In this paper, the issue of teaching professional aviation subjects in the field of higher education air transport was ad‐dressed. We present some research results in the field of didactics of professional aviation subjects, teaching effectiveness, motivation and evaluation of students in education. In this work we present some approaches to the development of didactics of professional subjects in Slovakia. We state that the subject of didactics is the student, teacher and knowledge forming the didactic tri‐angle. Didactics of professional subjects examines the possibilities of transforming the knowledge of technical scientific disciplines into the content of education, didactic systems, teaching projects and the studentʹs knowledge. We researched the area of didactics of professional aviation subjects with a focus on motivating students to study. We managed to involve a large sample of students in the research, which helped us in‐crease the objectivity of the results. Based on the research results, we recommend some measures to increase the quality of higher education of students in the field of air transport. The motivating goal for our research is to support the quality of education at the Faculty of Aeronautics of the Technical University of Košice.

The sustainable development concept is promoted as a theoretical frame suitable to face the challenges of the air transport market. The task is to focus on the solutions for current and future air transport strategies to provide movement of people and goods in a sustainable, equal, inclusive and efficient way. This research aims to recognise sustainable development challenges and refer to the situation of Central and Eastern European countries. The challenges to the sustainable development of air transport were grouped into environmental concerns, infrastructural and labour problems, technological change, digitalisation and changing passenger behaviour. Even though Central and Eastern European countries are lagging behind Western countries in terms of the number of passengers carried by air, they face the same challenges to the sustainable development of air transport markets. Air transport companies on their path to sustainable development should search for new, innovative solutions. There is a call for institutional changes to support sustainable initiatives.

The study aims to estimate the air travel demand forecast for domestic passengers' travels in Nigeria from 2002-2016. Data resourced from the Central Bank of Nigeria, the National Bureau of Statistics, and the Federal Airport Authority of Nigeria. The study utilized a multiple regression model using a Stata-Graphic software solver to analyze the data. From the analysis, the result shows that there is a significant relationship between the explanatory variable (passengers) and unexplanatory variables National Disposable Income, Population, Average Airfare, Gross Domestic Product, Exchange Rate, Total Expenditure, and Crude oil price, accounted for adjusted R of 93.624% relationship with demand for domestic air travel of passenger. The R-square statistic shows that the fitted model explains the variability in the number of passengers (NPAX), which is 96.8124%. The Hypothesis testing reveals that National Disposable Income and Airfare have a strong statistically significant relationship with the demand for domestic air travel with a P-value of 0.0013. Mores, a statistically significant relationship exists between National Disposable Income, Average airfare, and Crude oil price with P-values of 0.0017 and 0.0445, respectively. Furthermore, a forecast of the number of passengers and average airfare was carried out using ARIMA (1,0,0) model, which made available the future predicted values for the number of passenger movements and average airfare for the next 10-12 years to come. Thus, the study recommends that stakeholders in the air transport sector should work towards improving the capacity and infrastructure to accommodate the growth of air travel demand for domestic air travel in Nigeria. Policy implications were made on regulating the sector by having a good pricing policy to control the air fare for the industry.

Travel is an inseparable part of human life. It is connected not only with private life but also with business life. People want to travel more, farther and faster. That is why air transport is currently one of the fastest-growing areas of passenger transport, and airlines carry more and more passengers from year to year. Due to the growing negative impact of air transport on the natural environment, research aimed at the development of technologies to reduce the negative impact of air transport is becoming more and more important. One of the possibilities for improving the situation is the use of alternative energy sources, limiting the emission of greenhouse gases into the atmosphere. The paper aimed to analyze the meaningfulness of replacing the classic power unit in a light transport aircraft with a hybrid, combustion-electric power unit. Analyzes were made with the use of simulation methods for the PZL M-28 aircraft.

W Polsce brakuje danych dotyczących zapotrzebowania na energię niezbędną do utrzymania systemów wentylacyjnych, grzewczych i chłodniczych. Duże wartości strumieni powietrza wentylującego, wysokie wymagania dotyczące jakości oraz parametrów cieplno-wilgotnościowych powietrza w obiektach szpitalnych i służby zdrowia wpływają na wysokie koszty ich utrzymania. W dobie kryzysu politycznego, energetycznego oraz globalnie zmieniającego się klimatu, każda metoda ograniczania energii niezbędnej do transportu i uzdatniania powietrza musi być rozważona i uwzględniona zarówno w procesie projektowym, remontowo-modernizacyjnym jak i w codziennej eksploatacji budynków. Celem artykułu było wykazanie w jakim stopniu można ograniczyć roczne zapotrzebowanie na energię określone dla 1 m3/s powietrza zarówno w aspekcie jego transportu jak i uzdatniania. Takie jednostkowe określenie energii jest niezależnym wskaźnikiem, który można wykorzystać do każdej wartości strumienia powietrza wentylującego. Do wyznaczenia rocznego zapotrzebowania na energię niezbędną do uzdatniania powietrza przygotowano wykresy t-tz obrazujące roczny cykl pracy urządzenia wentylacyjnego z odzyskiem ciepła z wymiennikiem o sprawności 50% i 80%. Przyjęto 10 różnych profili sterowania pracą urządzeń. Do wyznaczenia możliwości ograniczenia energii niezbędnej do transportu powietrza wykonano obliczenia dla wentylatorów o mocy właściwej określonej zgodnie z Warunkami Technicznymi. W artykule wykazano, że zapotrzebowanie na energię do uzdatniania powietrza jest ściśle zależne od właściwie przyjętej metody sterowania pracą urządzenia oraz przyjętych wartości temperatury powietrza nawiewanego i/lub w pomieszczeniu. Przedstawiono tu także możliwe scenariusze ograniczenia strumienia powietrza wentylującego w wypadku pomieszczeń nieużytkowanych, w których należy zachować przepływ powietrza przez pomieszczenie. Wskazano także konieczność dostosowania cech architektoniczno-budowlanych budynku do maksymalnego ograniczenia zysków i strat ciepła pomieszczeń.

Poland has no data concerning the energy demand to maintain ventilation, heating, and cooling systems. High values of mechanical ventilation and air-conditioning air flow and high requirements regarding indoor air quality, temperature, and relative humidity in hospital and healthcare facilities result in high maintenance costs. In the time of political and energy crisis and the globally changing climate, any method of reducing the energy demand for transport and air treatment must be considered and included in the design, renovation, and modernisation process as well as in the daily operation of buildings. The aim of the article is to show how to limit the annual energy demand, specified for 1m3/s of airflow volume, both in terms of its transport and treatment. This unitary determination of energy can be an independent indicator that can be used for each value of the ventilation air flow. To determine the annual energy demand for air treatment, t-tz charts were prepared. They show the annual operation cycle of a ventilation unit with heat recovery, with a 50% and 80% efficiency, exchanger. 10 different ventilation system control profiles have been analysed. In order to determine the possibility of reducing the energy demand for air transport, calculations were made for fans with a specific power determined in accordance with the Technical Conditions. The article shows that the energy demand for air heating and cooling is strictly dependent on the properly adopted method of controlling the operation of the device and the assumed values of supply and indoor air temperature. It also presents possible scenarios of limiting the energy demand for air transport with respect to unused rooms, where air flow through the room should be maintained. It was also indicated the need to adjust the architectural and construction features of the building to minimise the heating and cooling loads for the rooms.

The COVID-19 pandemic has affected all areas of our society. The effects of the pandemic on the economy have not only affected mainly the development of transport and tourism but most especially air transport. Many airports in Europe and around the world have experienced a drop in passengers and cargo due to the COVID-19 pandemic. For many airports, this period, which began in 2019, meant huge losses due to a drop in passengers, leading to the collapse of several airlines. Despite the gradually improving situation, the impact of the pandemic is still being felt, and the number of passengers at airports is growing rather slowly. Thus, airports had to deal with the current situation and adapt their future operation to the current conditions. Even the leading airport in Central Europe - the Schwechat Airport in Vienna - was not spared from the effects of the current pandemic. This article aims to evaluate the effects of the COVID-19 pandemic on Schwechat airport. It focuses on the analysis of the development of the airport before and during the pandemic up to the present. Further, this article describes the problems that Schwechat airport dealt with throughout the period, with the loss of passengers, delays and the collapse of carriers. Subsequently, this article is part of a study aimed at identifying the negative effects of the pandemic on air transport and related industries worldwide. Predicting the development of the airport is a very important aspect, especially for the company's management and should be part of the risk management of every company.

The development of measures in civil aviation protection against illegal acts is based on the analysis of incidents, which can be divided into four development stages. Before 9/11, civil aviation entities were mostly reactive; only new threats warranted a proactive approach to mitigating air threats. The present article’s aim was to analyse the development of methods for checking passengers and objects intended for air transport. The analysis of selected incidents, control processes, and the level of security achieved confirm that the implemented security methods and proactive approach to working with air traffic risks are a suitable compromise between passenger comfort, technological development of detection devices, and processes at the airport.

Content available remote Air transport of medical supplies by Preighter aircraft in the Covid-19 pandemic
EN
Air transport plays a significant role in supply chain cargo. It is used for the carriage of dangerous goods e.g., medical supplies. Its role gained particular importance when the Covid-19 pandemic led to a drastic decline in air operations. In response to the crisis, many air carriers temporarily converted passenger aircraft to preighter aircraft. Due to safety regulations, rising freight prices and easing of restrictions on travel, there is a perceived decline in interest in transporting cargo using such a type of aircraft. The aim of the research was to indicate the role of preighter aircraft in the transport of medical supplies in the Covid-19 pandemic. The research problem was formulated in the form of a question: What conditions made preighter aircraft play a leading role in the transport of medical supplies in the Covid-19 pandemic? The publication adopted the following hypotheses: 1. The participation of preighter aircraft in the Covid-19 pandemic depends on the increase in infections. 2. International and European aviation regulations only regulate guidelines for the carriage of cargo using passenger seats. 3. Due to the specific nature of the transport of Covid-19 vaccines, their safe delivery is guaranteed by thermal shipping container. The following research methods have been used in the publication: analysis and synthesis, comparison, search of normative acts and literature on the subject, abstraction, and inference. The authors hope the results obtained from the conducted research and the presented considerations will constitute a starting point for further scientific research on the discussed subject.

Transport lotniczy odgrywa znaczącą rolę w łańcuchu dostaw ładunków. Służy do przewozu towarów niebezpiecznych, np. artykułów medycznych. Jego rola nabrała szczególnego znaczenia, gdy pandemia COVID-19 doprowadziła do drastycznego spadku liczby operacji lotniczych. W odpowiedzi na kryzys wielu przewoźników lotniczych tymczasowo przekształciło samoloty pasażerskie w samoloty preight. Ze względu na przepisy bezpieczeństwa, rosnące ceny frachtu i złagodzenie ograniczeń w podróżowaniu, obserwuje się spadek zainteresowania przewozem ładunków tego typu samolotami.Celem badań było wskazanie roli samolotów preighter w transporcie zaopatrzenia medycznego w pandemii COVID-19. Problem badawczy został sformułowany w formie pytania: jakie warunki sprawiły, że samoloty preight odgrywają wiodącą rolę w transporcie środków medycznych podczas pandemii COVID-19? W publikacji przyjęto następujące hipotezy: 1. Udział samolotów preighter w pandemii COVID-19 zależy od wzrostu infekcji. 2. Międzynarodowe i europejskie przepisy lotnicze regulują jedynie wytyczne dotyczące przewozu ładunków z wykorzystaniem siedzeń pasażerskich. 3. Ze względu na specyfikę transportu szczepionek COVID-19 ich bezpieczną dostawę gwarantuje termiczny kontener transportowy.W publikacji zastosowano następujące metody badawcze: analizę i syntezę, porównanie, wyszukiwanie aktów normatywnych i literatury przedmiotu, abstrakcję i wnioskowanie. Autorzy mają nadzieję, że wyniki uzyskane z przeprowadzonych badań oraz przedstawione rozważania będą stanowić punkt wyjścia do dalszych badań naukowych nad omawianą tematyką.

It is critical to develop a picture of the airlines’ economic and social characteristics to comprehend the growth potential of air transportation. In this context, sustainable reporting is a type of information report that emerges from the enterprises' economic, environmental, and social activities. Especially in recent years, airlines have preferred sustainable reporting to monitor the sustainability levels of their economic, environmental and social performances and to gain a competitive advantage. In this regard, sustainability reports disclose accurate, understandable, and sufficient information, particularly about environmental issues. Despite a boundless amount of literature on airline business models, there is a lack of studies related to the sustainable practices of airlines. One of the academic methods used to measure sustainability performance is the sustainable value-added approach, which provides for the opportunity cost. The project tries to explain the sustainable value-added method in measuring the sustainability performance and also to calculate the sustainable value-added of the first ten airlines in rankings estimated by the IATA report in 2020. This paper examines sustainable value-added results among the top ten airlines. A newly recent approach will be employed, using a content analysis of ten airlines’ documentation including sustainability and annual reports.

The paper presents statistical research results regarding the occurrence of which dangerous aviation events in 1919-2018. The source of the information about the events was the AviationSafetyNetwork website. With the use of Excel 2016 and Statistica v. 12 computer programs, five-time intervals were identified in which hazardous aviation incidents took place.Characterizing the distribution of these events in all periods, due to the technological advancement and capabilities of airplanes, the distribution of dangerous events in the last three periods was compared. The following tests were used to verify the statistical hypotheses: , Shapiro-Wilk, Brown-Forsythe, Kruskal-Wallis. When choosing the appropriate test, the following factors were taken into account: the type of measurement scale, the dependence/independence of samples, and their number. The standard significance level was assumed to be α = 0.05. The consequences and repeatability of aviation events in the identified time intervals were analyzed. The research questions that were posed were the following: in which seasons of the year, months, days of the month, and days of the week did the most dangerous events deaths occur? How often did dangerous events take place? Was the distribution of events similar in the identified periods? The results of the conducted research allowed to identify five periods in which hazardous events took place and demonstrate that in particular periods the distribution of hazardous air events in subsequent seasons, months, and days of the week was not the same.

Aviation is the youngest of the transport industries, yet despite its short history, it is considered one of the most important spheres of transport, both in terms of passenger and cargo transportation. Civil aviation is used by an increasing number of people, and the number of aircraft used by airlines around the world continues to grow. An inherent element that is a particularly important aspect of this mode of transportation is security. In civil aviation, there are numerous dangers associated with events occurring before the flight, during the flight, as well as those associated with the landing process. The events need to be controlled and their causes actively sought and ultimately prevented. The Polish Civil Aviation Authority, as part of the creation of the National Civil Aviation Safety Program, developed the National Safety Plan 2020-2023. The document covers threats identified in the Systemic, European, and National Areas. They are characterized and classified based on the materiality (significance) of the event. The aim of this article is to characterize and analyze selected factors (e.g. collisions with birds, helicopter events) that affect the number of safety incidents in civil aviation. The background of the study was the analysis and synthesis of the literature on the subject, while the main research method was the statistical analysis of historical data on aviation incidents. The data provided in Poland's National Security Plan 2020-2023 were used to distinguish the factors associated with the threats present and synthetically evaluate their impact. The analyses made it possible to identify areas of particular safety risks and form the basis for further detailed research.
