The Federal Aviation Administration (FAA) tries to reduce fatigue - and as a result, stress - by limiting pilots to logging no more than 8 hours of flight time over a 24-hour period. Pilots are also given a ten-hour minimum rest period before taking off.
After a series of accidents in the 1970s, a system was created called Crew Resource Management (CRM), which is designed to monitor stress levels and reduce the risk of human error in pilots. CRM training focuses on developing interpersonal communication skills, leadership, and decision-making, and helps pilots and crew members recognize signs of stress and fatigue in one another.
