The aim of the article is to confirm or refute the influence of climate change on the increasing frequency of meteorological phenomena in the specified time frame from 2000 to 2019 by means of a comprehensive statistical analysis and statistical summarization of meteorological data. The first part of the article defines the basic terminology related to the climate change and specifies the importance of addressing the issue in the context of aviation safety. For the practical part of the article meteorological reports provided by the Slovak Hydrometeorological Institute were used. In the practical part, various statistical methods, and a comprehensive evaluation of the frequency of individual weather phenomena during the analyzed years, were used. The hypothesis of increasing frequency of weather phenomena over the years was statistically confirmed only for thunderstorm activity at one meteorological station.Item Měření parametrů větru na palubě ultralehkého letadla(University of Žilina, 2025) Kaltman, Lukáš; Novák, AndrejThis article addresses the issue of measuring wind parameters onboard ultralight aircraft with the aim of increasing pilot safety by providing relevant information about current weather conditions, specifically wind speed and direction. The theoretical part of the article analyzed the influence of wind on the flight characteristics of ultralight aircraft and examined existing wind monitoring options. Subsequently, an analysis of aircraft accident and incident data involving ultralight aircraft in the Czech Republic and Slovakia between 2019 and 2023 was conducted, revealing that wind negatively influenced 41 % of the analyzed events in the Czech Republic. Based on these findings, three potential solutions were proposed: establishing RADIO service at airfields for sport flying devices, installing windsocks at the ends of runways, and installing onboard electronic flight instrument systems capable of indicating the wind component. Using multi-criteria analysis, the installation of onboard instruments was evaluated as the most suitable option, as it offers the most accurate and up-to-date information directly during flight. In the experimental part, this option was preliminarily verified through two control flights at Sazená airfield using Garmin G3X systems. Comparison of data from the onboard instrument with data from ground meteorological stations showed that while the first flight yielded unrealistic results, the second flight showed better agreement, especially for wind direction, and the data from the onboard instrument corresponded more closely with the pilot's observations and the METAR report. It was concluded that onboard systems represent a promising solution, but more extensive research is necessary for definitive confirmation of their reliability. The article successfully identified a key risk factor, proposed a promising technical solution, and provided a theoretical and methodological basis for further research, thereby contributing to the main goal of increasing the safety of flying ultralight aircraft.Item Návrh na zlepšení plánu strategického rozvoje Letiště Ostrava(University of Žilina, 2025) Kapitanov, Alexandr; Badánik, BenediktAirports are not only essential transport hubs, but also dynamic centres of economic growth, technological progress and global connectivity.
