Assessment of fatigue among aviation personnel involved in military flying in India employing Multidimensional Fatigue Symptom Inventory – Short Form (MFSI-SF)

Abstract

Introduction:: Fatigue has been recognized as a major safety hazard in modern aviation. There are numerous studies which have addressed various aspects such as the subjective symptoms, objective measures to diagnose fatigue, and its link with operator’s performance. This study was a novice attempt to assess the chronic fatigue among the aviation personnel employing “Multidimensional Fatigue Symptom Inventory – Short Form (MFSI-SF),” which is a well validated fatigue questionnaire. Material and Methods:: A total of 93 aircrew and 30 ground crew of either sex from three military air bases were randomly selected for this cross-sectional observational study. The selected participants were requested to respond to 30 items listed in the survey form based on various types of symptoms along with severity that they experienced in the preceding 1 week. Results:: The total fatigue score in case of the studied ground crew was higher than the studied aircrew group and this was statistically significant ( Conclusion:: Fatigue in either form, i.e., acute or chronic, could affect both aircrew and ground crew. The present study had revealed that the proportion of ground crew suffering from chronic fatigue was more than the aircrew. The aircrew who were found to have such type of fatigue were younger in age and experience in comparison to their counterpart ground crew. Among the ground crew, a large percentage of ATC crew had this form of fatigue.
