    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.

    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.
