Item COLD FRONT AND ITS INFLUENCE ON WEATHER AT AIRPORTS IN WESTERN SLOVAKIA(University of Zilina, 2019) Jarošová, MiriamWeather is limiting factor in planning of our activities. We often have to change our plans to avoid problems that the weather could bring. Transport, especially air transport is very sensitive to sudden changes of weather. For any mode of transport, safety, speed and efficiency is heavily dependent on current and expected weather conditions. Therefore, it is important to know very well the phenomena related to the atmosphere and selected mode of transport.Item COMPETITIVE CHALLENGES FACING THE AIR NAVIGATION SERVICES IN EUROPE(University of Zilina, 2019) Bartoš, Miroslav; Badánik, BenediktEuropean aviation is facing new competitive challenges in a rapidly evolving global market, in particular as a result of a shift of economic growth to the East. These new competitors are benefitting from the rapid economic growth of the entire region, notably Asia, and from aviation becoming a strategic element in their home-country's economic development policies. With an annual growth forecast of 6%, scheduled passenger traffic in the Asia Pacific, the region is likely to grow faster than other regions until 2034 when it will account for 40% of world air traffic. China is expected to become the world’s largest air transport market, overtaking the United States of America in 2023 in terms of number of passengers carried (Sloveniacontrol, 2018).For the EU aviation industry to remain competitive, it is essential that market access is based on a regulatory framework which promotes EU values and standards, enables reciprocal opportunities and prevents distortion of competition. The main challenge for the growth of European aviation is to reduce the capacity and efficiency constraints, which are seriously impeding the European aviation sector's ability to grow sustainably, compete internationally, and which are causing congestion and delays and raising costs. This paper examines competitive environment and performance of seven European Air Navigation Services Providers (ANSP) of Austria, Bosnia and Herzegovina, Croatia, Czech Republic, Hungary, Slovak Republic and Slovenia from European Commission´s target perspective.Item THE ADVANTAGES OF PLANT PROTECTION BY USING UAV OF AIRCRAFT CONFIGURATION AND ULV TECHNOLOGY(University of Zilina, 2019) Yun, Gennadiy; Pederiy, Yuri; Gnashuk, AndreiThe article deals with the design of agricultural UAVs. In recent years, various agricultural UAVs (mainly the copter configuration) have been developed for processing small fields using the method of ultra-low-volume spraying. The proposed project of an agricultural UAV aircraft configuration has several advantages especially when used on large fields. Due to the high flight speed, high payload and the duration of flight time without refuelling, this aircraft has a fairly high performance in the process of protecting plants from diseases and pests. In addition, a relatively simple infrastructure, based on the years of experience in the use of manned aircraft in agriculture, allows, by analogy, to develop an unmanned aviation system for agricultural purposes. Flights are currently underway to test UAV control systems when manoeuvring at low altitudes near obstacles.Item INTEGRATION OF UTM WITHIN THE CURRENT AIRSPACE ARCHITECTURE. IS IT EVEN POSSIBLE?(University of Zilina, 2019) Škultéty, Filip; Poljak, JozefThis paper comprehensively describes the various issues of Unmanned Aircraft Systems (UAS) in terms of their integration into a contemporary and complex system such as Air Traffic Management (ATM). In its introductory part, the paper systematizes and outlines the theoretical knowledge of UAS and categories of airspace sharing entities. However, the main part is devoted to the analysis carried out on the observation of latest proposals of Unmanned Aircraft Systems Traffic Management (UTM), new flight rules as well as state-of-the-art research in several countries throughout the world. The objective of this task is to assess the possibilities, obstacles, and approaches to the integration of unmanned aerial vehicles (UAVs) into the current airspace. The content of this paper is not only informative in nature it but offers concrete explanations, and it may be used as a part of preliminary study for further research in this area.Item MEASUREMENT OF GNSS INTERFERENCE AT AIRPORT ZILINA(University of Zilina, 2019) Kováčik, Ľubomír; Novák, Andrej; Lusiak, TomaszThe paper described the problems of GNSS interference measurement at airport Zilina. The Global navigation satellite systems (GNSS) are widely used both for civilian and military operations to determine the location, speed, acceleration, and trajectory of the user on the ground. GNSS refers to a constellation of satellites that provide signals from space transmitting positioning and timing on data receivers. The intentional errors include jamming and spoofing which are caused by systems sharing the same frequency illegally. The method for measuring signal interference is defined by the parameters that affect the calculation of the position of interest. Monitoring the extent of the interference and its impact is a necessary procedure for the successful management of aircraft operations at the airport.Item AEROjournal - celé číslo 2/2019(University of Zilina, 2019) Kováčik, Ľubomír; Novák, Andrej; Lusiak, Tomasz; Škultéty, Filip; Poljak, Jozef; Yun, Gennadiy; Pederiy, Yuri; Gnashuk, Andrei; Bartoš, Miroslav; Badánik, Benedikt; Jarošová, Miriam; Kazda, Antonín; Bugaj, Martin; Materna, Matúš
