The paper is focused on the issue of surveillance systems for air traffic control purposes. The main goal of the work was to process knowledge about the history of surveillance systems and how these systems have evolved over time. For the elaboration of this work, we used professional books, articles and methodologies of various organizations and companies that deal with this topic. Figures and tables have also been used to illustrate the subject more easily. In the first chapter we discuss the history of radiolocation, passive surveillance systems that were used before and after World War II. The first chapter also describes the development of more modern technologies such as ADS-B and multilateration, which have been fully used in the last few years, but their development began much earlier. The second chapter discusses two types of surveillance radars, primary and secondary and their special types. We focused on the description of mainly those specific types that are used at Slovak airports. In the third chapter, we take a closer look at the current development of surveillance systems. We have included in this development the monitoring of air traffic using cameras from remote towers, the combination of surveillance systems into a unit called ARTAS for the purposes of air traffic management and the surveillance of today´s very popular unmanned aerial vehicles.

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.
