    The impact of the COVID-19 pandemic on the economic performance of the European air carriers
    (University of Zilina, 2022) Mikulášiková, Michaela
    The outbreak of the COVID-19 pandemic which was officially declared in March 2020 as a whole new global risk, has negatively affected operations in all industries around the world. Air transport was one of the first sectors to be affected the most by this event as the disease has been easily transmittable among people. As a measure to prevent the spread of the disease, governments around the world have severely restricted international commercial air traffic. These travel measures have significantly reduced the market value of airlines operating scheduled passenger air services worldwide, where operations have had to be largely limited or even canceled by air carriers. These facts motivate to research the impact of the COVID-19 pandemic on the performance of air carriers, which is also the main aim of this paper. This paper examines the impact of the COVID-19 outbreak on 15 European airlines using economic analysis of the influence of the determining factors.

    TVORBA ŠTUDIJNÝCH MATERIÁLOV – NAVIGAČNÉ SYSTÉMY
    (Žilinská univerzita v Žiline, 2020) Mikulášiková, Michaela; Novák, Andrej
    The aim of this paper is to present current navigation systems and their use in air transport. Describing their history, categories, principles of operation and practical use. The paper also deals with the problems of navigation systems in determining the accuracy of positioning and errors that may occur in determining the position. It focuses primarily on the current, most advanced navigation systems, called the Global Navigation Satellite Systems (GNSS) used to determine the exact location of an observer on Earth. It describes the function and accuracy of systems such as American GPS, Russian GLONASS, European Galileo and Chinese BeiDou and points out their importance in navigation. It also compares the quality of individual systems. It deals with the construction, structure, principles of operation and factors that influence their resulting positioning accuracy. The augmentation navigation systems SBAS, GBAS and ABAS, which are closely related to GNSS systems are also mentioned in this paper.
