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 reflects the on-time performance of flights over the past 30 days, serving as a probability index indicating the potential delay risk of a flight. The specific calculation method is as follows: Within the past 30 days, a flight is classified as delayed if its actual arrival time is more than 30 minutes behind the scheduled arrival time (the time listed on the flight schedule) or if the flight is canceled. The delay rate is calculated by dividing the number of delayed flights by the total number of flights actually operated within the 30 days, and the on-time rate is equal to 1 minus the delay rate. This parameter is fully updated once daily.
