Ruch statków powietrznych jest ciągle analizowany z uwagi na problematykę pojemności przestrzeni powietrznej i przepustowości portów lotniczych. Ważnym obszarem jest podejście do lądowania statków powietrznych na dane lotnisko z wykorzystaniem pomocy nawigacyjnych. Urządzenia i systemy nawigacyjne są dostosowywane do wymagań prawnych organizacji europejskich i międzynarodowych. Do użytku operacyjnego podczas podejść do lądowania dopuszczono możliwość korzystania z systemu GNSS wraz z odpowiednią augmentacją (ABAS lub SBAS) określoną jako podejścia RNP APCH. Ich wprowadzenie skutkowało w pojawieniu się szeregu korzyści. Autorzy podjęli się analizy wymagań wyposażenia pokładowego statków powietrznych niezbędnego do wykonywania podejść RNP APCH. Celem naukowym jest ocena wyposażenia pokładowego RNAV statków powietrznych na przykładzie trzech przewoźników lotniczych (stan na grudzień 2018r.). Weryfikacji poddano hipotezę szacując wysoki stopień wyposażenia pokładowego RVAV statków powietrznych. Zastosowano metodę analizy wykorzystując aplikację CNS Dashboard udostępnionej przez Eurocentów. Wskazuje ona zadeklarowane możliwości nawigacyjne samolotów na podstawie planów lotu ICAO przesyłanych przez przewoźników do Network Managera skorelowanych z bazą danych statków powietrznych PRISME Fleet 2. W wyniku przeprowadzonej analizy, można zauważyć, że prawie wszystkie badane statki powietrzne miały wymaganą certyfikację do przeprowadzania podejść RNP APCH z użyciem systemu ABAS (96% badanych). Z drugiej strony żaden z samolotów nie miał wymaganego wyposażenia do wykorzystywania systemu SBAS podczas lądowania. Na podstawie badania dokumentów i obserwacji obszaru badawczego można stwierdzić, że przewoźnicy lotniczy coraz częściej wyposażają swoje statki powietrzne w wymagane moduły podejściach do lądowania typu RNP APCH.

This paper presents an analysis of the impact of conducted and radiated electromagnetic interference affecting the electrical circuits of electronic security systems (ESS) operating over wide areas. The Earth’s electromagnetic environment is heavily distorted by intended and unintended (stationary or non-stationary) sources of radiation. The occurrence of electromagnetic interference in a given environment where an ESS is in use is the cause of damage or malfunction of the entire system or its individual components, e.g., detectors, modules, control panels, etc. In this article, the authors conducted an assessment of the electromagnetic environment where ESS are operated and conducted studies of selected sources of interference. For selected ESS structures, they developed models of the impact of conducted and radiated interference on the process of using these systems in a given environment. For selected technical structures of ESS, the authors of this article developed models of the operation process. They also carried out a computer simulation to determine the impact of natural and artificial electromagnetic interference occurring on the process of using these systems in a given environment over a wide area. The considerations carried out in this article are summarized in the conclusions chapter about the process of using ESS in a distorted electromagnetic environment.

Progressive global warming is triggering the need for immediate action to reduce emissions of carbon dioxide and other aviation-related pollutants. The European Commission is presenting programs indicating the main needs for reducing emissions from the aviation industry. These include the “Fit for 55” project, which talks about the need to achieve climate neutrality for aviation by 2050 and a 55% reduction in CO2 emissions by 2035. Initiatives that could have a real impact on improving the climate situation include the use of sustainable aviation fuels, aircraft improvements that reduce their carbon footprint, and the development of high-speed rail networks in place of short-haul flights. All of these will be crucial for European air transport in the coming decades.The European aviation industry is open to change and is committed to decarbonization in solidarity through the large-scale use of modern and more efficient jet engines and testing aviation fuel blends with environmentally friendly substitutes. Opportunities to increase aviation's environmental friendliness are numerous. One of them is to reduce emissions caused by aircraft taxiing operations on airport grounds. At some of the largest airports, the distances between zones are so great that they require as much as a 25-minute plane ride. This is an environmental nuisance, generating thousands of tons of CO2 each year. Available technological solutions designed to replace conventional aircraft taxiing and reduce emissions were analyzed. Potential solutions were identified that could help airports save up to 85% of annual CO2 emissions. An analysis of environmental trends in aviation showed that investments in counteracting the negative impacts of this mode of transportation will gradually bring aviation closer to achieving climate neutrality. Although this may be difficult in the assumed time horizon, progress in this area is inevitable.

In air traffic, we encounter the problem of airport congestion and limited availability of slots, i.e., time intervals in which air operations are performed. The increase in air traffic intensity, especially at large airports, results in the need to implement modern and effective methods supporting the decision-making process in allocating slots to aircraft. Classic slot allocation methods often do not consider the full spectrum of factors influencing this process, such as the environmental impact of air operations and many other aspects. The article presents the possibility of using the multi-criteria decision support method TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) to optimize the allocation of slots to aircraft. The study's main objective was to develop a model that considers various decision criteria and allows for ranking individual flight operations based on their compliance with the ideal solution model. As part of the research, a literature review was conducted, identifying key criteria from the point of view of airport slot management. The proposed criteria are of significant importance for the process of allocating slots to aircraft. Based on the available data, slots were allocated to aircraft, confirming the practical application of the method. The results of the TOPSIS analysis allowed for the ranking of nine aircraft (S1–S9) according to their compliance with the ideal solution, assuming four decision criteria: fuel consumption, noise emissions, taxiing time, and passenger comfort. The obtained results confirmed that the use of the TOPSIS method allows for a more objective and transparent allocation of slots, taking into account various technical, economic, and environmental aspects. This method allows for dynamic adjustment of the criteria weights depending on the airport's current operational and strategic needs. The TOPSIS method effectively supports the decision-making process in allocating slots to aircraft. Using this method can contribute to increasing the operational efficiency of airports, improving the quality of services for carriers, and the sustainable development of air transport.
