    Artificial intelligence and its use in air transport
    (University of Zilina, 2022) Bendík, Dávid; Novák, Andrej
    In recent years, modern technologies have found large applications in sectors such as engineering, healthcare, information technology, robotics, and so forth. One important field in the use of such modern technologies is the field of air transport, where the main objective of using these technologies is to facilitate work for people, make individual tasks more efficient and faster, or reduce the risks associated with human error. In this paper, we will look at artificial intelligence and its use in aviation. Despite the rapid pace of improvement, artificial intelligence is still finding its way to reach its full potential. The history of artificial intelligence dates back to ancient times when many philosophers wondered whether a machine could think. The answer is found in the second half of the 20th century, when, besides theoretical knowledge, we can also observe the first intelligent machines. There is no clear and single correct definition for artificial intelligence, so the subject of the next section is to define artificial intelligence from different sources. The following section details the difference between deep learning and machine learning, comparing their main differences and applications in aviation. The analysis of the current state of application of artificial intelligence in aviation represents the core part of this paper. The emphasis in the analysis is put mainly on applications in the field of airports, air traffic management and safety. In each of these areas, the benefits of using AI are evaluated based on already established AI-enabled technologies. Finally, by analysing the sources available and those applied in our work with the use of a mathematical model, we assess how important the role artificial intelligence currently plays in air transport.

    Electronization of a modern flight school
    (University of Zilina, 2021) Dvorščák, Dávid; Novák, Andrej
    This paper deals with the selection of a specific solution for the electronic management system of the Aviation Training and Educational Center of the University of Žilina in Žilina. The selection is based on an analysis of system properties and research using a pair of questionnaires in which we found out the preferences of instructors and students in flight training. We identified the basic functions and components of the systems and compared them with the research findings. We fulfilled the basic goal of this paper by selecting three systems, that meet the requirements of students, instructors and flight school. The introduction of one of these systems would simplify flight training for students in the future and increase the overall efficiency of the flight school.

    Design of UAV detection system utilizing communication monitoring
    (University of Zilina, 2021) Brodniansky, Martin; Novák, Andrej
    Aim of the paper is to design a system capable of detecting unmanned aerial vehicles utilizing radio communication sensing. The need to detect UAVs is caused by combination of their compact size, sensing capabilities, autonomous nature, ways of misusing them or their spread among unprofessional users unaware of their own risky handling of UAV. All these factors can lead to serious security threats and risk to human lives or infrastructure. In this paper, radio communication detection system is proposed as part of a robust system where radio detection is supplemented by other methods, to maximise probability of UAV detection. Significant attention was dedicated to deeper analysis of current progress in the area of radio communication detection systems as well as acoustic, visual and radar detection. Based on this analysis, all systems were compared together based on probability of detection and distances of detection. Comparation together with different properties of detection methods were basic stepping stone for final system proposal. Robust detection system was successfully designed with radio detection as its primary component, radar detection serving primarily as localizer of UAV, acoustic system serving as backup for detection of UAVs without radio communication and visual system for final confirmation of UAV, its model and presence of camera or load

And in summary, use of these systems in the PBN concept. The next chapter describes the theoretical knowledge that a student should have in flight according to PBN. It describes the theoretical background that a pilot needs to perform such a flight. Every pilot who starts practical flying should have studied the facts given in this chapter. In the third chapter, the reader will learn about the differences between flying a real aircraft and between simulator flying during PBN training. It describes the execution of the flight according to PBN, which is helpful before starting the simulator training. The simulator is an important part of the training and should therefore be given the same level of attention. The last part of this work summarizes the facts from the previous chapters and uses this knowledge in their implementation in flight procedures. When reading this chapter, it is necessary to use your knowledge of practical training. The aim of this work is to create a framework for the future methodological manual for PBN training.

    (University of Zilina, 2021) Sekera, Jakub; Novák, Andrej
    Data communication and management represent a crucial part of future systems in aviation. Huge recent technological advancements have led the whole aeronautical industry into the new evolutionary era called Aviation 4.0. The goal of Aviation 4.0 is the creation of cyber-physical system, following the path from advanced automation, to very first autonomy systems efficiently assisting human. This system involves multiple direct data related applications and devices, including AI analytics, massive use of IoT devices, machine learning capabilities, or advanced monitoring. Due to needed enormous flow of data, current connectivity solutions are becoming insufficient for the future use cases. Near future connectivity problems may become very apparent in datalink. With exponentially increasing amount of data needed by the future aircraft systems, higher datalink communication capacity and better performance of datalink subnetwork are required to meet the higher performance standards and levels of operational safety. This paper offers complex overview of current datalink communication technologies, planned concepts and possible solutions to the problem, in the form of new datalink technology – LEO mega satellite constellation offering Internet connectivity. Through basic deductive research, paper is aimed to study existing datalinks and proposed new LEO satellite communication datalink, evaluating their performance based on the future datalink requirements stated in studied plans and roadmaps. Furthermore, Aviation 4.0 dominant aspects are studied, requirements on future data communication technology are declared, and the possible use cases of Aviation 4.0 smart aircraft systems are showed. The objective of this paper is targeted to determination whether any of the researched datalink subnetwork would comply with Aviation 4.0 future datalink requirements.

    Using SDR receivers for UAV detection
    (University of Zilina, 2021) Dianovský, Robert; Novák, Andrej
    As the number of unmanned aerial vehicles (UAV) increases, new dangers arise for airports and other facilities. Because of this, the need for UAV detection and monitoring in areas, that might be endangered by their operation, is becoming an important topic. Introductory chapters are dedicated to the identification of potential risks posed by UAV operations and research of existing monitoring methods. The main goal of the paper, about which is this article, is to research the possibility of UAV detection by using accessible amateur SDR (Software-Defined Radio) for intercepting radio communications between UAV and its control station. Possible radio detection and localization methods were proposed based on the analysis of radio transmissions used in unmanned aerial systems. A simple theoretical design of SDR-based detection and localization system for monitoring unauthorized UAVs was developed by choosing appropriate methods. The principles and methods used in the design were experimentally demonstrated in several laboratory experiments. Successful realization of this design would possibly improve the availability of drone monitoring systems and reduce their production costs.
