摘　　要：在机动飞行较多的场景中,常用的单一距离门限评估方法无法有效识别机动飞行中的状态变化。为解决此问题,针对实际飞行活动中执行操作存在合理时间偏差的特点,根据起始转弯时刻分布,使用Monte Carlo方法建立内切转弯飞行位置分布模型,提出一种基于时间容差的飞行状态符合性评估方法,并使用实际飞行数据验证该方法的有效性。实验结果表明:该方法可有效表征内切转弯飞行状态的符合程度;相较于单一距离门限评估方法,可有效提前预警异常飞行状态,并提升评估结果的有效性与合理性。Changes of flight status during maneuvering flight cannot be effectively identified by common fixed distance threshold assessing method in senarios with large amount of maneuvering flight.To resolve this problem,aiming at the reasonable time variation during flight operation,and according to the initial turning time distribution,the fly-by turning position distribution model is built by Monte Carlo method and then the flight status conformance assessing method based on time tolerance is obtained.Practical flight data are used to verify the effectiveness of the current method and the results show that:this method can effectively demonstrate the fly-by turning flight status conformance extent;compared with fixed distance threshold assessing method,this method can effectively warn abnormal turning status in advance and improve the effectiveness and rationality of assessing results.
