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.
An analysis of the observations and experiences in regard to the new format of snowtam report
(University of Žilina, 2023) Drábek, Marek; Kazda, Antonín
This paper presents a new ICAO methodology for assessing and reporting runway surface conditions, commonly known as the Global Reporting Format (GRF) and its impact on flight crews and airline operation. It explains the background of the system and its effect on safe operation. Furthermore, it compares the current format of the SNOWTAM message with the old one applicable until November 2021. It also presents research which aims to enhance winter operations safety by gathering observations and experiences with the new format of a SNOWTAM report applicable as of 2021. The paper points out the experiences of flight crews gathered with a survey created by the author of this thesis. It also summarises the impact of the new methodology on airplane performance calculations backed by the research. The new system is expected to provide better understanding of the runway situation and give clearer information about contamination of the movement area.

(University of Zilina, 2021) Kohútová, Alžbeta; Kazda, Antonín
The aim of the paper is to assess the catchment area of Žilina Airport in terms of inbound tourism, to consider the possibilities of its further development, and to assess potential traffic flows. The first chapter is devoted to the evaluation of current state and accessibility of the region within the realm of air travel. The second chapter describes the acquired theoretical knowledge about tourism which served as a basis for the Žilina Airport catchment area specification, as well as for defining activities, organisations and facilities crucial for the development of inbound tourism in the area. Another part of the final paper is a short questionnaire which details the interest of spa facilities in the airport catchment area to attract groups of clients who utilised air travel. The results obtained from the questionnaire served as a basis for the last chapter which describes potential customers and traffic flows.
Changes in airport infrastructure caused by the historical development of aircraft
(University of Zilina, 2022) Adamík, Jozef; Kazda, Antonín
The airport infrastructure is constantly influenced by the development of aircraft. It has always been, that the aircraft was first designed, and based on its performance parameters and geometrical characteristics, a space for the airport were sought to serve the new aircraft. Even today, we can see the different development of aircraft in different aircraft manufacturers, which determine how the airport infrastructure will change in the future. In the introductory chapters, we analyze several aircraft requirements for airports that have been affected by changes in ground infrastructure and the subsequent development of airports. The main objective of this bachelor thesis is to document the changes in the airport infrastructure caused by the historical development of aircraft. The discussed development of aircraft and reaches out from the beginning of aviation to the end of World War II through the era of jet aircraft to large-scale long-haul aircraft. Based on the creation of a database of aircraft and a description of typical aircraft representatives of the period, an analysis of their parameters and the described impact on selected airports is performed. Three historical international airports were selected for a detailed analysis of airport development. There are two analyzed airports in Europe: Munich Riem together with Munich - Franz Josef Strauß and Amsterdam Schiphol. In the United States, John F Kennedy Airport is chosen near New York City in terms of the highest airline utilization. Until 1951, selected airports were analyzed from historical footage and, after the publication of ICAO Annex 14 Aerodromes, also documented by changes in the regulation. Airports had to adapt to changes in environmental requirements and the introduction of new technologies in the form of more fuel-efficient and smaller commercial aircraft. One of the benefits of the thesis is to emphasize the need to plan airport changes in relation to the needs of aircraft technology in the future. This area includes the planning and modernization of runways (RWY), terminals, aprons and stands. At present, RWY design pays attention to reducing noise in suburban areas, reducing turn-round time at stands by using jetways, the number of taxiways (TWY) connecting the RWY to the airport and operating aircraft with a smaller code letter.
Implementation of a new RWY reporting system and snowtam format in slovak republic
(University of Zilina, 2021) Drábek, Marek; Kazda, Antonín
This paper presents the upcoming changes in the runway reporting format and the newly introduced SNOWTAM format. The aim of the paper is to draw comparisons between the current SNOWTAM format and the updated version applicable as of November 2021. The author analysed information from available documents published by the International Civil Aviation Organisation ICAO, which describe the general conditions adopted to the new runway condition reports formulations. Since the author is enrolled in his pilot training, his objective when writing this final thesis, was to understand the issue of the changes. From this knowledge he can benefit in his future carrier. The paper points out new formats of reports of airport movement areas reporting conditions. As the new reports and techniques of reporting have not been used in real conditions yet, the author based the paper on the ICAO standards and recommended practices, ICAO and EASA guidance material. Introduction of the new methodology is expected to provide a better understanding of reports informing about contamination on movement areas, to ensure more precise aeroplane performance calculations and enhance the safety.

One of the most important partial results is analysis of existing low-cost carrier’s business models, describe their historical evolution and propose future modifications to stay competitive and profitable.
MOŽNOSTI VYUŽITIA ODNÁMRAZOVACIEHO POOLU NA LETISKU LKPR
(Žilinská univerzita v Žiline, 2020) Straková, Silvia; Kazda, Antonín
The paper deals with the possibilities of using the the de-icing pool at a selected airport. The selected airport for this paper was Prague / Ruzyňe Airport. The current state of de-icing is not ideal. In the winter, there are situations when icing forms on aircraft and it is necessary to remove it. The problem arises when there are more aircraft to be cleaned from icing, but they can only be de-iced by companies which they had concluded contracts. This causes inefficient use of de-icing vehicles. The final work describes the current method of de-icing on the airport. Part of the work ic the characteristics of the airport, including information about de-icing stands, de-icing fluid warehouses and de-icing providers. From the information provided by Prague Airport, a comprehensive overview of information on the current capacities of providers, their vehicles and employees is created. The work also present data on the amounts of liquid used. The following are the legislative requirements for the de.icing pool and some examples of pooling from other areas. The work also provides the reader with specific proposals for de-icing pools, and based on what-if analysis, their benefits and risks associated with their implementation are evaluated. The last part presents a proposal for an optimal model of the de-icing pool for Prague Airport.

POROVNANIE VÝCVIKOVÝCH OSNOV PILOTOV V ČESKOSLOVENSKU Z OBDOBIA I. SVETOVEJ VOJNY A II. SVETOVEJ VOJNY
(Žilinská univerzita v Žiline, 2020) Beťková, Kristína; Kazda, Antonín
This paper covers the topic of the training curricula of pilots from the beginning of World War I till the end of World War II in Czechoslovakia. The purpose of this thesis was to focus on the process of the development of the training and factors, that affect this development. Since the author is in pilot training too, she considered it to be interesting enough to find out what was the development of the training and further process of adaptation, that she could later compare to the training she is a part of. The author obtained information mostly from description of historical events, that were substantiated by facts of evolution of aircraft. In the beginning, the thesis covers pilot training in the nowadays society and by obtaining additional information using the historical procedure, in individual chapters the author analyzes the functionality of training centers during particular periods, the characteristics of aircraft technology, the requirements imposed on pilots, the training itself and its development. Ultimately, the author concludes that the aircraft technology and the demands placed upon pilots during their career are the predominant causes of changes in training and, on the other hand, finds that the political situation, which used to affect the training during World War I and II greatly, is nowadays pushed to the background.

Súčasný stav a rozvoj systému pohybových plôch na letisku M. R. Štefánika
(University of Žilina, 2024) Adamík, Jozef; Kazda, Antonín
In view of the dynamic development of air transport, it is essential that airport infrastructure is adapted to the requirements of modern aircraft. The thesis analyses the historical development of the infrastructure of M. R. Štefánik Airport (BTS). This research involves guided interviews and questionnaires with seven experts of practice who provided insight into the current state of the BTS airport. These experts were selected from five different areas, including BTS Airport, Air Navigation Service Provider (LPS), noise and vibration assessment (Euroakustik company), runway systems capacity, and the perspective of the Bratislava Metropolitan institute. The aim of the thesis is to propose appropriate recommendations for BTS Airport, the main proposal being the use of one runway (RWY) in 'mix mode' instead of using both RWYs at the same time. This proposal is supported by the cost of the RWY reconstruction, which has been compared with other airports in Europe and North America. To validate the capacity of a single RWY, the Airfield Capacity Spreadsheet Prototype Model (ACRP 79) will be used, in which several inputs have been adjusted according to BTS airport operations such as: aircraft operating from BTS airport, aircraft separations, aircraft approach speeds, and RWY occupancy time. The model simulates operations in August and December 2023 and projected operations in 2028. Other recommendations include modification of some taxiways (TWY), apron modifications, and analysis of the use of jetways on the apron stands. Finally, the impacts of a possible restriction of airport Curfew at BTS are also being examined.
