Proposal of the FI (S) seminar program for DTO according to the conditions of CAA-ZLP-161
(University of Zilina, 2022) Michálek, Tomáš; Pecho, Pavol
The aim of this paper is to create a proposal for a seminar program for sailplane instructors. Since 2021, new European legislation has come into effect regulating the flight crew licensing. Part of this legislation is the obligation to attend a seminar for each instructor once every 3 years. The seminars can be organized by the declared training organizations (DTO), for which the organization of these seminars is new and have no experience with it, so this program proposal can help them organize the seminar. This research deals with current legislation, analysis of conditions imposed by EASA, analyses the current recommended flight instruction syllabus for new flight instructors together with the syllabus for training new pilots, analyses selected aviation accidents and finally analyses important chapters in aviation medicine.

UAV systémy v procesu sbírání údajů pro využití ve vodním hospodářství

Once every few years there is a necessity to measure the transverse profiles of watercourses within the water management of the Slovak Republic. These are particularly important for the creation of 3D models of watercourses, which aresubsequently used to delineate floodplains or as a means of simulating the maximum possible water flow through a given watercourse. However, the current method of data collection for creating these 3D models is very lengthy and inefficient. Thus, this research is concerned with the design of a new method of data collection for the creation of 3D models, specifically using an unmanned aerial system (UAS) consisting of an unmanned aerial vehicle (UAV) and a laser surface scanning technology (LiDAR) device. The objective was to create a 3D model of the crosssectional profile of the selected drainage channel on Rye Island using the proposed UAS, to compare the measured data using an alternative method of measuring the channel bed by technology currently in use (GNSS receiver) and finally to compare the measured data with archival data. Although the proposed UAS measurements showed unquestionable qualities in terms of frequency and speed of data collection, the values measured by the UAS were often inaccurate and did not correspond to reality, mainly due to the high water pollution in one of the monitored areas. For this reason, the proposed method of data collection is particularly suitable for measuring watercourses with a minimum amount of clean water. Unfortunately, there are not many of these watercourses in Slovakia, so this method is not suitable for frequent use in the conditions of water management in the Slovak Republic.
VLIV SEMIAKTIVNÍHO ŘÍZENÍ TLUMIČŮ VRTIVÝCH POHYBŮ NA KRITICKOU RYCHLOST ŽELEZNIČNÍHO VOZIDLA

S rozvojem vysokorychlostního železničního systému roste rychlost železničních vozidel, s čímž rostou i požadavky na tato vozidla. Nutnou podmínkou zvyšování rychlosti je přitom zachování stability jízdy vozidla. Při vysoké rychlosti totiž může za určitých podmínek dojít k nestabilnímu chodu, který spočívá v nadměrném rozvinutí samobuzeného příčného kmitání dvojkolí ve volném kanálu koleje s negativními důsledky na silové působení vozidla na kolej, na bezpečnost jízdy i na jízdní komfort.
