Análise da Fadiga Humana Em Controladores de Tráfego Aéreo Com Foco Na Prevenção de Acidentes Aeronáuticos

This paper aims to analyze fatigue as a human factor contributing to aeronautical accidents within the scope of the Air Traffic Control of the Brazilian Air Force (FAB), focusing on prevention and on the technical perception of flight safety, to contribute to the preservation of human and material resources. For this study to be possible, the methodology was used through exploratory research, of an applied nature, with a qualitative approach, using the following sources as a data collection technique: documentary analysis of the Air Force Command, national and international legislation, semi-structured interview with specialists in the field and the researcher's observation. As results found, it was possible to identify fatigue as the main human risk factor for air traffic controllers. For this reason, the FTA (Fault Analysis Tree) was applied as a risk identification tool in the execution of the process. The application of this tool in the aeronautical accident prevention process showed that although 66.39% of accidents are due to operational risk factors, the greatest evidence relates to operational aspects related to pilots who, sometimes, have little experience and, also, the failures related to the decision-making process, which corroborates with 32.95% of accidents related to human risk factors. In addition, the implementation of the FAST (Fatigue Avoidance Scheduling Tool) software is proposed to measure the operational performance of the Air Traffic Controller through sleep monitoring, to avoid the state of fatigue. Finally, it is suggested the use of Fatigue Performance Indicators to provide a mechanism for continuous improvement of operational safety, aiming to prevent the occurrence of accidents evaluated in the FTA.
