    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.
