历史航班准点率

航班在最近30天里准点程度的参数综合，反映了该航班可能延误的概率指数。具体计算方法：在最近30天内，航班降落时间比计划降落时间（航班时刻表上的时间）延迟半小时以上或航班取消的情况称为延误，将出现延误情况的航班数量除以30天内实际执飞的航班数量得出延误率，准点率=1－延误率。每日全面更新一次。This comprehensive parameter quantifies the on-time performance of a specific flight over the past 30 days, serving as a probabilistic index reflecting the likelihood of flight delays. The specific calculation method is as follows: Within this 30-day period, a flight operation is categorized as delayed if its actual landing time is delayed by more than 30 minutes compared to the scheduled landing time (the time specified on the official flight timetable) or if the flight is cancelled. The delay rate is calculated by dividing the total number of delayed flight operations by the total number of flights actually operated for this specific flight during the 30-day window, and the on-time rate equals 1 minus the delay rate. This dataset is fully updated once daily.
