Percepção da Fadiga Humana No Desempenho Operacional dos Controladores de Tráfego Aéreo Sob A Perspectiva Das Equações Estruturais

This article aims to present an analysis of the perception of human fatigue as a contributing factor in the operational performance of operators working in air traffic control in uninterrupted twenty-four-hour shifts. For this study to be possible, the methodology was used through exploratory-explanatory research, of an applied nature, with a quantitative approach, using the following sources as a data collection technique: document analysis of the Air Force Command, national and international organizations, brainstorming with specialists in psychology, investigation, and prevention of aeronautical accidents, and air traffic control. A survey was applied to contain 44 objective questions to collect information related to human fatigue that impacts operational performance through the perception of operators who work in operational bodies. As a result, obtained through the 108 responses, the partial least squares structural equation modeling (PLS-SEM) was applied, which revealed that, according to the perception of the interviewees, the model explains the operational performance in 34.7 %, alertness by 29.9%, and reaction time by 31.2%. Thus, it is expected that from this research, the proposed suggestions related to the variables will be implemented to preserve the professional's health and operational safety.
