The paper deals with the maintenance and influencing the human factor in aircraft maintenance. The work is divided into three basic parts. In the first part of the paper, the aim was to describe the maintenance from a historical point of view, to describe the individual stages of maintenance and to summarize how to maintain the years of development. We also have specified individual types of maintenance, maintenance intervals. The most extensive part in the theory are the laws and regulations that must comply with when performing maintenance in the Slovak Republic. This part is indeed included, but we consider it important to mention it in the work. The second part of the paper is the analysis of accidents of commercial aircraft in commercial aviation for the last 3 years. The analysis contains 43 accidents, from which we came to a conclusion. In the first part of the analysis, we selected those accidents that occurred due to maintenance, and then from these accidents, we further determined which accidents occurred due to human error in maintenance. The aim was to determine whether the number of accidents in commercial aviation in civil aviation due to maintenance should increase or decrease, and subsequently, whether the number of accidents in terms of human factor inmaintenance would increase or decrease. The last part so the conclusion is of course focused on the evaluation of the results of the analytical part and the declaration of whether we managed to meet the goal of the paper.
本文论述了飞机维修中的人为因素及其影响因素。这项工作分为三个基本部分。在论文的第一部分,旨在从历史的角度描述维修,描述维修的各个阶段,并总结如何维护多年的发展。我们还指定了个别类型的维护,维护间隔。理论中最广泛的部分是在斯洛伐克共和国进行维修时必须遵守的法律法规。这一部分确实包括在内,但我们认为在工作中提及它很重要。论文的第二部分是对近3年来商用航空中商用飞机事故的分析。分析包含43个事故,从中得出结论。在第一部分的分析中,我们选择了那些由于维修而发生的事故,然后从这些事故中,我们进一步确定哪些事故是由于维修中的人为错误而发生的。目的是确定民用航空中由于维修引起的商业航空事故数量是增加还是减少,随后,维修中人为因素引起的事故数量是增加还是减少。最后一部分,结论当然是集中在分析部分的结果的评估和声明,我们是否设法满足论文的目标。

Data communication and management represent a crucial part of future systems in aviation. Huge recent technological advancements have led the whole aeronautical industry into the new evolutionary era called Aviation 4.0. The goal of Aviation 4.0 is the creation of cyber-physical system, following the path from advanced automation, to very first autonomy systems efficiently assisting human. This system involves multiple direct data related applications and devices, including AI analytics, massive use of IoT devices, machine learning capabilities, or advanced monitoring. Due to needed enormous flow of data, current connectivity solutions are becoming insufficient for the future use cases. Near future connectivity problems may become very apparent in datalink. With exponentially increasing amount of data needed by the future aircraft systems, higher datalink communication capacity and better performance of datalink subnetwork are required to meet the higher performance standards and levels of operational safety. This paper offers complex overview of current datalink communication technologies, planned concepts and possible solutions to the problem, in the form of new datalink technology – LEO mega satellite constellation offering Internet connectivity. Through basic deductive research, paper is aimed to study existing datalinks and proposed new LEO satellite communication datalink, evaluating their performance based on the future datalink requirements stated in studied plans and roadmaps. Furthermore, Aviation 4.0 dominant aspects are studied, requirements on future data communication technology are declared, and the possible use cases of Aviation 4.0 smart aircraft systems are showed. The objective of this paper is targeted to determination whether any of the researched datalink subnetwork would comply with Aviation 4.0 future datalink requirements.
数据通信和管理是未来航空系统的重要组成部分。最近巨大的技术进步将整个航空业带入了一个新的进化时代,即航空4.0。航空4.0的目标是创建信息物理系统,遵循从先进自动化到第一个有效协助人类的自主系统的路径。该系统涉及多个直接与数据相关的应用程序和设备,包括人工智能分析、大量使用物联网设备、机器学习功能或高级监控。由于需要大量的数据流,当前的连接解决方案对于未来的用例来说已经变得不够了。在不久的将来,数据链的连接问题可能会变得非常明显。随着未来飞机系统所需的数据量呈指数级增长,需要更高的数据链通信容量和更好的数据链子网性能,以满足更高的性能标准和运行安全水平。本文提供了当前数据链通信技术的复杂概述,规划的概念和可能的解决方案,以新的数据链技术的形式-提供互联网连接的LEO巨型卫星星座。通过基础的演绎研究,本文旨在研究现有的数据链,并提出新的LEO卫星通信数据链,根据研究计划和路线图中所述的未来数据链需求,评估其性能。进一步研究了航空4.0的主导方面,提出了未来数据通信技术的需求,并展示了航空4.0智能飞机系统可能的用例。本文的目的是确定所研究的数据链子网是否符合航空4.0未来数据链的要求。

International expansion of ground handling service providers at the airports 扩大机场地勤服务供应商的国际规模
Pub Date : 1900-01-01 DOI: 10.26552/pas.z.2021.2.42
Daniel Hluško, A. Tomová
The goal of this paper was to measure and assess the international expansion of independent ground handling providers. Based on the results of individual measurements, we can state that each of the five most important independent providers of groundhandling services selected by us has already undergone a significant international expansion, and thus currently prefers the service of foreign airports to domestic ones. Globalization and the liberalization of the entire aviation sector have largely contributed to this fact, mainly due to the unlocking of market entry and the creation of more favorable conditions on foreign markets. Among the secondary objectives we have included an analysis of the state of the ground handling sector together with an analysis of the European liberalization Directive 96/67 / EC and its impact on the European groundhandling market. The main findings were that for example prices for the provision of ground handling services fell more sharply, while the quality of services increased and the number of providers at airports generally increased, which helped to increase the market share of third-party ground handling providers. The motive for the elaboration of the paper was the outdatedness of previous studies aimed at assessing the international expansion of ground handling service providers. Another motive was the elaboration of a proposal for a measurement method with regard to the performance of providers in foreign markets. The paper presents individual calculations with current input data and classification of providers in terms of the shape of global expansion, taking into account the current ongoing global pandemic Covid-19
本文的目的是衡量和评估独立地勤服务提供商的国际扩张。根据个别测量的结果,我们可以声明,我们选择的五个最重要的独立地勤服务提供商都已经经历了重大的国际扩张,因此目前更喜欢国外机场的服务而不是国内机场。全球化和整个航空部门的自由化在很大程度上促成了这一事实,这主要是由于放开了市场准入和为外国市场创造了更有利的条件。在次要目标中,我们分析了地勤部门的状况,并分析了欧洲自由化指令96/67 / EC及其对欧洲地勤市场的影响。调查的主要结果是,地勤服务的价格下降得更厉害,而服务质量提高了,机场的供应商数量普遍增加了,这有助于增加第三方地勤服务供应商的市场份额。编写这份文件的动机是,以前旨在评估地勤服务提供者的国际扩张的研究已经过时。另一个动机是拟订一项关于供应商在国外市场业绩的衡量方法的建议。考虑到目前正在进行的全球大流行Covid-19,本文根据全球扩张的形状,根据当前输入数据和供应商分类,给出了个人计算

Pub Date : 1900-01-01 DOI: 10.26552/pas.z.2021.2.38
Nikola Sklaličanová, B. Kandera
The paper titled "Unmanned aerial vehicle pilot training" is focused on the analysis of unmanned aerial vehicle pilot training and the importance of using an unmanned flight simulator during the practical training of unmanned aerial vehicle pilots. For the realization of the paper, we used a device that served to measure the mental workload of unmanned aerial vehicle pilots during simulated and practical flight. Our experiment involved 5 unmanned aerial vehicle pilots in training who had zero or minimal flying experience. The aim of this work was to investigate to what extent mental workload acts on UAV pilots during simulated and practical flights. The measurements and their analysis showed that a much greater load is exerted on the pilots of unmanned aerial vehicles during practical flight. Through a primary experiment of already experienced pilots, we concluded that the majority of respondents would welcome the opportunity to use an unmanned flight simulator during their training. The paperconcludes with a summary of the individual measurement results, graphical representations of the respondents' answers, as well as an implementation design that could be applied to the training of UAV pilots.
本文以“无人机飞行员训练”为题,重点分析了无人机飞行员训练,以及在无人机飞行员实训中使用无人飞行模拟器的重要性。为了实现本文,我们使用了一种测量无人机飞行员在模拟和实际飞行过程中心理负荷的装置。我们的实验涉及5名接受训练的无人机飞行员,他们没有或只有很少的飞行经验。这项工作的目的是调查在模拟和实际飞行期间,无人机飞行员的心理工作量在多大程度上起作用。测量结果和分析表明,在实际飞行中,无人机驾驶员承受的载荷要大得多。通过对经验丰富的飞行员的初步实验,我们得出结论,大多数受访者都欢迎在训练期间使用无人驾驶飞行模拟器的机会。本文总结了个人测量结果,受访者回答的图形表示,以及可应用于无人机飞行员培训的实施设计。

Dominik Matula, M. Bugaj
The main goal of the paper is based on the analysis to define the criteria for selecting an aircraft suitable for PPL training. We achieved the main goal by meeting two sub-goals. The first sub-objective is the analysis of training organizations in Slovakia, on the basis of which we have selected entities for the second sub-objective thus the analysis of selected aircrafts suitable for PPL training. In this work we analyze three, most used training aircrafts for PPL training in Slovakia. We analyze selected aircrafts in terms of three main parts, which include, analysis of technical parameters, analysis of flight characteristics and analysis of operating parameters. Based on the given analyzes, we obtained an evaluation of the characteristics of selected aircrafts, their individual advantages and disadvantages. Other results of the work include the evaluation of criteria that are suitable for aircrafts designed for PPL training. This work can be applied in practice, especially when deciding on the selection of a training aircraft for a student or training organization.
本文的主要目标是在分析的基础上确定适合PPL训练的飞机的选择标准。我们通过实现两个次要目标实现了主要目标。第一个分目标是分析斯洛伐克的培训组织,在此基础上,我们为第二个分目标选择了实体,从而分析了适合PPL培训的选定飞机。在这项工作中,我们分析了斯洛伐克PPL训练中最常用的三种训练飞机。我们从技术参数分析、飞行特性分析和运行参数分析三个主要部分对选定的飞机进行了分析。在此基础上,我们对所选飞机的特性、各自的优缺点进行了评价。这项工作的其他结果包括评估适用于为PPL训练而设计的飞机的标准。这项工作可以在实践中应用,特别是在决定为学生或培训组织选择训练飞机时。

Optimisation of turboprop aircraft operations as a means to reduce their environmental footprint 优化涡轮螺旋桨飞机的运行,以减少其环境足迹
Pub Date : 1900-01-01 DOI: 10.26552/pas.z.2021.2.48
Lucia Števárová, Benedikt Badánik
This paper deals with the subject of optimisation of turboprop aircraft operations to decrease their environmental footprint. This aircraft category is not at the forefront of optimisation efforts of operators as it supplies lower volumes of traffic and is equipped with the most fuel-efficient technology for missions served on regional markets. The theoretical part of this paper details turboprop aircraft contributions to global CO2 emissions and analyses aspects behind their efficient performance. Further, it provides a thorough assessment of the operational practices that can significantly reduce the environmental footprint of turboprop aircraft operations. For better illustration, some are exemplified in simple case studies. The practical part of this work aimed to quantify the effects of operational optimisation on turboprop aircraft. Based on the theoretical analysis, we established five operational adjustments whose effects can be determined using performance calculations. These calculations have been carried out using ATR 72-600 aircraft as a reference for a specified average turboprop flight. It was found that through operational adjustments, the fuel consumption on an average ATR 72-600 flight can be decreased on the order of 10%. The energy intensity of operations defined in CO2 per revenue passenger kilometre could be nearly halved compared to actual values of the ATR 72-600 fleet.
本文讨论了涡桨飞机运行优化的主题,以减少其环境足迹。这类飞机并不是运营商优化工作的重点,因为它提供的交通量较低,并且在区域市场上执行任务时配备了最省油的技术。本文的理论部分详细介绍了涡桨飞机对全球二氧化碳排放的贡献,并分析了其高效性能背后的各个方面。此外,它还提供了一个全面的运营实践评估,可以显著减少涡轮螺旋桨飞机运营的环境足迹。为了更好地说明,在简单的案例研究中举例说明了一些。这项工作的实际部分旨在量化操作优化对涡轮螺旋桨飞机的影响。在理论分析的基础上,我们建立了五种操作调整,它们的效果可以通过性能计算来确定。这些计算是使用atr72 -600飞机作为指定平均涡轮螺旋桨飞机飞行的参考进行的。研究发现,通过操作调整,atr72 -600航班的平均燃油消耗量可降低10%左右。与ATR 72-600机队的实际值相比,以每收入乘客公里二氧化碳计算的运营能源强度可以减少近一半。

Implementation of artificial intelligence at airports 在机场实施人工智能
Pub Date : 1900-01-01 DOI: 10.26552/pas.z.2021.2.15
Martin Jágerský, A. Tomová
This paper deals with the trend of implementation artificial intelligence systems at airports, its meaning and impact on the operational performance and functioning of the airports themselves. After summarizing the theoretical knowledge and examining the current state of the problem, there is created a raster of selected crucial operational processes of airports in which artificial intelligence has been implemented so far. The processing of this raster is based primarily on findings of the implementation of AI systems at five selected hub airports. In the paper, there is also examined a status and prospects of the implementation of artificial intelligence in the form of a questionnaire, especially at airports with a smaller number of handled passengers. This paper also discusses the operational and security implications of this implementation, such as faster check-in, easier baggage handling, easier traveling with biometric technologies, improved security controls at airports, improved operational performance with airport robots and more effective elimination of spreading the diseases at airports. The subject of possible economic and sociological consequences is also approached, due to the possible change in the nature of job from the point of view of airport employees and the creation of a certain kind of cooperation between them and artificial intelligence. The conclusions of this paper also include a proposal for a stronger representation of this area in the study program "air transport" with subsequent possible innovation or creation of new school subjects, in order to gain a deeper knowledge to new graduates in this field.
本文讨论了在机场实施人工智能系统的趋势,它的意义和对机场本身的运行性能和功能的影响。在总结了理论知识并检查了问题的现状后,创建了一个选定的机场关键操作流程的栅格,其中人工智能已经实施到目前为止。该栅格的处理主要基于在五个选定的枢纽机场实施人工智能系统的结果。在本文中,还以问卷的形式考察了人工智能的实施现状和前景,特别是在处理乘客数量较少的机场。本文还讨论了这一实施对运营和安全的影响,例如更快的办理登机手续,更容易的行李处理,更方便的生物识别技术旅行,改善机场的安全控制,提高机场机器人的运营绩效,以及更有效地消除机场疾病的传播。从机场员工的角度来看,由于工作性质的可能变化,以及他们与人工智能之间某种合作的产生,也探讨了可能的经济和社会学后果的主题。本文的结论还包括在研究计划“航空运输”中加强这一领域的代表性的建议,随后可能的创新或创建新的学校科目,以便为该领域的新毕业生获得更深入的知识。

After summarizing the theoretical knowledge and examining the current state of the problem, there is created a raster of selected crucial operational processes of airports in which artificial intelligence has been implemented so far. The processing of this raster is based primarily on findings of the implementation of AI systems at five selected hub airports. In the paper, there is also examined a status and prospects of the implementation of artificial intelligence in the form of a questionnaire, especially at airports with a smaller number of handled passengers. This paper also discusses the operational and security implications of this implementation, such as faster check-in, easier baggage handling, easier traveling with biometric technologies, improved security controls at airports, improved operational performance with airport robots and more effective elimination of spreading the diseases at airports. The subject of possible economic and sociological consequences is also approached, due to the possible change in the nature of job from the point of view of airport employees and the creation of a certain kind of cooperation between them and artificial intelligence. The conclusions of this paper also include a proposal for a stronger representation of this area in the study program \"air transport\" with subsequent possible innovation or creation of new school subjects, in order to gain a deeper knowledge to new graduates in this field.","PeriodicalId":142690,"journal":{"name":"Práce a štúdie - Vydanie 10","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132055929","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}

New threats in security 安全新威胁
Pub Date : 1900-01-01 DOI: 10.26552/pas.z.2021.2.20
Natália Kundráthová, Karol Lysina
The article is focused on modern threats in the department of security. The urge to address this issue is due to growing occurrence of unmanned aerial vehicles (UAV) all around the world. The operation of these vehicles is also closely linked to incidents that threaten security, but the most serious are increasing numbers of incidents connected to operation of UAV. For correct processing, it is very important to define the basic concepts and facts related to the topic of UAV. Safety and security in general, are inseparable parts of air transport. Taking into account the constant development of aviation technology, especially in the department of UAV, it is necessary to know the emerging threats and pitfalls associated with the operation of UAV. The following chapters define in more detail the causes of incidents. Later on, we get to know various methods of detection and protection connected to operation of UAV using the comparative method. Key part of our paper is being formed by the analysis of current regulatory framework at European and national level. The result is a proposal for new legislation that could and also should be implemented in national regulations. All things considered, such legislation must meet all attributes necessary for the safe operation of UAV and protection against their illegal use.
这篇文章的重点是安全部门面临的现代威胁。迫切需要解决这一问题是由于无人驾驶飞行器(UAV)在世界各地的日益增加。这些车辆的运行也与威胁安全的事件密切相关,但最严重的是与无人机操作相关的事件越来越多。为了正确处理,明确与无人机主题相关的基本概念和事实是非常重要的。一般来说,安全和安保是航空运输不可分割的一部分。考虑到航空技术的不断发展,特别是在无人机领域,有必要了解与无人机运行相关的新威胁和陷阱。以下各章将更详细地说明事件的起因。随后,我们通过对比的方法了解了与无人机操作相关的各种检测和保护方法。我们论文的关键部分是通过分析当前欧洲和国家层面的监管框架形成的。其结果是提出了一项新的立法建议,可以而且应该在国家法规中加以实施。考虑到所有因素,此类立法必须满足无人机安全操作和防止非法使用所需的所有属性。

Methodology of MCC training in the conditions of the air training and education centre 在航空培训和教育中心的条件下进行MCC培训的方法
Pub Date : 1900-01-01 DOI: 10.26552/pas.z.2021.2.13

The main goal of the paper is to create a methodology for the theoretical and practical part of the multi-crew cooperation training course, which is provided by the Air Training and Education Centre of the University of Žilina since 2007. At the same time, the purpose of the methodology will be to contribute to the quality of education, streamlining the multi-crew cooperation training course and to provide a comprehensive study material for training candidates that reflects on the changes made from 2007 to the present. The reason which stimulated the elaboration of the paper is mainly the already existing study material, published in 2007 within the publication Metodika pilotného výcviku na letovom simulátore, which has now proved to be outdated and insufficient for the needs of the training course. The training material does not reflect the legislative changes made, the modifications to the flight and navigation procedures trainer and some training elements, which are currently emphasized in the training process. The paper, the content of which is a new methodology focused exclusively on the multi-crew cooperation training course, is based on valid and effective regulations, on the airplane flight manual of Beechcraft Super King Air B200 / B200C, inspired by internal operation manuals of the airline operators, internal manuals of the Air Training and Education Centre and is also based on the Metodika pilotného výcviku na letovom simulátore. It will be possible to apply the content of the paper as an up-to-date methodology for theoretical and practical part of the multi-crew cooperation training course, which meets all the currently required criteria. At the same time, it will be possible to implement some parts of the paper into the internal manuals of the Air Training and Education Centre.
本文的主要目标是为多机组合作培训课程的理论和实践部分创建一种方法,该课程自2007年以来由Žilina大学航空培训与教育中心提供。同时,该方法的目的是提高教育质量,简化多船员合作培训课程,并为培训候选人提供综合学习材料,反映2007年至今的变化。激发本文阐述的原因主要是已经存在的研究材料,2007年在Metodika pilotn výcviku na letovom simulátore出版物中发表,现在已被证明是过时的,不足以满足培训课程的需要。训练材料没有反映目前在训练过程中强调的立法修改、飞行和导航程序的修改以及一些训练内容。本文的内容是一种专门针对多机组合作培训课程的新方法,基于有效和有效的法规,基于比奇超级国王航空B200 / B200C的飞机飞行手册,灵感来自航空公司运营商的内部操作手册,航空培训和教育中心的内部手册,也基于Metodika pilotn výcviku na letovom simulátore。将有可能将该文件的内容作为符合目前所有要求标准的多船员合作训练课程的理论和实践部分的最新方法加以应用。同时,将有可能将该文件的某些部分纳入航空培训和教育中心的内部手册。
