Through a structured literature review and analysis of key milestones—ranging from Aristotle’s Meteorologica and early instruments (anemometer, barometer) to the establishment of Meteor R.E. in World War I, the METAR/TAF standardization in 1968, and the founding of ECMWF—this study highlights how terminology, data formats and distribution methods have continuously advanced. A comparative assessment of past and present practices reveals dramatic improvements in data timeliness (hours to seconds), measurement accuracy, and global coverage via SOS/AWOS, GTS/SWIM and satellite networks (MetOp, Meteosat). Finally, it examines emerging applications of AI and support vector machines for hyperlocal nowcasting and 4D trajectory planning, underscoring the need for ongoing international collaboration and technological innovation to meet the challenges of an ever-changing atmosphere.Item Výška základne oblačnosti na Letisku Žilina pri rozličných poveternostných situáciách(University of Žilina, 2025) Hromadík, Matej; Jarošová, MiriamThis paper focuses on the analysis of cloud base height at Žilina Airport under various weather conditions. The objective of the paper is to analyze the cloud base height in relation to atmospheric fronts, pressure systems, and associated meteorological phenomena that directly affect the safety of air operations, with particular emphasis on training flights conducted under Visual Flight Rules (VFR). The study utilizes METAR reports and synoptic maps provided by the Slovak Hydrometeorological Institute (SHMÚ). The months of August and November 2024, and January 2025, were selected for examination. Based on these data, an analysis was conducted of the occurrence of different cloud types, their base heights, and related weather phenomena such as fog, rain, thunderstorms, and reduced visibility. The results highlight typical cloud development patterns under specific synoptic conditions, contributing to better planning of air operations and enhancing safety, especially during training flights. The thesis also provides recommendations for increased attention during particular weather situations that may lead to limitations or complete suspension of flight operations.Item Vertikálne dohody EÚ o leteckej doprave a ich prínos(University of Žilina, 2025) Chlebák, Michal; Novák Sedláčková, AlenaThis paper examines the role of multilateral and bilateral air transport agreements concluded by the European Union in shaping the international aviation position of the Slovak Republic. It explores how EU membership has facilitated access to global markets while also imposing regulatory limitations that affect Slovakia’s ability to act independently. The paper highlights the challenges Slovak aviation faces, such as limited global connectivity and barriers to exporting advanced aerospace technologies. It further discusses strategic opportunities for Slovakia, particularly the potential for expanded cooperation with China and Canada. The findings suggest that proactive engagement in EU policymaking, modernization of export frameworks, and strengthening international partnerships are essential for Slovakia to enhance its competitiveness and secure a more prominent role in global aviation.Item Nové technológie vo všeobecnom letectve(University of Žilina, 2025) Imriš, Matej; Jůn, FrantišekThe final thesis focuses on the use of new technologies in the field of communication, navigation, and surveillance systems in general aviation.

In this thesis, the specific and limited-use applications that a UAV can carry out were written about. Which means that the drone was considered as a temporary device. This was done with the objective of observing the advantages of its use compared to different alternatives in the implementation in the same application and making recommendations for its correct implementation. For the analysis, four different applications were considered, including: infrastructure monitoring, security and rescue, terrain mapping, and photography and videography, within each application, unmanned aerial vehicles (UAVs) were compared to their conventional counterparts (listed on the pages 34-41), thus making it possible to identify the advantages that unmanned aerial vehicles have over the other alternatives. It was found that drones have the following main advantages: access to difficult or high-risk areas, speed in executing the application, and high precision when collecting information.Item Využitie nových materiálov v konštrukcií krídel lietadiel(University of Žilina, 2025) Jánošíková, Soňa; Jackuliak, JakubIn this Bachelor thesis, the topic of utilizing new materials in aircraft wings construction was addressed. The technical and physical properties of modern materials were examined in order to assess their potential to improve flight performance and reduce structural weight. The work includes an overview of the evolution from traditional materials such as wood, through aluminum and titanium alloys, to current composite materials. Parameters such as strength, weight, corrosion and fatigue resistance, as well as aerodynamic impact and sustainability, were evaluated. The study highlighted the significant advantages of modern materials, which enable weight reduction, increased strength, and improved aerodynamic performance of wings. A theoretical application of a new material was conducted, and its impact on flight performance was assessed through a conceptual design of the wings of the Discus-2 and ASW-19 glider models. To achieve the objective, computational methods based on MacCready’s theory, basic aerodynamic formulas, and available data from scientific sources were used. Parameters such as glide ratio, optimal speed, wing weight, and flight time on a 300 km course were evaluated. The conclusion of the thesis confirms that the application of innovative materials in wing structures represents a significant contribution to the further development of aviation, while also emphasizing the need for continued research and optimization of technologies.Item Letisko Piešťany a rozvoj leteckej dopravy s ohľadom na charakter regiónu(University of Žilina, 2025) Kocúrik, Filip; Novák Sedláčková, AlenaThis article is primarily devoted to the topic of Piešťany Airport and the development of air transport in this region.
