The Scientific journal AEROjournal is published by The Air Transport Department at the University of Zilina. It offers aviation professionals and academics an opportunity for publication of their research outcomes covering wide range of current issues in air transportation. The Air Transport Department at the University of Zilina (ATD) is a centre for education, research, and training in civil aviation. ATD provides accredited study programmes in a three - tier course structure of university education - bachelor, Ing (equivalent to MSc.) and PhD degrees. We also provide complex aircraft pilot training up to the CPL/IR/MEP (A) level (Commercial Pilot with twin-engine aeroplane qualification and qualification for flying in accordance with Instrument Flight Rules) and a theory up to the frozen ATPL (Airline Transport Pilot) level including Multi Crew Cooperation course. ATD is also the base of the National Civil Aviation Security Training Centre of the Slovak Republic. The Centre runs basic aviation security courses in line with the EU regulations for all categories of personnel in aviation. The papers in this journal cover all the aspects of aviation (including airlines, airports, air traffic management, aerospace and maintenance).

Advancements in VDL and CPDLC: revolutionizing European aviation communication
(University of Žilina, 2023) Novák, Andrej; Kováčiková, Kristína
The paper is focused on the transformative impact of VDL and CPDLC on aviation safety, efficiency, and reliability. Tracing the historical evolution from radio systems to the adoption of VDL and its integration within Europe's unified airspace initiatives, this paper deals with key theories including VDL Mode 2, ACARS, Aeronautical Telecommunication Network, ADS-B, and CPDLC. Emphasizing interdisciplinary collaboration to tackle communication challenges, the paper spotlights CPDLC's evolution integrating AI, Machine Learning, cybersecurity protocols, and technological integrations like 5G and satellites. Human-Computer Interaction research underscores user-friendly CPDLC interface designs. Methodologies encompass operational analyses, communication protocols, avionics technologies, and usability testing. Aligning with the Single European Sky initiative, the integration of VDL and CPDLC anticipates emerging trends while addressing challenges like interoperability, training complexities, and cybersecurity vulnerabilities through proposed solutions. The paper offers a comprehensive understanding of advancements shaping the modern aviation communication landscape.
Traditional air carriers fare and booking class names as a part of their marketing strategy
(University of Žilina, 2023) Sitarčík, Adam; Materna, Matúš; Šajbanová, Kristína
This paper focuses on the issue of fare and booking class names of traditional air carriers. Paper discusses the issues of traditional air carriers, history, development and current status, fleets, airline networks, services offered as well as mutual alliances. The article also focuses on the market analysis of the offered class names of the traditional air carriers divided by region. Paper includes an analysis of the data obtained in clear tables regarding preferred names of classes.
Creation of a Z 43 aeroplane model for a flight simulator
(University of Žilina, 2023) Poláček, Jozef; Škultéty, Filip
This paper describes the process of developing a Zlin Z 43 aircraft for a flight simulator. Work on an aircraft simulation consists of multiple parts. The development of the flight model is the first and core part of the simulation. Work on this part consisted of an analysis of the X-Plane blade element theory-based flight model, sourcing of the data this model requires, flight testing and further editing of the data to match the known performance of the Zlín Z43. The aircraft systems are another core part of the simulation. A Mix of the simulator's default, customised and fully custom systems are used. The theory and process of creating, animating, and texturing a 3D model are described, too. Visual quality can also be important, especially for its use in virtual reality. The last part is about the user interface, user experience and how the various use cases shape their design for an aircraft simulation.
Long-range UAV hybrid petrol-electric powertrain
(University of Žilina, 2023) Uhlár, Erik; Pecho, Pavol
Along with increasing UAV both weight load and endurance requirements, there is a need to use alternative propulsion solutions, to satisfy the market as well as various customer applications. Although lithium polymer cells are yet well developed, they are still too heavy for long-endurance UAV missions. Hybrid petrol-electric powertrains are outstanding imitations of hybrid hydrogen-electric propulsion systems, which are currently under intensive development. Not only for their onboard power production and improved overall efficiency but also for simulating a weight load of a future hydrogen-electric system. Therefore, such a system is being tested and aimed to be used in fixed-wing UAVs for long-endurance missions. This paper describes the design and operation of a hybrid petrol-electric propulsion system and further operational optimization based on comprehensive ground testing.

Uplatnenie pilotov v praxi medzi rokmi 2019-2022
(University of Žilina, 2023) Švancár, Denis; Chodelka, Frederik
The article about application of pilots in practice between years 2019 – 2022 deals with issue of the employment of pilots in these years. It examines the beginning of the problems with employment of pilots, which started with the Boeing 737 MAX crisis and the subsequently crisis of Covid-19 pandemic. The article is further supported by research on the application of the participating respondents in the field during crises and their application after the lifting of security measures and resumption of air transport. Finally, the article is aimed at visions of employment opportunities of students/pilots in 2023.
Detekcia rušenia signálu GNSS na letiskách
(University of Žilina, 2023) Velčický, Ján; Novák, Andrej
Although the Global Navigation Satellite System provides an increased precision in instrument approaches, it is vulnerable to various signal interferences causing either decreased position accuracy or a complete loss of GNSS signal reception. One of the major threats to a GNSS receiver is the intentional interference known as jamming. Incoming airplanes can be seriously endangered by such signal loss. This bachelor’s thesis addresses the detection and classification of possible unintentional and intentional interference and spoofing attacks on airplanes in proximity to the airdrome Žilina. Besides that, other systems which show sufficient reliability are compared. Additionally, critical parts of RNP approach chart map are evaluated. Finally, a device called HackRF ONE is selected to be put in aerodrome proximity for detection of possible GNSS interference. Using this software defined radio as unmanned aerial vehicle alarm and protection system is another suggested possibility.
Vplyv pandémie na kvalitu služieb poskytovaných na letisku
(University of Žilina, 2023) Kováčiková, Kristína; Baláž, Martin; Kováčiková, Martina; Vaculík, Juraj
To keep pace with the rapid evolution of airports, it is essential to integrate multiple systems and smart solutions within the airport. However, the integration of such technology requires significant time, patience, and financial investment. The focus of this paper is on the quality of airport services in the aftermath of the pandemic. The pandemic has provided an opportunity for many airports to adopt smart technologies and solutions, which promote safety and provide passengers with a seamless, contactless experience. The objective of this study is to evaluate the current state of airport services following the pandemic by conducting primary research among airport passengers.
Identifikácia možností využívania alternatívnych palív v letectve
(University of Žilina, 2023) Lehocká, Paulína; Rostáš, Ján
The article focuses on the possibilities of using alternative fuels in the field of air transport with the aim to show the process of production and use of various alternative fuels from both economic and ecological point of view. One of the main themes of my work is the comparison of different types of alternative fuels according to different criteria. In the technical paper, I have also discussed the projects already existing or planned in the future by leading aircraft manufacturers, which aim to implement alternative fuels in the aviation sector. The aim of the paper is to analyze and evaluate the prospect of the full use of these concepts and the fuels used by them in the future in terms of economic use of resources, sustainability, but also efficiency, and their subsequent comparison and inclusion in practice.
