The aviation sector is one of the fastest-growing segments of the transportation industry responsible for a considerable share of greenhouse gas emissions. Therefore, sustainability has become one of the central issues for the aviation sector. International regulatory bodies, airlines, and airport operators, along with aircraft manufacturers and suppliers have put forward initiatives to make aviation green. However, before the wider implementation of new sustainable practices, it is important to look at the opinion of passengers, as customers, on these matters. For this reason, this study aims to explore the knowledge and attitudes of Slovak passengers about green initiatives in aviation. The information about passengers’ knowledge and attitudes was collected through an online questionnaire. The data obtained from 514 respondents were evaluated employing descriptive and inferential statistics. From the results, several conclusions are apparent. Slovak passengers have generally weak environmental knowledge; therefore, it is important to provide them with enough relevant information to make informed decisions. The passengers have generally neutral to positive attitudes towards green initiatives in aviation, with the exception when these initiatives endanger their comfort or finances. For the development of green aviation, it is essential to increase the number of passengers with overall positive attitudes.

English is used in all parts of aviation, especially in aircraft maintenance, where all documentation and various manuals are written in this language. However, there are no formal requirements for aircraft mechanics to have a certain level of English. Nevertheless, aircraft mechanics must master their English language skills, since they are needed for managing their work tasks. This study deals with the issue of insufficiency of standardized English courses, and determines the English language needs of aircraft maintenance in the Slovak Republic, using a triangular approach. The gathered data from 80 respondents for this paper were subjected to descriptive and inferential statistics, which were calculated by the means of Jamovi statistical software. The results revealed that aircraft mechanics engage most often in communication situations that require their knowledge of the reading skill. The importance of all language skills (reading, writing, listening, speaking) is proven by the determination of the most-common communication activities of aircraft mechanics, which should be included in specialized English courses. The results of this study are useful in the creation of language courses which increase the level of English in aircraft maintenance, thus, increasing safety in aviation.

This paper aims to present a comprehensive investigation to obtain the structural calculations needed to design a rigid panel of aluminum alloy for the wing box beam of an ATR 72–500 aircraft. For this design process, several types of materials, including composites like CFRP, are considered so it is possible to compare the actual existing part made of aluminum to them, thus checking the advantages these new materials offer. The research presents an introduction to structural design and provides a study of the relevant literature. The aircraft's principal characteristics and performance abilities were collected so that structural loads can be computed. Research used several methods, a design using conventional methods, applying the theory of elasticity is performed using the Theory of Farrar, allowing us to obtain an analytical solution to the problem, followed by checking the obtained results using Ansys FEM software combined with the parts being designed with CATIA. Furthermore, this same panel is calculated using composite materials instead of conventional aluminum, allowing us to compare both solutions. This research shed light on the intricate process of aircraft structural design, materials selection, and calculation methodologies, highlighting the ongoing pursuit of new and advanced materials. This paper makes clear that using composite materials presents several advantages over traditional ones, allowing for lighter, safer, more fuel-efficient, and more sustainable aircraft. The use of composite materials in the construction of airplane structures is driven by many factors. The results show that the chosen composite materials reduce weight, are durable, have low maintenance requirements, reduce noise, enhance fuel economy, and are resistant to corrosion.
