    Danger of icing when operating unmanned aerial vehicles
    (University of Žilina, 2022) Ondrejková, Ivana; Kandera, Branislav
    The paper examines icing on Unmanned Aerial Vehicles (UAV) during the flight. We chose the Mavic Pro and Mavic 2 Pro UAV by company DJI to carry out the research. Research flights are performed during the early morning hours with meteorological conditions suitable for icing. We use the AirData application to analyse flight data. The aim of the work is to find out how dangerous icing is, what meteorological conditions are suitable for icing, how fast icing is formed during the operation of an unmanned aircraft and how it is possible to suppress or eliminate icing. In introduction of this work elaborated theoretical knowledge about the formation of icing and its types. Subsequently, the negative effects of icing on the flight are described, such as changes in lift, drag, controllability of the aircraft and others. The following section describes the accidents of UAV due to the impact of icing. After analysing the data from the mentioned application, we proposed recommendations for pilots of UAV. Before the flight, we recommend checking the meteorological forecast, focusing on the temperature and humidity at the flight area, usually up to 120 meters above the Earth surface. In-flight recommendations include monitoring rotation speed of propellers and frequent inspection of propellers in meteorological conditions suitable for icing and others.

    Airport operation disruptions
    (University of Žilina, 2022) Beťková, Kristína; Kazda, Antonín
    Disruptive events have a very strong potential to create a problem, spreading onwards to different participants in the chain of air travel. To minimalize the negative effects, this paper focused on how an airport can deal with disruptive operations effectively. The target of this paper was to come up with a step-by-step method, that airports could follow when coming up with a plan on how to manage their operations during these events. In order to reach this goal, it was essential to understand the principles causing disruptions and furthermore, categorizing them respectively. In addition to that, we had to find out what is the contribution of each category to the overall state of delays. Thanks to interviews with professionals at different international airports, we were able to come up with plans of trainings and exercises as a part of the suggested strategy. At the same time, in the proposed plan, several factors were mentioned, which were considered as an important part of the operations during interruptions that airports should not forget about.

    Influence of stress on the performance of pilots in training
    (University of Žilina, 2022) Goldschmidt, Jakub; Kandera, Branislav
    This paper deals with the influence of stress that affects pilots in training, how stress affects their daily lives, but especially how it affects their concentration and performance during pilot training. It describes what risks, whether mental or physical, can occur to pilots in training. It also discusses about the factors that affect pilots. One of the factors is the kinetosis, to which more attention is paid and which had also become the subject of the research in this diploma thesis. The aim was to use a questionnaire to find out whether the pilots in the training encountered signs of motion sickness during the training, how it affected their concentration and how they dealt with these situations. In conclusion, based on these responses, we suggested possible preventive solutions for other future novice pilots on how to avoid motion sickness and if it had already occured, how it should be eliminated as much as possible not to affect performance and concentration of pilots.

    Baggage policy of European airlines
    (University of Zilina, 2022) Kožušník, Jozef
    The purpose of this article is to research the baggage policy of European airlines. Its main objective is to identify groups of European airlines based on the used baggage policy and to compare the baggage policies of selected European air carriers in terms of cost-effectiveness for a passenger. The current state of baggage policy research, focusing mainly on the United States, has highlighted the lack of comprehensive research on European air carriers' baggage policies. Therefore, the actual research in this paper examines European airlines' carry-on and checked baggage policies and their charging. It then uses two model cases to compare the baggage policies of selected airlines in terms of cost-effectiveness for the passenger and examines the pricing applied to baggage fees. The research results in the determination of the most advantageous booking method with respect to baggage fees. Simultaneously, three groups of European airlines were identified according to the baggage policy used

    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.

    China as a new competitor on the global market of civil aircraft
    (University of Zilina, 2022) Krajčo, Tomáš
    This paper deals with the Chinese aviation industry and its current state, and the main goal of this paper is to find out whether China, in terms of its position, can compete with the current Airbus-Boeing duopoly in the coming years on the large civil aircraft market, while it also aims to set possible scenarios of the development of the large civil aircraft market. The paper approaches the matter through the historical development and the current state of the large civil aircraft market to find out whether there is any perspective and chance for a new competitor to succeed, and the Chinese aviation industry, which allows a better understanding of the problems that China faces in the production of large civil aircraft. In the third chapter, a comparative method is used and its result is the determination of the competitiveness of large civil aircraft produced by China in comparison with those produced by European and American manufacturers, while it also points out their strengths, weaknesses and potential customers. In the last chapter of the paper, the “Compound Annual Growth Rate” method is used along with findings gained from pervious chapters in order to determine possible development scenarios of the large civil aircraft market regarding the position of China. While determining the scenarios, the current and possible future geopolitical situation, political relations of China and the resulting factors with the potential of affecting the Chinese aviation industry were taken into account. This paper also points out China’s biggest problem, due to which, despite the enormous effort, it has not yet entered the market of large civil aircraft, with the problem being the dependence on foreign aviation technologies caused by the lack of expertise and experience stemming mainly from the historical development of the Chinese aviation industry. The paper also points out that, despite the slow development of the Chinese aviation industry, the entrance of China to the large civil aircraft market is only a matter of time. The results of paper about diploma thesis can be used to help to decide what threat China does pose to the Airbus-Boeing duopoly.
