从分析RNAV/RNP运行对航空器飞行时机载设备的性能特点出发,说明了RNAV/RNP运行初期对飞行品质的监测要求和意义,并就QAR数据作为监测数据源进行了精度分析,表明其可用性,进而给出了一种通过处理QAR数据,反演实际飞行的仿真轨迹,与设计轨迹之间实现了直观比对,并计算给出了比对差值的均值与方差,实现了监测飞行品质的目的。
Based on the analysis of the performance characteristics of on-board equipment during the flight of RNAV / RNP, the requirements and significance of flight quality monitoring during RNAV / RNP operation are described. The accuracy of QAR data as monitoring data source is analyzed to show its availability , And then gives an intuitive comparison between the design trajectory and the simulated trajectory by processing the QAR data, inverting the actual trajectory of the flight and calculating the mean and variance of the calculated difference, so as to realize the monitoring of flight quality the goal of.
