    Possibilities of reducing environmental impacts of aircraft on movement areas and aprons
    (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

    Life cycle assessment of the environmental impacts of transport infrastructure and individual modes of transport
    (University of Zilina, 2021) Kováčiková, Kristína; Kazda, Antonín
    The paper is focused on the assessment of the environmental impacts of transport infrastructure and individual types of transport using the life cycle assessment method. The paper contains a description of the basic terminology of the problem related to transport, the environment and methods of environmental impact assessment. The paper contains analysis on monitoring carbon dioxide emissions from a global perspective as well as from a regional perspective focused on Slovakia. The aim of the paper is to create a proposal for the assessment of environmental impacts of transport infrastructure, in the form of specification of areas of assessment for selected types of transport with a focus on carbon dioxide emissions. Using the knowledge and principles of the life cycle method, a proposal for relevant indicators and a proposal for a comprehensive assessment of the impacts of selected types of transport, focused on carbon dioxide emissions, is created in the paper
