Abstract:This report is the second in a series on the physiological and psychological effects of flight operations on flight crews, and on the operational significance of these effects. This overview presents a comprehensive review and interpretation of the major findings. To document the psychophysiological effects of flying commercial short-haul air transport operations, 74 pilots from two airlines were monitored before, during, and after 3-day or 4-day trip patterns. Subjects wore a portable biomedical monitor which recorded core-body temperature, heart rate, and wrist activity every 2 minutes. They also rated their fatigue and mood every 2 hours while awake, and recorded sleep episodes, naps, showers, exercise, duty times, food and fluid intake, voidings, cigarettes, medications, and medical symptoms in a daily logbook. A background questionaire was administered which included basic demographic information,
sleep and life-style habits, and four personality inventories. A cockpit observer accompanied the crews on the flight deck and kept a detailed log of operational events. The supporting scientific analyses are described in detail in the rest of the text. Only the operational summary is available on line.
