    Identifikácia prekážok v okolí letiska lzzi prostredníctvom leteckého laserového skenovania
    (University of Žilina, 2025) Švancár, Denis; Škultéty, Filip
    The article focuses on the identification of obstacles in the vicinity of Žilina Airport (LZZI) by means of airborne laser scanning technology. The main objective of the thesis is to identify the limitations of this technology in determining the location and height of potential obstacles in the vicinity of Žilina Airport that could threaten the safety of air traffic. The subsequent values found were compared with the requirements set by the International Civil Aviation Organization (ICAO). The results showed that the LiDAR technology enables satisfactory identification of obstacles interfering with the airport obstacle planes. A number of vegetation obstacles were identified that interfere with the obstacle planes of Žilina Airport. The accuracy of the data collection met the requirements set by ICAO PANS-AIM for the areas surrounding the airport. The work confirmed the time efficiency of airborne laser scanning when used over vegetation obstructions in the wider vicinity of the airport.

    Komplexné modelovanie prúdenia okolo viaczložkových konfigurácií
    (University of Žilina, 2025) Timková, Monika; Pecho, Pavol
    V diplomovej práci bola riešená problematika návrhu a analýzy viaczložkových zakončení krídla s cieľom zlepšiť aerodynamické charakteristiky nosnej plochy. Študovaný bol vplyv dvoch konfigurácií typu wing-grid – s prvkami v rôznych výškach a s prvkami v jednej línii. Cieľom bolo navrhnúť riešenia prispievajúce k zníženiu indukovaného odporu, zvýšeniu vztlaku a zlepšeniu aerodynamickej efektívnosti. Navrhnuté 3D modely boli analyzované pomocou simulácií v softvéri Autodesk CFD pre rôzne uhly nábehu. Výsledky viaczložkových konfigurácií boli porovnané s referenčným krídlom a blended wingletom. Pre overenie simulácií bol vytvorený zmenšený model testovaný vo veternom tuneli. Na základe analýz bola určená najefektívnejšia konfigurácia, pričom sa potvrdilo zlepšenie aerodynamickej efektivity a mierne zníženie indukovaného odporu.

    Integrácia bezpilotných leteckých systémov
    (University of Žilina, 2025) Valášek, Denis; Kandera, Branislav; Nichtová, Radoslava
    This article explores the integration of unmanned aerial systems (UAS) into civil airspace, focusing on collision avoidance technologies and remote identification systems. As drone operations expand, ensuring safety and interoperability becomes essential. The study reviews systems such as TCAS, ACAS, ADS-B, and FLARM, and highlights their adaptability for UAS. EU regulations 2019/947 and 2019/945 are addressed with regard to Remote ID requirements. Practical testing of Dronetag Beacon Gen. 2 and Aerobits TR-1F at Žilina Airport demonstrated accurate and stable data transmission, confirming their suitability for UAS integration. The findings underline the need for both technological innovation and regulatory alignment to safely merge manned and unmanned traffic.

    Riešenie výpadku systému a nedostatku personálu pri odbavovaní cestujúcich na letiskách
    (University of Žilina, 2025) Valo, Sebastián; Rostáš, Ján
    With the growing volume of air transport, airports are increasingly dependent on digital check-in systems and the availability of qualified personnel. System outages and staff shortages represent two key challenges that negatively affect the efficiency and fluency of the passenger handling process at airports. This article analyses the current situation at selected airports in Slovakia and the Czech republic, evaluates the causes and consequences of these issues, and proposes concrete solutions, including organizational, technical, and staffing measures. Research results, based on surveys and interviews, highlight the needed for greater airport preparedness for unexpected situations and emphasize the importance of technological modernization.

    Dopady emisných systémov na letecké spoločnosti
    (University of Žilina, 2025) Velčický, Ján; Novák, Andrej
    This paper analyses the impact of emission systems on airline operations, with emphasis on EU measures (ETS, ReFuelEU) and global mechanisms (CORSIA). It compares regulatory frameworks, technological options and airline strategies in the context of reducing emissions by 2050. A combination of methods was used, including qualitative analysis of documents, scenario comparisons (LTAG), and quantitative assessment of economic effects. The findings show that EU tools alone are insufficient without additional measures. The thesis proposes a combined approach that integrates technological, operational and behavioral components, including fuel diversification, compensation schemes and innovative policies. The result is a realistic strategy for the decarbonization of European aviation, aligned with long-term targets and taking into account SAF, hydrogen, and infrastructure risks. The objective of the thesis to propose an effective decarbonization rajectory while minimizing financial impacts on carriers was achieved.

    Optimalizácia riadenia UAV: analýza ľudského faktora a jeho vplyv na bezpečnosť a efektivitu prevádzky
    (University of Žilina, 2025) Zacharová, Alexandra; Pecho, Pavol
    Currently, the use of unmanned aerial vehicles (UAVs) is on the rise, which implies that care must be taken to ensure safe operation. Safe operation depends on several factors, not only technical but also, to a significant extent, on the human factor, the human factor. This paper aims to investigate the impact of the human factor, specifically the impact of cognitive ability, stress and reaction time of pilots on stress reactions in various simulated emergency situations. The goal of the research is to optimize flight procedures and minimize the negative impact of the human factor on UAV control. In the experimental part, the research addresses the variability of heart rate (HRV) and electroencephalographic (EEG) data that were measured during UAV control in the presence of simulated critical situations. Other measured parameter such as reaction time, maneuver accuracy or stress response provide important information about the neurophysiological load of operators. Thus, the outcome of the study is to identify critical situations, analyze decision-making processes and propose streamlined training procedures for UAV operators.

    Alternatívne metódy navigácie bezpilotných lietajúcich zariadení
    (University of Žilina, 2025) Močková, Chiara; Dianovský, Robert
    This article deals with the analysis and comparison of alternative navigation methods for unmanned aerial vehicles (UAVs). The aim of the article is to evaluate the effectiveness of selected navigation systems in conditions where traditional GPS-based methods may fail. The introduction presents traditional navigation methods and their limitations. The article focuses on alternative solutions such as visual navigation, celestial navigation, radio signal-based positioning, and inertial visual odometry (VIO). In the final part, the practical implementation of a visual navigation system using drone imagery and satellite images is described, along with the evaluation of its reliability at different flight altitudes. The results confirm the high potential of visual navigation as an independent or complementary system for UAV operations.

    Nízko-nákladové podnikanie leteckých dopravcov na dlhé vzdialenosti: úspešný a perspektívny model?
    (University of Žilina, 2025) Tomová, Anna; Švancárová, Nikola
    The paper discusses some costs and revenues aspects of long-haul low-cost business model of air carriers. The paper confims that the average lifespan of long-haul low-cost carriers has increased in time, supporting in this way the research of competitive advantage of such business model. According to the paper´s findings, existing long-haul low-cost carriers are differently hybridized, and therefore we can pronounce that there is more than one long-haul low-cost business model. In this regard, it is questionable whether the concept of long-haul low-cost carrier is proper in current academic terminology and whether the traditional classification of air carriers business models is still inspiring for academic esearch and managerial practise as well.
