    Changes in visibility caused by atmospheric fronts
    (University of Žilina, 2023) Valo, Sebastián; Jarošová, Miriam
    This scientific thesis deals with the research and analysis of atmospheric fronts and their effect on visibility focused on aviation in Žilina airport, Poprad – Tatry airport and Košice airport. For the purposes of research and analysis of changes in visibility due to the atmospheric fronts passing through, METAR reports from the above-mentioned airports and bulletins of meteorology and climatology published every month were used. We analyzed reports from 2017 to 2021, a 5-year period. In this thesis, there is also an atmosphere with its layers, fronts and visibility. This scientific thesis was developed under the supervision of the thesis supervisor. For the analysis, we used METAR reports provided by the Slovak Hydrometeorological Institute.

    Fuels for carbon neutrality in aviation
    (University of Žilina, 2023) Valášek, Denis; Čerňan, Jozef
    Aviation is one of the fastest-growing industries, but its contribution to greenhouse gas emissions cannot be ignored. In recent years, the development of alterna-tive fuels for aviation has gained increasing attention to reduce carbon emissions and achieve carbon neutrality. This thesis provides an overview of the current situation in aviation, focusing on the use of conventional jet fuels and the need for alternatives. Various types of alternative fuels for aviation are presented, including biofuels, syn-thetic fuels, and hydrogen. The dvantages and disad-vantages of each type of fuel are analysed, as well as the current production methods and their potential for com-mercial use. With a greater focus on biobutanol as an alternative fuel.

    The COVID-19 crisis and its impact on changes in air transport
    (University of Zilina, 2022) Zermeghová, Michaela; Novák-Sedláčková, Alena
    The aim of this paper is to identify the effects of the corona crisis on air transport and the changes that this crisis has brought. It deals with the analysis of selected airlines, navigation service providers and airports from the EU (Slovakia, the Czech Republic, France), the United Kingdom, the USA and the United Arab Emirates, whose economic indicators as well as economic and operational results show how the measures in place affect their operation. The aim of this paper is to provide a comprehensive view of how air transport has changed as a result of the pandemc COVID-19, as well as to make proposals for revitalization measures to help the aviation sector.

    VPLYV LETECKEJ DOPRAVY NA ŽIVOTNÉ PROSTREDIE
    (Žilinská univerzita v Žiline, 2020) Turkinevych, Yelyzaveta; Jarošová, Miriam
    The relevance of the topic is due to the fact that in the transport sector, the aviation industry is one of the sources of global warming and climate change. The average number of flights worldwide is up to 102,465 per day, and this number is constantly growing, which has a major impact on the climate. Climate change is currently a huge problem, global warming is evident and unquestionable. It follows that our effort to conquer nature is a great threat to all of humanity. The aim of this work was to analyze the impact of air transport on the environment from several perspectives. The work is divided into three parts. The first chapter describes the historical development of the issue in the world. The second chapter deals with the analysis of global warming and destabilizing environmental factors. There are descrribed different types of ecological pollution. The last third part discusses ways to minimize the impact of aviation on the environment.

    VPLYV AUTOMATIZÁCIE NA LETOVÉ ZRUČNOSTI PILOTA
    (Žilinská univerzita v Žiline, 2020) Zermeghová, Michaela; Škvareková, Iveta
    Air transport is the most dynamic and fastest growing transport sector. However, along with the increase in frequency, the demand for safety is also rising. The development of air transport has brought a number of automated systems that make work easier for pilots. Over time, however, in addition to the positives, negative signs of progress began to show. The bachelor thesis deals with the study of the influence of automation on the flight skills of a pilot. The author explains the basic concepts of the human factor and automation, while also dealing with the history of the development of automation and a comparison of the philosophy of the two largest aircraft manufacturers in the world. It also analyzes the contribution of human causes to air accidents. It examines the current state of the impact of automation and compares various studies with the views of pilots.
