    Analysis of selected vital functions of a pilot during flight
    (University of Žilina, 2023) Rimarčík, Timotej; Chodelka, Frederik
    Pilots work in distinct environment and there are many requirements they must fulfill to ensure the safe operation of an aircraft. However, there are also some psychological elements, that might be difficult to deal with, such as stress and high workload, while performing difficult flight tasks. This article explains what causes stress and high workload, and how does it affect pilots. Some of the vital functions of human body can be used to measure stress and high workload. The final part will deal with some research, using modern methods to measure stress and high workload during different flight phases, to upgrade cockpit ergonomics and procedures in aviation.

    Influence of stress on the performance of pilots in training
    (University of Žilina, 2022) Goldschmidt, Jakub; Kandera, Branislav
    This paper deals with the influence of stress that affects pilots in training, how stress affects their daily lives, but especially how it affects their concentration and performance during pilot training. It describes what risks, whether mental or physical, can occur to pilots in training. It also discusses about the factors that affect pilots. One of the factors is the kinetosis, to which more attention is paid and which had also become the subject of the research in this diploma thesis. The aim was to use a questionnaire to find out whether the pilots in the training encountered signs of motion sickness during the training, how it affected their concentration and how they dealt with these situations. In conclusion, based on these responses, we suggested possible preventive solutions for other future novice pilots on how to avoid motion sickness and if it had already occured, how it should be eliminated as much as possible not to affect performance and concentration of pilots.

    Utilization of biofeedback for examination of differences in reaction to workload between inchoative pilots and chosen students outside of training program
    (University of Zilina, 2021) Novák, Andrej; Škvareková, Iveta
    Paper describes research applications of biofeedback on psychological resistance analysis. Using scientific methods paper evaluated influence of stress and mental resistance of probands: pilots in training so-called cadets and volunteers not involved in piloting of any kind, so-called „nonpilots“. Devices Muse 2 and CorSence Elite are used to examine R-R intervals, sympathetic/parasympathetic activity ratio and brain activity during each examination sessions. Theses also aim at answering two core hypotheses. Do the pilots have greater mental resistance against stress due to training and frequent exposure to a highly stressful environment? And, are we able to find the answer to the previous question using the biofeedback examination method? Nonpilot group had 2,47 times thinner R-R interval than the pilot group and also had SNS index 1,77 times higher than the one in the pilot group. Unusual data can be observed once we look at the PNS index. According to data calculations, the final PNS index in the pilot group is 0,816 and the nonpilot group 0,7075 This situation can be described by the known effect of physical subsystems which can deviate these indexes. Significant differences between examined values verify hypothesis which says frequent exposure to highly stressful environment causes high mental resistance against stress for pilots. It is also safe to say that cardiologic biofeedback is a reliable tool for complex examination of induces stress levels. It wasn’t managed to verify MUSE 2 technology due to inconclusive data. It is believed that distortion of data from MUSE 2 is a consequence of a hygienic face mask. This exposure of its weakness shows brand new information for using such technologies.

    Measuring of pilot workload
    (University of Zilina, 2021) Plichta, Dávid; Škvareková, Iveta
    The aim of our paper is to analyse the issue of measuring of workload and subsequently carry out our own measures of pilot workload on pilots of different skill level. These measures took place in a simulator, mainly due to safety of air traffic. The chosen phase of flight had been approach and landing, which represents the most difficult phase. We had also chosen two airports, where one presents an airport known to the pilot and the other unknown. This decision relates to the opinion, that the pilot workload is significantly lower has he experience with the airport
