The operation of unmanned aircraft systems in shared airspace can serve as an accelerator for the global economy and a sensitive addition to the existing mix of transportation modes. For these reasons, concepts of Unmanned Traffic Management have been recently published, defining advanced rules for all potential participants in the operation of unmanned systems. Airspace primarily dedicated to automated unmanned system operations, referred to as U-space in Europe, needs to be designated with consideration for the surrounding airspace. This is especially important in cases where the airspace is controlled, and when declaring U-space airspace, it is necessary to pay particular attention to the density of surrounding air traffic. The goal of this article is to assess the suitability of establishing U-space airspace for Urban Air Mobility in terms of traffic density in a controlled area above the selected metropolis, which is Prague, Czech Republic. To achieve this goal, data on air traffic in the given area were analyzed to obtain precise information about the traffic distribution. Areas in which the establishment of U-space airspace is possible both without implementing dynamic reconfiguration and with the application of the dynamic reconfiguration concept were also selected. The result is the determination of whether it is possible to establish U-space in airspace, as in the analyzed case of the Ruzyne CTR, U-space can be introduced in 83 % of the territory.

Unmanned aircraft systems are growing in popularity with both the general public and private entities. Not only are they expected to be used in the field of small consignment transport, but also for passenger transport. As a result, there is a growing interest in building the overall infrastructure to support the development of the implementation of unmanned aircraft systems into common operations. In this case, we are talking about possible support for the creation of Urban Air Mobility. However, it is not entirely obvious what Urban Air Mobility involves, with which entities it should cooperate or what links will be between the different elements of UAM. The objective of this paper is to create a first high-level model of the analysed environment - Urban Air Mobility - that comprehensively captures all elements and the links between them and can be used for further system analyses of the aviation environment. The result of the research is the model of UAM integrated into the aviation system. Based on this model, the elements that hold roles in the system and without which the UAM could not function are clearly defined and the model could be used for system theory analyses of possible issues in regulation or for setting up processes and rules.

The vast majority of unmanned aircraft systems nowadays rely on satellite navigation to determine their position and altitude. These systems already achieve sufficient accuracy to be used for navigation during flights beyond the visual line of sight of a remote pilot. However, it is necessary to note that these systems are susceptible to reduced signal quality, which can pose a challenge, especially when operating within urban areas. This paper presents the results of experiments that aimed to simulate reduced GNSS signal quality through jamming and spoofing. Both static and dynamic tests were conducted using three specific categories of UAS. Successful jamming of GNSS signals was achieved across all selected UAS categories. The spoofing was successful with only one UAS category.

The passenger satisfaction in civil aviation plays a crucial role in many ways. The airports are business companies with one primary purpose - to generate a profit. This also applies to airlines, handling agents, or cleaning, catering or parking services at the airport. For this purpose it is necessary to maintain a high level of passenger satisfaction as well as a high level of operational efficiency. Maintaining these factors in the required range is important in the entire terminal process and especially at centralised security control checkpoints. One of the essential assumptions for maintaining adequate quality of service is the knowledge of precise estimates of passenger arrival rates. This article describes the principle of passenger arrival rates modelling and deals with factors affecting expected arrival rates.

Since the airports are in fact commercial companies, their main objective is to make profit. Therefore, it is important for the airports to identify the business activities that may increase the income as well as those that may reduce the costs. The terminal process, handling the passengers’ baggage both on their departure and arrival, is a basic process at all airports that are intended for the commercial air transport. The quality of the terminal process provided by the airports has a significant impact on the passengers especially in terms of their satisfaction. In this text, the passenger satisfaction is regarded as a key factor of the terminal process affecting a whole range of other areas. Its high efficiency leads to cost reduction from the perspective of the airport. As it is proposed here, there is a connection between the passenger satisfaction and the process efficiency. For example, the queues that form due to the check-in process may be a result of the imbalance between the passenger arrival rate and the service rate. Therefore, there is a necessity of improving not only the passenger satisfaction but also the process efficiency.
