To conduct the research, models for both the E5 signal and white noise were developed and combined using an additive mixture. Using available data, spectral structures were established for the interference and then integrated into the E5 signal using the Matlab program. The objective of the study was to examine how white noise impacts the spectral power density of the E5 signal. The findings of this research can be utilized in the development of resilient receivers and signal architectures capable of withstanding this kind of disruption.","PeriodicalId":407599,"journal":{"name":"Acta Avionica Journal","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127702326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solutions derived from these technologies, like unmanned aircraft or remote tower operations, on one hand were created in order to generate some sort of a benefit, but on the other hand they led us to a previously uncharted territory, called cybersecurity vulnerabilities. If these vulnerabilities are exploited, they may lead to a massive damage to the Aviation Ecosystem that can contribute to catastrophic failures. With this in mind, protection to the remote tower optical systems is of paramount importance. Therefore, this study focuses on providing a framework for cybersecurity assessments of remote tower optical systems.","PeriodicalId":407599,"journal":{"name":"Acta Avionica Journal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123364954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, materials, procedures, and technologies are developed for the development of such devices to achieve sufficient performance and to be safe for aircrews. The idea of using such air transport for short distances has existed for a long time, and we would like to clarify this issue, as we consider it topical. Some types of light sport aircraft are materially and technologically similar but have different shapes and parameters. Modern technologies are used in production, these flying sports devices have great potential for use not only for sports and recreational purposes but also for transportation between airports, cities, and other countries.","PeriodicalId":407599,"journal":{"name":"Acta Avionica Journal","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132789155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also directly influenced the market valuation of the most important aircraft manufacturers – Boeing and Airbus. Our research shows how investors responded to the spread of the disease and increased market risk. In the case of sudden events, such as serious accidents, investors react immediately, while in the case of the pandemic, despite its global scale, the reaction of investors was delayed, with an impact on the current development of the pandemic in the countries where trading takes place. The risk is thus underestimated at the beginning of the pandemic, which is followed by panic shopping and selling at the moments when the pandemic peaks in the USA and EU. It has also been found that it is not possible to reduce the risk of investment diversification between those companies that react very similarly to the threat of pandemic. Based on the correlation between the trend of share prices of the above aircraft manufacturers and the number of ill people, it can be stated that investors do not effectively take advantage of opportunities to reduce risk and increase returns in this area. The paper also presents further research in the field of the impacts of the pandemic and further global development.","PeriodicalId":407599,"journal":{"name":"Acta Avionica Journal","volume":"461 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120862580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus is centred on the role of knowledge of the language and its effects on safety in aircraft maintenance. The research of literature on human factors in maintenance proved that communication, and thus language, constitute an important part of them. Various models of human factors are presented, and their essence is compared in relation to communication and language. Communication can be done without words, but language is inseparable from communication, every time we use language we communicate. The communication present in aircraft maintenance is necessary for smooth and effective operation and language is used for communicating daily.","PeriodicalId":407599,"journal":{"name":"Acta Avionica Journal","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132211177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they are not effective enough and laser irradiation has become more frequent until the outbreak of the coronavirus epidemic and the decline of aviation. Based on laser illumination statistics in the Czech Republic and an assessment of the danger of lasers at specified distances around airports, a new protective zone was proposed. The protection zones against laser illumination were defined by a rectangle around circles with a radius of 7 NM and the centers on the final approach track.","PeriodicalId":407599,"journal":{"name":"Acta Avionica Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130647295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This forces aerospace manufacturers and users to address questions of a kind in a new way: how to design an ergatic system (ergatic system), how to optimize the coordination or human operator's entry into the \"machine part\", that has a distinctive feature of artificial intelligence. In this article, the properties of the ergatic system are investigated in order to determine the stability of the system in the longitudinal steady-state equilibrium flight mode at 22 965 ft, Mach 0.8, VTAS = 250 m/s. The Control System Toolbox, which is focused on solving tasks related to the analysis and synthesis of linear time - invariant dynamic systems, was used to solve the example.
