ASSESSMENT OF THE MENTAL STATE OF PILOTS
(Žilinská univerzita v Žiline, 2020) Kandera, Branislav; Chodelka, Frederik; Škvareková, Iveta
The main aim of this article is to define and evaluate current status of the problem, to point out insufficient or even missing mental health examinations of pilots and possible fatal consequences including air accidents caused by pilots’ mental health. According to actual regulations, mental health examinations are being provided only during the first aero-medical examination when applying for first class medical certificate. Today, the mental health is not being evaluated even during the regular examinations for the first class certificate neither for other classes certificates. The mental state of pilots is almost never checked which can mean a real danger for civil aviation. The results of not controlling mental state of pilots might lead to fatal accidents and innocent lives losses. The analysis of air accidents covered in this thesis is based on accidents’ investigations final reports and other relevant sources. Also, the knowledge gained from interviews with experts is applied. Even though the air accidents caused by psychical state of pilots are infrequent, the examinations of pilots’ mental health should not definitely be underrated and neglected.

Danger of icing when operating unmanned aerial vehicles
(University of Žilina, 2022) Ondrejková, Ivana; Kandera, Branislav
The paper examines icing on Unmanned Aerial Vehicles (UAV) during the flight. We chose the Mavic Pro and Mavic 2 Pro UAV by company DJI to carry out the research. Research flights are performed during the early morning hours with meteorological conditions suitable for icing. We use the AirData application to analyse flight data. The aim of the work is to find out how dangerous icing is, what meteorological conditions are suitable for icing, how fast icing is formed during the operation of an unmanned aircraft and how it is possible to suppress or eliminate icing. In introduction of this work elaborated theoretical knowledge about the formation of icing and its types. Subsequently, the negative effects of icing on the flight are described, such as changes in lift, drag, controllability of the aircraft and others. The following section describes the accidents of UAV due to the impact of icing. After analysing the data from the mentioned application, we proposed recommendations for pilots of UAV. Before the flight, we recommend checking the meteorological forecast, focusing on the temperature and humidity at the flight area, usually up to 120 meters above the Earth surface. In-flight recommendations include monitoring rotation speed of propellers and frequent inspection of propellers in meteorological conditions suitable for icing and others.

Development of flight instruments for general aviation aircraft
(University of Zilina, 2022) Ďuricová, Ema; Kandera, Branislav
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.
EFEKTIVITA VÝCVIKU PILOTOV NA DIAĽKU
(Žilinská univerzita v Žiline, 2020) Kandera, Branislav; Škvareková, Iveta; Ažaltovič, Viliam
Although the topic of unmanned aerial vehicles is very acutal, in most cases attention is paid to the safe integration of unmanned aerial vehicles in airspace, their uses and their reliability. But the safe operation of drones is based on the correct and effective training of drone pilots. The paper deals with the training of pilots of unmanned aerial vehicles, defining the scope of training and the possibilities of using UAV simulators for training. An important aspect is the complexity of knowledge about unmanned aerial vehicles, as training is not only a question of control skills, but also of theoretical knowledge of the UAV itself with which the flight is performed. Based on the measured data, it is clear that the simulator plays an important role during the training of piloting unmanned aerial vehicles, while providing a valuable basis for the transition to a type of fixed-wing flight configuration.
Enhancing safety in glider flights
(University of Žilina, 2023) Gánovský, Martin; Kandera, Branislav
The theme of paper is to find out new possibilities in safety improvements during sailplanes flights, focusing primarily on flights when the separation with other traffic is reduced. At the beginning a summary of glider evolution across the centuries is made starting with the interwar period to the shapes that we know from the latest exhibitions. First part of the paper is followed by the analysis of the current available technical measurements which enhance safety and reduce the probability of in-flight collisions during various phases of flight, including latest and most modern technical implementations used by glider operators to enhance the safety of themselves and others. We will also look up for any available legislative rules based both on national civil authority regulations defined by state itself and for regulations that were created by Fédération Aéronautique Internationale (FAI) which covers most of glider competitions organized world-wide. In practical part we followed our thoughts about how to improve the current situation in this part of the aviation industry. In following steps, we decided to ask the glider pilots about their personal experience with reduced separation caused by nearby gliders during different phases of operations. Generally, there is a huge number of mid-air collisions during sailplane competitions and flight phases where pilots are crossing each other by minimal separation (mountain ridge flying). We decided to suggest minor legislative regulations and technical implementations to improve current situation world-wide and make these flights as safe as possible with minimizing of future incidents.
Influence of stress on the performance of pilots in training
(University of Žilina, 2022) Goldschmidt, Jakub; Kandera, Branislav
This paper deals with the influence of stress that affects pilots in training, how stress affects their daily lives, but especially how it affects their concentration and performance during pilot training. It describes what risks, whether mental or physical, can occur to pilots in training. It also discusses about the factors that affect pilots. One of the factors is the kinetosis, to which more attention is paid and which had also become the subject of the research in this diploma thesis. The aim was to use a questionnaire to find out whether the pilots in the training encountered signs of motion sickness during the training, how it affected their concentration and how they dealt with these situations. In conclusion, based on these responses, we suggested possible preventive solutions for other future novice pilots on how to avoid motion sickness and if it had already occured, how it should be eliminated as much as possible not to affect performance and concentration of pilots.

THE MEASUREMENT OF PILOT WORKLOAD
(Žilinská univerzita v Žiline, 2020) Škvareková, Iveta; Ažaltovič, Viliam; Pecho, Pavol; Kandera, Branislav
The article is focused on objective measurement of pilot workload during IFR flight. 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,number of visual intakes, number of saccades, number of blinks, fixations and the durations of these. Our study incorporated overall six pilots divided into two groups: the experienced and inexperienced. The measurements were performed on the ELITE S923 flight simulator located at Žilina airport, Dolný Hričov. Measurement and analysis of the data showed that the pilots showed significant deviations when comparing the two pilot samples. We also demonstrated various scanning techniques during ILS and NDB approaches. The conclusion of our work summarizes the measurement results and the use of eye track technology in the future.

NÁVRH METODIKY VÝCVIKU A UDRŽATEĽNOSTI SCHOPNOSTÍ PILOTÁŽE BEZPILOTNÝCH LIETAJÚCICH PROSTRIEDKOV
(Žilinská univerzita v Žiline, 2020) Ažaltovič, Viliam; Škvareková, Iveta; Kandera, Branislav
While the density of UAVs operations grow in the airspace the demands on their safe operation are increasing. Nowadays, the risk of an unmanned aerial vehicle colliding with an aircraft with another unmanned aerial vehicle or object is high as ever before. It is this ever-increasing danger that is the reason for training remote pilots, who will be able to safely control unmanned aerial vehicles. The goal of this article is to propose a pilot training methodology for the multicopter configuration of UAV. In the future, the proposed methodology may contribute to the development of rules for the training of remote pilots. The proposed methodology can be used in the future as a guide for the safe operation of unmanned aerial vehicles for the general public.
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.
