Fatigue in Aviation: A Survey of the Awareness and Attitudes of Indian Air Force Pilots

This study was undertaken to develop an understanding of fatigue among aircrew of the Indian Air Force and how fatigue may affect flight safety. A total of 83 military fast jet aircrew members with a median age of 28.9 years and an average military service of 7.2 years participated in questionnaire study. Findings showed that the majority of the aircrew tended to sleep more in the afternoon and longer in the night on holidays and weekends. One-third of the aircrew believed that they could perform in peak efficiency even with 1 to 2 hr sleep loss. A similar number stated that they had felt sleepy or drowsy in the cockpit due to sleep deprivation. Aircrew rated decreased attention, increased reaction time, lapses in concentration, and poor aircraft handling as important outcomes of fatigue. Tea or coffee was the preferred countermeasure. They were unanimous in the felt need for more information dissemination on fatigue. They also are not well versed about the beneficial effects of napping when fatigued. The overall findings indicate that there appears to be complacency and overconfidence among aircrew who believe that they may be able to operate with full flying efficiency despite 1 to 2 hr of sleep loss.
