    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.

    KONSPEKT AKVIZÍCIE GEOPRIESTOROVÝCH DÁT PRE VYTVORENIE 3D MODELU REFERENČNÉHO LETISKA
    (Žilinská univerzita v Žiline, 2020) Škultéty, Filip; Janovec, Michal
    When rendering large scenarios for flight simulators, we encounter similar problems as in the case of scenes for cinematography or computer games. In the case of this work, we solve the rendering of the earth's surface for any camera configuration, and we try to maximize the quality of the rendered images without a visible decrease in the rendering frequency. The article is devoted to the creation of a reference model of the Piešťany airport (LZPP) as a part of the scenery for a certified flight simulator. The presented solution maintains a stable 60 frames per second when rendering the airport surface from any distance and direction.

    ROZPTÝLENIE POZORNOSTI PILOTA GNSS PRIJÍMAČOM POČAS VFR LETU
    (Žilinská univerzita v Žiline, 2020) Ondrejková, Ivana; Škvareková, Iveta
    The main goal of this paper is to propose a methodology for measuring the distraction of pilot attention by GNSS receivers during flight in visibility. To carry out future research, we will use a vision tracking device, thanks to which we can monitor the collocation of the pilot's attention during individual tasks. There search will be attended by three pilots in training, according to the number of flying hours, they will be classified as beginner, intermediate and advanced. Testing will take place on the flight simulator L410 UVP-E20, which is located in the premises of LVVC ŽU at the airport in Dolný Hričov. The aim of the work will be to find out if and how much the GNSS receiver disturb the pilot during the flight in the flight level and during the visual approach to landing regarding to his experience and the number of flying hours. Subsequent analysis of the data provided by the questionnaires showed that a pilot with more flying hours, detailed theoretical knowledge and longer experience with a GNSS receiver should be less disturbe and should be able to effectively distribute his attention among all instruments. While a pilot with less number of flying hours without theoretical knowledge and previous experience with a GNSS receiver should be disturbed and inconsistent during visual landing.

    TVORBA MODELU REFERENČNÉHO LETISKA PRE GENERÁTOR OBRAZU LETOVÉHO SIMULÁTORA
    (Žilinská univerzita v Žiline, 2020) Poláček, Jozef; Škultéty, Filip
    This paper describes the fundamentals of creating reference airport scenery for the X-Plane flight simulator. The work contains other acquired knowledge that is necessary or useful in the process of creating a scenery for a flight simulator image generator. The introductory part of the work focuses on the history, development and importance of flight simulators and image generators, it points out the importance of their constant development and quality improvement. The theoretical part of the work is mainly focused on defining the basic file types, their description and information about the usage of the rendering pipeline. In the practical part, the work focuses on Bratislava and Piešťany airport scenery development for the X-Plane flight simulator and on the subsequent possibility of using these sceneries for image generator of the L-410 UVP-E20 flight simulator, which is currently operated by the University of Žilina.
