The division of meteorology is an integral part of aviation that informs about meteorological phenomena and defines their nature. This article focuses on the types of meteorological conditions with which the aircraft comes into contact during the flight, with a closer focus on the take-off and landing phases of the aircraft. The topic of meteorological conditions and their effects was chosen due to the enormous importance of this segment of aviation for the safety and operation of air traffic. The paper has a theoretical character and approaches the connection between individual meteorological conditions and their effect on the behavior of the aircraft. For air safety, a proper interpretation and subsequent adaptation to the corresponding weather events and deviations from standard conditions is essential. The aim of the publication is to define the basic meteorological conditions, weather phenomena and to underline their considerable importance for air traffic. The final part is devoted to the analysis of air accidents during takeoff and landing, which were caused by adverse weather conditions and their underestimation.

The aim of the theme is to examine and clarify the turbulent flow on a larger scale, especially for better flight preparation in the field of turbulence. The work explains the air flow, the formation of turbulent flow and its division into important species. It is solved how the Förchtgott classification is divided according to the type of flow on the leeward side of the mountain obstacle. At the end, it contains information on the written topic. The information is found to be that turbulence is a dangerous weather phenomenon to be taken into account, especially by the pilot so as the turbulence information has been clarified.

The paper deals with the analysis of various smart solutions that can be implemented in airport maintenance. The aim of this paper is to compare the current situation in Slovakia with smart solutions that have been used in the world and to suggest which of the solutions could be implemented in Slovakia. The theoretical part describes the purpose of smart airports and conventional methods of airport maintenance. The next part of the paper is devoted to the description of the current state at the airport in Bratislava and a description of smart solutions used around the world. These may include: scaring birds with drones, snow removal with autonomous ploughs, mowing lawns with robotic mowers, inspection of the Instrumental Landing System ILS with drones and inspection of the Precision Approach Path Indicator PAPI with drones. The last part of the paper compares conventional maintenance methods used at the airport in Bratislava with their smart solutions used around the world. The evaluation includes a proposal for smart solutions which could effectively be used at Bratislava Airport.

The goal of modern society is to improve efficiency in all areas. Our goal is to convert the old engine parts into a functional power unit that is more efficient than the donor parts. Modern electric motors with high efficiency are our main competitors, but our motor has an advantage in a simple design that is easily serviced. We achieve low weight by using lightweight aluminum air-cooled cylinders. In my work, I deal with the fundamentals of two- and four-stroke internal combustion engines. The importance of primary and secondary forces caused by the movement of the crankshaft and pistons is also discussed. Of course, we'll go over how to fill the engine while it's running (carburetor/injection). Following that, I'd like to go over the overall functionality of the drive unit as well as the significance of specific components. In practice, we concentrate on simulating our experimental engine. The purpose of this entire article is to provide the foundational documentation for the subsequent construction of this power unit.

Given the constantly evolving offer proposed for aircraft equipment, the aim of my work is to describe the innovations, that have been implemented in aircraft instruments. The content of the work is divided from the very beginnings of aircraft instruments and their gradual use and expansion. Subsequently, I deal with the data that are displayed by the devices, but also their design and the comparison of the current state compared to the initial versions. Innovations of aircraft instruments are focused on both components and the display of flight data, which leads to simplification of their operation and individual assembly. One of the advantages of modern instruments is their ability to detect errors that may occur during the flight, which serves the pilots to ensure the flight. Furthermore, I focused on the system of collection, processing and evaluation of information, as well as their final production on board the aircraft. My work is mainly focused on the Dynon system, whose functions, display and implementation I described in detail, use and design in aircraft cockpits. The main goal of the thesis is additional processing of information for the subject Aircraft Instruments I and their processing from the student's point of view.

The aim of the paper is to study concepts and types of cloud coverage and clouds itself. It also brings the different types of clouds and its effect on aviation closer to the reader. In the first part paper focuses on general concepts. Then it describes types of clouds and talks about them in detail. Next theme are radars and maps used in aviation to worn and tell us about the cloud coverage as its possible threats. In the last part, the paper shows us some maps and tells us about possible threats caused by clouds or vice versa its positive effects on the flights.

As a result of a tragic accident in Southern Austria, all L-13 “Blanik” sailplanes were grounded. During this accident, the factory structural design failed, even though the plane underwent all mandatory inspections and repairs. The intention of this article is to introduce the possibilities of structural modification of this aircraft, specifically its wing beam and hinge. Already existing modifications are described, as well as new ones with the aim to strengthen its critical parts. Structural modification of the wing hinge and beam, replacement of rivet joints with stronger Hi-Loks and use of different hole angles to ensure a firmer joint and better stress distribution around these holes are covered. Last two beforementioned modifications are described in more detail, a tensile test is carried out and its results are compared to the results of the control samples. In the end, viability and practicability of these modifications are discussed.

The aim of this work is to study current possibilities of monitoring the technical state of the unmanned aircraft from the most basic activities to the more advanced aircraft systems. Partial goal is to create a simple general maintenance checklist for cases when the manufacturer does not publish any maintenance procedures, or the manufacturer is the owner and pilot of the aircraft, in case of DIY aircraft. Theoretical part is devoted to description of most common components of current UAVs and their possible failures and stating current possibilities for maintaining awareness of the technical state of the aircraft prior to, during and after the execution of a flight. Second part will state how to extract the flightlogs and what tools can be used to analyze them. The result of this work is creating general maintenance checklists as well as stating the information about the process of modifying this checklist for the UAV in question. Mentioned checklists will be created for pre-flight, post-flight and regular maintenance check.
