(University of Zilina, 2022) Šulka, Michael; Rostáš, Ján
This aim of the paper is based on a theoretical analysis of possibilities of reducing fuel consumption, emissions and noise during aircraft take-off, taxi and turn-over procedure. In the very beginning, author defines the basic terms of airport infrastructure and defines types of taxiways based on their constructional solution and physical characteristic. Taxiways are not given to the aircrafts as efficient as possible on many airports. To point out the possibility of reducing fuel consumption and emissions production from different taxiway route, author decided to analyse taxiway and runway infrastructure of Vienna-Schwechat Airport (IATA: VIE) and made runway analysis of Airbus A320-200. Another option how to reduce mentioned attributes and increase the quality of environment is single engine taxi (SET) procedure. Author analysed advantages and disadvantages of SET and established possible communication between aircraft crew and air traffic control officer. Push-back tractors produce not negligible amount of pollutants too. The solution is to operate zero emission push-back tractors powered by electric engine or implement innovative system WheelTug into the nose landing gear. These solutions bring many advantages for surrounding environment and reduce airport noise too. Last not but least, author describes advantages and possibilities of use of Fixed Electrical Ground Power instead of APU or GPU during turn-over procedure

VÝCVIK PALUBNÝCH SPRIEVODCOV V KONTEXTE AKTUÁLNEJ BEZPEČNOSTNEJ SITUÁCIE
(Žilinská univerzita v Žiline, 2020) Pajdlhauser, Jakub; Rostáš, Ján
The aim of this paper is to assess and analyse the threats related to unlawful interference to the air transport on which must cabin crew members focus on during training. The paper is discussing about the procedures during security threats and how the cabin crew members should act correctly in connection with illegal acts committed on board the aircraft. The paper analyses and compares the training regulations of the American FAA and the European EASA. Both European and American legislations are based on ICAO regulations, what means that the regulations of those two organizations differ only minimally. In the next part of this paper there is the short enquiry created for employees of an airlines. It was created to determine the satisfaction of cabin crew members with security training and also to identify the deficiency in the security training. By analysing the answers, we found out that quite often there are unruly passengers on board the aircraft. Almost every respondent has experienced such a situation. The main deficiency in the security training is about the practical part. Most respondents would place more emphasis on the duration of practical training for cabin crew members. Another shortage is the lack of training materials for cabin crew members to better understand the issue of security threats. Based on analysis of regulations and evaluation of the enquiry, we suggested new recommendations for the security training of cabin crew. The aim of these recommendations is to improve the security training for cabin crew members and thus positively contribute to increase the level of aviation security.
