波音“飞行出租车”试飞成功 或被用于货物运输
美国波音于当地时间23日宣布，基于自动驾驶的“自主载人飞行器(PAV)”试验飞行取得成功。试制机采取自动控制，像直升机那样垂直起飞，完成在空中静止的悬停之后着陆。飞机的自动驾驶有望被用于空中出租车和货物运输，或将推动开发竞争。
波音于2017年收购的涉足自主飞行系统的新兴企业极光飞行科学公司(Aurora Flight Sciences)自1年前启动试制机的开发。此次，在垂直方向的起降上取得成功。据称在下次试验中，将挑战被认为难度更高的向前高速飞行。
试制机为电动，设计在50英里(约80公里)的范围内进行自主飞行。波音除了PAV之外，还在推进可运输最多500英镑(约226公斤)货物的“货运飞行器(CAV)”的开发。据称2018年完成了室内的试验飞行，年内将转为室外试验。
网约车企业优步(Uber)也在推进自动驾驶小型飞机的开发，力争2023年实现飞行出租车的商用化。如果飞机的完全自动驾驶得以实现，有助于缓解飞行员和卡车司机的短缺，整理面临的课题和制定规则的行动已经展开。
