density diagram;then calculate the power ratio of the low-frequency part of the power spectral density diagram and the total power in the high-frequency part of the power spectral density diagram to quantitatively evaluate the control stability of the trainees;Finally,the approach data of pilot trainees are selected to analyze and verify the model.The results show that the evaluation results of the model are consistent with the expert scores,and can better distinguish the subtle differences between trainees.It can be applied to the evaluation of pilot trainees'handling qualities in daily flight training.This model is an evaluation of the students'direct control process,which can intuitively reflect the students'control habits,is conducive to enhancing the students'manual control ability and promoting the improvement of flight training quality.
