In late August, Boeing discovered a new software glitch on its 737 MAX planes that can disable an automated navigation feature during a missed landing approach. This issue arises when pilots change their flight path after aborting a landing attempt due to a cockpit software update. In certain scenarios, the plane's vertical navigation system (VNAV) disengages, leaving pilots without some autopilot functions at low altitude and potentially in challenging conditions like bad weather.
Boeing informed airlines that it does not consider this glitch a safety risk but is working on a permanent fix. The Federal Aviation Administration (FAA) is investigating the issue and could take action if it poses a safety concern. Southwest Airlines and United Airlines have opted to accept aircraft with an earlier version of the software, refusing new planes until the problem is resolved.
This incident follows previous scandals involving the 737 MAX, including two fatal crashes in 2018 and 2019, which led to a worldwide grounding. The recent glitch has raised concerns about pilot workload during critical moments when manual control might be necessary.
