Faltin Zsolt, Rohács József, Kavas László — Tue, 15 Apr 2025 00:00:00 +0200

As the applications of UAV/drone developments accelerate, their integration into the entire military and civil aviation is an increasingly important task. At the recommendation of aeronautical research institutes and researchers, the aviation authorities have already created a series of rules and issued instructions to the so-called drone operators with the aim of operating integrated airports safely, efficiently and minimising environmental impact. The presentation deals with the management of the environmental impact of integrated airports. It examines the characteristics of integrated airports, the estimation procedures of the environmental load, the possibilities of reducing the load, the management of the minimisation of the environmental load. The new content of the presentation is the application of the specific, full life cycle calculation procedure of the environmental load in connection with the flight procedures. The results contribute to the development and application of management procedures that reduce environmental impact.

The Evolution of Risk Analysis in Aviation Safety I.

Beller Balázs — Tue, 15 Apr 2025 00:00:00 +0200

As many hazardous operations, aviation also can be carried out along acceptable and unacceptable (would be manageable) risks. The purpose of writing this series of articles is to introduce and review the risk analysis procedures that have emerged since the 1960s, their possible interdependence and their usefulness. The first part of the article series deals basically with the initial steps and linear risk analysis procedures. Describes the risk analysis and visualisation procedures that did not necessarily originate in aviation, but which, when transferred and applied to the field of aviation safety, contribute to enhancing aviation safety. The chosen research method primarily relied on processing domestic and foreign literature from the field of safety and risk assessment.

Methodologies Used in Safety-Critical Development

Schuster György — Tue, 15 Apr 2025 00:00:00 +0200

Ever since we use computers to perform control engineering tasks, our goal has been to ensure that their operational safety meets the desired standards, both from a hardware and software perspective. We can easily see that above a level that is difficult to define that the complexity of the software is so high that it is impossible to see and follow it and, as we wrote in several previous articles, to test it sufficiently. In this paper, after a brief historical summary, we will deal with the development methodologies used today, highlight their appropriate field of application and their main characteristics. We present examples of where and how each discussed methodology can be applied in aviation.

Investigation of the Role of the Human Factor Using Advanced Diagnostic and Information Technology Tools with Special Emphasis on Biomedical Monitoring from the Perspective of Flight Safety

Halmi Lajos — Tue, 15 Apr 2025 00:00:00 +0200

With its long-standing steady growth rate, air transport has become a dominant sector within the transport industries. In addition, airspace has become a major economic resource, whereas until now it was almost exclusively occupied by conventional (piloted) aviation. This is already placing a considerable burden on the professionals working in the field, especially the aircrew. Therefore, it is of paramount importance to have relevant information on the physiological status of pilots and to ensure the technical and aero-medical conditions for monitoring them. Medical recognition of risks and recommendations for their management are very important factors in maintaining overall aviation safety. Research in this area is therefore a priority from both a safety and a technical point of view. The introduction of new technology and testing methods and their application requires further detailed research, backed up by scientific results. These changes present many challenges, but also many opportunities, the mapping and scientific study of which is in the interests of military and national defence, as they can contribute greatly to the achievement of the objectives set by the Defence Forces and, through them, to the information dominance and leadership required in peacetime and beyond.

Possibilities of Air Force Cooperation in the Visegrad Countries

Kesztyűs Viktória — Tue, 15 Apr 2025 00:00:00 +0200

Air force cooperation in the Visegrad Countries is an important and hardly studied field of interest. In my research, I studied previous and actual V4 cooperation, with a focus on defence cooperation. With the help of interviews of professionals from different fields of expertise, I tried to highlight the possibilities for an air force cooperation in the V4. I created summary tables based on open-source information, the main goal of which is to present the current equipment and capabilities of the Czech Republic, Hungary, Poland, and Slovakia. I have also made an attempt to sum up the previous joint military cooperation between the Visegrad Group countries, in order to make predictions for the future.

Safety Challenges for Unmanned eVTOL Aircraft

Terpecz Gábor, Schuster György — Tue, 15 Apr 2025 00:00:00 +0200

In the coming years, with the emergence of smart cities, air mobility (UM), including advanced air mobility (UAM), will be subject to revolutionary changes. With the development of technologies, new aircraft and their new applications have appeared. However, these developments have also brought new security challenges that cannot be addressed safely without them. The future safety challenges of air mobility will be comprehensively examined and, where possible, solutions are presented to ensure that new technologies and services are deployed in a safe and sustainable manner.

The Potential Flight Safety Risks Associated with Unmanned Aerial Vehicles and the Importance of Ensuring their Visibility

Gajdács László — Tue, 15 Apr 2025 00:00:00 +0200

In recent decades, the airspace has become increasingly congested due to the exponential growth in air traffic. Furthermore, the advent of unmanned aerial vehicles (UAVs) has introduced a new dimension to aviation safety. The integration of UAVs into the traditional aviation system presents a multitude of challenges, necessitating the development of appropriate legal regulations, innovative technical solutions, and the implementation of special procedures to mitigate flight safety risks. With the advent of sophisticated systems and equipment, even small UAVs can be effectively monitored and tracked during flight. This enables the immediate and indirect environment surrounding the UAV to be identified, enhancing situational awareness and reducing the risk of collisions. Such solutions include various existing identification systems, such as FLARM,1 OGN,2 ADS-B3 and Remote ID.4 Additionally, special lighting systems on board drones can be employed as a solution, particularly for visual recognition and identification. By utilising these systems, visual surveillance can be extended, and drones can be more easily detected by their surroundings. The simultaneous use of the aforementioned solutions can further enhance the safe integration of drones in traditional traffic [1].

The Development History of Radiolocation and Its Role Nowadays

Major Gábor, Csongor Albert — Tue, 15 Apr 2025 00:00:00 +0200

The discovery and use of radio waves proved to be a huge technological opportunity in the hands of people. This made it possible to accurately determine the location of various radio wave reflective objects. In my study, I would like to examine the process of the development history of this invention, called radar, from the first moment to the present day. Demonstrating the significant role of the military industry during the development of radar systems is one of the important pillars, the other pillar is the constant increase in the safety and efficiency of civil aviation. Even today, these radar systems undergo constant development thanks to the new technological achievements.

Towards Greener Skies: Past Achievements and Future Horizons of Sustainable Aviation Fuels

Mhd Bashar Al Kazzaz, Veress Árpád — Tue, 15 Apr 2025 00:00:00 +0200

Nowadays industries worldwide are transforming to become more climate and environment aware, hence there is a radiant shift of focus and demand toward more green and sustainable solutions which can be easily spotted in various inventions and developments. Aviation is no stranger to these demands if not the most pressurised sector to reduce its environmental footprint, while accommodating the growing demand for air travel. The increased number of funded research in the field of creating new generation and greener aircraft (electrical, hybrid, hydrogen) is the proof of that quest. Pursuing those goals is very important, however, it is safe to say that the industry still has a long way to go. The proposed solutions, while very innovative, lack the resources to provide safe and economical operational flights due to immature technological tools. Therefore, a quick and alternative way was sought after in the meantime, which is what made sustainable aviation fuels (SAF) emerge as a viable option for reducing greenhouse gas emissions and promoting environmental sustainability in aviation. This paper presents a detailed review of SAF’s previous accomplishments and future possibilities and aspects.
