Boeing Flags 737 MAX Software Glitch That Could Affect Landings
波音披露737 MAX软件故障，或影响降落导航功能
Boeing has identified a previously undisclosed software glitch on the 737 MAX that could cause an automated navigation feature to fail during landing, the Wall Street Journal reported on September 26. The issue stems from a cockpit software update and can occur when flight crews change their planned flight path after a missed approach, or go-around. In certain circumstances, some autopilot functions can become unavailable, forcing pilots to fly the aircraft manually at a demanding moment. Boeing said it informed all 737 operators last month about the problem and is developing a fix. Southwest Airlines and United Airlines have reportedly asked Boeing not to deliver new jets running the affected software. The Federal Aviation Administration said it is assessing the issue and will act quickly if it identifies a safety concern.
据《华尔街日报》9月26日报道，波音公司发现737 MAX存在一个此前未公开的软件故障，可能导致自动导航功能在着陆过程中失效。该问题源于驾驶舱软件更新，当机组在复飞（放弃着陆后重新尝试降落）后更改预定飞行路径时可能出现。在某些情况下，部分自动驾驶功能会不可用，飞行员不得不在高负荷时刻手动驾驶飞机。波音表示，已于上月将所有737运营商告知该问题，并正在开发修复方案。据报道，西南航空和联合航空已要求波音不要交付搭载受影响软件的崭新飞机。美国联邦航空管理局表示正在评估该问题，若确认存在安全隐患将迅速采取行动。
