中文摘要：
通过研究航迹误差分布规律,制定合适的航路宽度标准是提高空域利用率的关键所在。基于ADS-B数据对航迹误差分布规律进行了研究。在对A593航路ADS-B数据进行解析的基础上,采用Q-Q（quantile-quantile）图和Jarque-Bera检验法对数据进行正态分布检验,进而运用基于参数估计的统计方法对航迹误差分布进行计算。结果表明,飞机实际位置点与航路中心线的偏差距离符合正态分布规律,为进一步研究基于ADS-B的飞行安全间隔提供了依据。
英文摘要：
To increase the airspace utilization,the standard of air route width was constituted by researching the laws of flight path error distribution.The paper researches the laws of actual flight distribution based on ADS-B flight path information.The methods of Quantile-Quantile plot and Jarque-Bera were proposed to put normally distribution test on the data.Then,a statistics based on parameters estimation was used to calculate flight path error.The result shows that the deviated distance between aircraft actual position and airway centerline obeys the normal distribution.The condition for the further research on flight safety separation based on ADS-B was created.
