    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.

    Overenie metodiky merania poklesu výkonnosti pri únave
    (University of Žilina, 2025) Rimarčík, Timotej; Kandera, Branislav
    Fatigue is a critical factor in aviation safety, contributing significantly to human error. This study aimed to validate a methodology for measuring performance decline due to fatigue, using both objective and subjective approaches. Eight university students participated in a two-day measurement involving psychomotor vigilance tests (PVT) for reaction time and self-assessment on the Karolinska Sleepiness Scale. Sleep duration was reduced to induce acute sleep disruption. Results demonstrated a measurable decline in cognitive performance, particularly on the second day following reduced sleep. A moderate positive correlation was found between subjective and objective measurements, confirming the validity of the dual-measurement approach. The study highlights the negative impact of sleep deprivation on performance and supports the methodology’s potential use in human performance education within aviation.
