    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.

    The issue of glycaemia and heart rate variability of flight crew during emergency situations using HRV corsense elite
    (University of Zilina, 2022) Pudíková, Alžbeta; Škvareková, Iveta
    The purpose of this article is to research the issue of glycaemia and heart rate variability (HRV) of flight crew, while these physiological processes are investigated during emergency and abnormal situations on the flight simulator. Stressful situations, which pose dangerous emergency situations for pilots during the flight, raise blood sugar level to ensure the brain has enough glucose during stressful situations. The attention is also given to assessing the effect of fasting blood glucose on flight crew performance, stress and heart rate variability. We try to focus on the overall evaluation of the impact of the above physiological processes during flights in which selected emergencies occurred in order to increase the level of stress hormone – cortisol, which is produced during workload and stress. The autonomic nervous system and its parasympathetic and sympathetic branches affect the heart functioning and its activity. The methods used to measure blood glucose and heart rate variability are non invasive methods of measurement. The survey compares the results of measurements from samples of ten pilots studying the field of professional pilot. As proper eating habits are important for safe flight, we are trying to find out how the absence of food for at least 12 hours can affect pilot’s performance as well as heart rate variability in the research.
