It was observed that the helicopter pilots in graduating at the First Squadron of the Eleventh Aviation Group (1st/11th GAV)
returned from flight with intense sweating, symptoms of physical fatigue and wheezing. Subjectively, many pilots ascribed a reduction in performance because of the effects of heat on cabin. To verify the scientific basis, this work was performed to investigate the influence of heat stress on performance of pilots in training. Thus, this work was conducted in two phases: the first one based on the presentation of concepts proposed by the theoretical framework and the second one in field research, where data were collected through a questionnaire, meteorological records and flight data. The obtained data were analyzed from the viewpoint of the concepts presented and by calculation of statistical correlation. In this work, we could check signs of physiological order compatible with the condition of thermal stress and environmental conditions of the flight deck of the helicopter H-50 Esquilo, in-flight instruction given by 1st/11th GAV, are outside the range of thermal comfort. After the correlation of the variables involved, it was found that 61% of pilots had their performance in-flight negatively affected by heat stress, yet at low intensity.
