相关的数据指公司从空管局、机场、航空公司获取的气象、航班信息、空域流量等数据。这些数据有些是公开发布的,有些则需要公司向空管局、机场和航空公司购买或交换。但这些都只是基础数据,要将它们变换成乘客所需要的简单明了的实时航班信息,还需要运用一套特殊的计算方法;
这套算法由研发人员从多年的民航系统工作经验中总结得来,已经申请了专利。《飞常准》是飞友科技做的一个App,它能帮助飞行旅客跟踪航班,提供延误智能预报;
乘机、接机、送机的旅客和民航业内人士可以通过《飞常准》网页和移动客户端查看国内所有航班的实时状态信息和精确的地图信息,提前了解影响航班准点的各种情况,实时获得航班的起飞、到达、延误、取消、返航、备降的六大类航班状态通报。用户还可以在《飞常准》客户端上定制个性化飞行计划,总结个人飞行记录。
航班数据,是指如气候、航班信息、空域流量等数据。这些数据的获取渠道为:
1)通过和国内航空公司、机场、空管建立合作来获取航班数据;
2)同国外数据服务商建立合作获取部分国际数据;
3)依靠自身建搭设的ADS-B设备来获取航班数据。(飞常准目前主要采用与机场合作搭建ADS-B设备的模式来收集航班动态数据)
我们现在从飞常准APP上所查询到的航班预计起飞/到达时间,是经过精密算法加工后的二次数据。这套算法由研发人员从多年的民航系统工作经验中总结得来,已经申请了专利。
举个栗子:
如何预测某次航班能否准时起飞?
首先,需要知道该次航班的飞机是否已经到达起飞机场。如果没有到达,是因为上一趟飞行延误了,还是飞机出了故障正在维修,或者已经换了另一架飞机?
如果该次航班的飞机已经抵达起飞机场,那么需要考虑起飞机场和目的地机场的天气状况。天气状况包括起飞时的天气情况和预计降落时刻的天气状况。两者中有一样出现异常,都可能影响飞机准点起飞。
如果天气也正常,那么要考虑空域流量是否受控制。比如,由于杭州萧山国际机场要优先考虑上海机场的航班起飞,其空域流量是受控的。
如果上述所有因素都正常,那么只需考虑机场当前的出港率(平均每架飞机的起飞时间)和排队等候起飞的飞机数量,将两者相乘,大致就能计算出目标航班的起飞时间了。
