This article discusses Boeing's efforts to resolve a software issue impacting the 737 MAX aircraft family. The problem pertains to the automated flight guidance system, which may incorrectly switch modes during specific landing approaches after a missed approach. Although Boeing states it does not pose a safety concern, several airlines, including Southwest and United, have requested delays in deliveries of affected aircraft while a software fix is developed.
The flaw was initially communicated to operators in August, involving potential misbehavior of the flight management computer following crew-initiated flight path modifications. Boeing is actively working on a software update under FAA oversight and is collaborating with airlines to establish procedures that allow pilots to manually re-enable automated vertical navigation if needed.
This issue emerges at a critical time as Boeing prepares for certification of the 737-7 and delivery of the 737-10, the final variant of the MAX family. The manufacturer emphasizes that pilot training and existing procedures sufficiently address these scenarios, and the FAA has been notified to ensure regulatory compliance. The resolution of this software issue is expected to be incorporated into upcoming aircraft deliveries, supporting safety and project timelines.
