Pilots must handle a higher volume of manual tasks during aircraft descents after Boeing discovered a technical flaw in the 737 MAX's automated landing systems. This software glitch disables navigation features and could postpone the delivery of the company's newest narrowbody models, according to a report by the Wall Street Journal.

The malfunction impairs automated approach functions, cutting off essential flight guidance during the final descent to a runway. Boeing is working to fix the instability to resolve the safety risk and prevent further delays to the arrival of its latest planes.
