ABSTRACT
Currently, the most erroneous element during the flight operation is a human. Regarding to continuous efforts spent on increase of the air transport safety level, a greater attention is now focused on human factors and comprehension of the factors having a negative impact on pilots and other crew members. The main goal of this study is to evaluate the fatigue effect on pilot performance during at least 24-hour measurements. The whole measurement consisted of two-hour time blocks, during which the pilot was flying, then the reaction time was measured and at the end psychological tests were conducted. The reaction time was chosen as an indicator of short-term performance. The study involved 4 pilots (men aged 21–27 years) with a given pre-flight regime. The results show that even though the pilots experienced a gradual fatigue during the measurements, it did not manifest in reaction times measurements. It can be stated, that despite the fatigue, the pilots are able to maintain short-term attention and maintain constant performance.
