    Study of reinforcement design h-profile of aircraft wing spar
    (University of Zilina, 2020) Pecho, Pavol; Magdolenová, Paulína; Hrúz, Michal; Kováčik, Pavel; Škvareková, Iveta
    In today's world, with ever-increasing safety requirements, there is a growing demand to maintain or reduce production costs. In aviation, in addition to factors like weight and related variables such as resistance to vibration, corrosion, temperature and other are also considered. The task of this paper is to analyse unconventional designs of wing beams with respect to the current requirements of the aviation industry. In the article, the authors analyse the possibilities of design modification either by adding ribs to the profile, or by changing the cross-section of the profile itself. In practice, such design changes would increase weight, production time and finances, but also increase strength and thus safety. All proposed changes were subjected to strength analyses by FEM (Finite element method) computer simulations. The article output is the selection of suitable designs for further observation and experimental verification to ensure comprehensive results for the possibility of implementation in practice. Despite the non-traditional shapes of the proposed wing beam cross-sections, the authors assume that traditional beam shapes will be gradually modified more efficiently.

    New regulations for UAS flights
    (University of Zilina, 2020) Kandera, Branislav; Škultéty, Filip; Badánik, Benedikt
    The paper deals with the legislation in the field of unmanned aircraft systems (UAS) in the Slovak Republic. The main goal of the paper is to analyse the current legislative framework, which sets the basic rules and restrictions. The article’s contribution is a description of the latest Implementing Regulation (EU) 2019/947. The solution to the issue consists of an analysis of the requirements for changes in current legislation based on people’s experience from practice. The reason for the changes is to facilitate flying with UAS for all user groups, provided that safety is maintained, and risks are minimised. These new regulations are causing the most significant changes, especially for organisations that will perform aerial work with the UAS in the Specific category. These organisations need to transform their operations manuals and extend the aerial work system with a risk analysis.

    ANALÝZA RUŠENIA SIGNÁLU GNSS NA LETISKU POPRAD- TATRY
    (Žilinská univerzita v Žiline, 2020) Novák, Andrej; Novák Sedláčková, Alena; Stelmach, Anna
    The paper is focused on the GNSS signal interference during the airport approach procedures at small Slovak regional airport Poprad-Tatry. The paper analyzes the simulation of the situation during the identification and monitoring of GNSS signal interference by ground station situated at the airport. Nowadays is still important to develop air transport and increasing the safety and continuity of provided services even at small regional airports. One of the most appropriate possibilities is to use at this kind of airports with insufficiently equipped navigation infrastructure the GNSS approach. The monitoring of reliability of this system and implementation of monitoring the GNSS signal interference in the final phase of the instrument approach will increase the safety of the flight.

    VPLYV PODSVIETENIA PALUBNÝCH PRÍSTROJOV NA PILOTOV
    (Žilinská univerzita v Žiline, 2020) Škvareková, Iveta; Brezoňáková, Andrea; Kandera, Branislav
    The Flight deck of a modern transport category aircraft is a highly refined, ergonomically; rigorously organised workplace. In such a small area, an extraordinary amount of information is required for the pilot to work, control and monitor the aircraft systems. With technological advances, however, the aircraft has become more and more complex and in some cases over automated. The amount of available information has increased and the limiting factor became how to efficiently display this information. Larger flight instrument displays have replaced conventional, analogue, instruments and can be combined with touch screen efficiency tools. Their ever-increasing size brings with them issues relating to light emissions and eye absorption. This research paper complements the current study and measurement of stress, fatigue and human factors with respect to increasing artificial light intensity experienced by Pilots on the Flight Deck. The authors present the results of several measurements taken using a flight simulator. For the purpose of our research, we decided to use eye monitoring technology to record eye movements to determine the pilot's performance. Eye monitoring provides data on the number of eye movements, fixations and the durations of these. The research results provide Air Operators, Airlines and aeronautical designers with valuable data on human behaviour and the reactions to Flight Deck environmental changes.
