||Fatigue in two-pilot operations: Implications for flight and duty time limitations
||Nov. 2008, Vol.79, No.11, p.1047-1050. Illus. 7 ref.
||Fatigue is an important consideration in two-pilot commercial flights as there is little opportunity for in-flight rest. This study investigated the role of duty length and time of day on fatigue. Pilots flying two-pilot operations ranging from 3-12h completed fatigue ratings prior to descent at the end of each flight over a 12-week period. A total of 3023 usable ratings were collected. It was found that time of day had a marked effect on the pattern of fatigue at the start of the duty and on the rate at which fatigue levels increased, with the highest levels in the circadian low (from 2 to 6 a.m.). Fatigue also increased with the length of duty and was 0.56 points higher at the end of a two-sector compared with a single-sector duty. Implications of these findings are discussed.
