基于功率谱的飞行操作技能评价方法

Evaluation method of flight operation skills based on power spectrum

为定量评价飞行员的操作技能,基于飞行快速存取记录器(Quick Access Recorder,QAR)数据,应用功率谱原理建立了一个飞行技能评价模型。模型可依据功率谱图定性分析飞行操作,依据平均功率频率及中值功率频率指标定量评价飞行员操作技能水平,最后应用从航空公司采集的QAR数据验证了模型的实用性和可靠性。结果表明,该模型使用方便,计算结果直观、准确,能够应用于飞行运行部门评价飞行员的操作品质。模型的进一步软件化可为航空公司评价飞行操作绩效、改进飞行训练提供参考依据和支持。

For the aim of quantitatively evaluation of the flight operation skills,a flight skill evaluation model is developed based on the Quick Access Recorder（QAR） data and the power spectrum method.The model can qualitatively analyze the flight operation according to the power spectrum diagram; the average power frequency and the median power frequency could be set as quantitative evaluation index of flight operation skills. Finally the QAR data collected from airlines was used to validate the model. The results show that the model is easy to use and the calculation process is accurate,and can be applied to evaluate the operational quality of pilots in airlines. Based on this model,applicable software could be developed to provide technical support for airline＇s flight performance and training improvements.
