国产大型客机C919在今年5月5日成功首飞后,于9月28日再一次起飞。

澎湃新闻记者从中国商飞获悉,28日7时20分许,C919大型客机101架机从浦东机场第四跑道起飞,经崇明至南通,试飞空域据称比首飞时要大一倍,预计当日11时左右返回浦东机场。

据新民网报道,28日凌晨4时30分,C919飞机保障人员、保障车队已经过安检进场,管制中心监控小组、遥测指挥车队等陆续到位,5点15分,试飞指挥大厅开启,人员进场监控准备。随后,C919机组出发,进行绕机检查和登机检查。试飞人员一切按计划,有条不紊开展飞行计划。

这也是C919时隔146天再次起飞。

据新民网报道,9月6日,C919就在浦东机场第五跑道开展了滑行试验,但随后一段时间受天气和空域条件影响,试飞排期一再拖延。等待飞行的日子里,C919还要进行一系列试验试飞以及相关测试。

C919的下一个目标,是完成近1400公里的空中航程,转场至中国试飞院所在的西安阎良。

新民网报道称,出于安全考虑,首飞时,C919飞行高度3000米,飞行速度也仅有170节,全程没有收起落架。转场的话,就必须飞得更高、更快,起落架也要像正常航班那样,起飞后收起,降落前放下。

在转场前,C919要以浦东机场为基地,进行密集试飞,每次时长都在3个小时左右,飞行空域要比首飞时大出一倍,一共有超过30个试飞科目,200多个试验点需要完成。
