Boeing discovers 737 MAX software malfunction may cause autopilot failure

Boeing (BA.US) has discovered a software fault in the 737 MAX that could result in the failure of its automatic navigation functionality, raising concerns about potential safety risks during aircraft landings. While Boeing has acknowledged this fault, it had not been publicly disclosed before. The fault originates from a cockpit software update and may occur when crew members change the set flight path after a missed approach. In certain scenarios, pilots may need to manually fly the aircraft with some autopilot functions disabled. Some industry insiders have pointed out that this could add extra workload for pilots, especially during already busy and low-altitude phases of flight, and when dealing with additional complexities such as adverse weather.
