Sustainability is a complex topic. The approach undertook by the sector to transition to a sustainable aviation focuses almost exclusively on technological solutions aiming at reduction of emissions. Though essential, reducing (or even eliminating) emissions is only part of environmental sustainability. The whole topic of sustainability spans over environmental, social and economical considerations. This broad view may be present on some aviation strategic documents, but it is hardly getting the attention (including the funding) it deserves.

This session wants to cover topics which are essential for the transition to sustainability in the air transport system. The session wants to provide a platform for researchers working on aviation sustainability to share their work and participate to a fruitful dialogue. Researchers working on  sustainability aspects out of the mainstream are encouraged to also share their work and contribute with their ideas and views on a better understanding of sustainability in aviation and the way forward to achieving it. The range of topics is broad and includes but is not limited to:

• Sustainability and Impact measurements and assessments, beyond LCA, LCC, and noise;
• Business models (alternative to traditional models, circular business models, etc.);
• Design for sustainability, for circularity, for X and more;

Managing the safe and efficient flow of air traffic requires increased efforts of the aerospace scientific community. ATM remains a bright spot on the innovation chart. There are several questions facing the ATM system and the airports as key components, which this section tries to address: (i) Flight trajectory optimization problems which may improve CO2 and non-CO2 aviation footprint. (ii) At the EASN Conference 2023, one of the key question was why has the number of safety incidents increased, especially runway incursions on busy airports, in spite of the unprecedented levels of aviation safety? In January 2024, the collision on Tokyo Narita Airport confirmed this concern, and validated the use of incidents as a leading indicator to accidents. Engagement of the scientific community to aviation safety is expected to increase, especially in the ATM and Airports segment. How can aviation safety be further improved? (iii) What are the effects of the increasing unlawful interferences with the GNSS signals and other security challenges caused by war on aviation? How resilient is civil aviation to GNSS jamming and spoofing? How could the risks of GNSS outage be mitigated? (iv) How can AI tools be employed to solve ATM and airports problems? (v) Urban mobility and U-space challenges to the traditional ATM: UAV/UAS, and RPAS integration in the airspace. How can urban mobility traffic interfere with the classic VFR and IFR traffic, especially around busy airports?

Targeting minimizing environmental impacts, the sustainability of aviation is facilitated by continual technical developments of innovative solutions and advanced methodologies. Aircraft noise reduction has long been a significant focus in the quest for greener aviation. Despite remarkable technological strides made in addressing aircraft noise pollution, new challenges are anticipated with the growth of air traffic and the emerging adaption to air transportation for increasing urban air mobility (UAM).

This session, Aircraft Noise and Noise Reduction, aims to present and discuss recent scientific and technical developments that enhance our understanding of, and advance the technologies and methods in addressing, aircraft noise generation, propagation and mitigation, as well as the related regulatory framework addressing community noise concerns. It provides a platform for researchers and engineers from academia, research institutes and industries to share their research findings and perspectives on aviation noise and its environmental impacts.

The session covers the following main topics:

• Technologies for aircraft noise control and reduction

Sending humans to space requires a series of technologies that are not necessarily needed for other space missions. A habitat and a Life Support System (LSS) are the first elements required for human survival in space. The design of the habitat should consider among others radiation protection, safety measures and human factors. The LSS will require technologies able to recycle human waste to produce fresh oxygen, water and food for the astronauts. This recycling can be complemented with In-Situ Resources Utilization (ISRU), for missions on the lunar or planetary surfaces. The materials in-situ can also serve as construction materials or to produce fuel for the return vehicle. All these technologies will be crucial for long-term human spaceflight exploration.

The session covers recent developments in hybrid-electric flight, looking at all elements of hybrid electric architectures, i.e. from energy storage, conversion and distribution to electric machines and propulsor arrangements.

Small Air Transport (SAT) is emerging as the most suitable transportation means in order to allow efficient travel over a regional range, in particular for commuters, based on the use of small airports. The vehicles that are comprised under the SAT domain are usually fixed wing aircraft with 5 to 19 seats or similar cargo vehicles, belonging to the EASA CS-23 category. In order to ease the growth of the SAT business domain, the availability of new technological solutions allowing reducing the related operative costs represents a challenge of capital importance. Relevant research activities in this domain are developed in the framework of international programmes, such as, for instance, the European research programme Clean Aviation, where SAT specific projects were carried out. The session, therefore, aims providing the description of the most recent innovations developed in the framework of international research activities addressing the Small Air Transport (SAT) domain, having a look also to sustainability implications in the current and future transport scenarios.

Topics: The topics under the scope of the session cover the whole spectrum of Small Air Transport (SAT) technologies and related concepts, including innovations in cockpit and avionics, propulsion, airframe, materials, air traffic management, self-separation and collision avoidance, mission management, decision making support to the pilot, single pilot operations, sustainability of SAT operations, scenarios, safety regulations and standards. In addition, cross-fertilization among SAT and Urban Air Mobility (UAM) domains is also under the scope of the session, where technologies derived from the UAM applicable to SAT, and vice versa, are of relevant interest.

Technology progress in the field of UAV dedicated electric propulsion we are witness during last decade opened a new promising industry sector. Mobility and transportation related applications are commonly considered as being among most disruptive and innovative – enabling extension of urban ecosystem to the third dimension. But in parallel to the “UAM revolution” there is another one positive disruption on the horizon - smart-city trend. IT/ICT and AI driven change in approach to the key resources we manage as well as cities need to manage every day. What is potential of those two trends if synergized? What will be the smart-UAM, and how will be the impact on potential application areas on sustainability of urban transportation?

Space is recognized as a fundamental resource for making our life on Earth more sustainable. As an example, space-based services and technologies are key in understanding climate change and in the full disaster management. In the past few years, a shift has occurred from a mainly governmental use of the space to a private and commercial use: space tourism, mega-constellations for broadband services, Low Earth Orbit (LEO) constellations for Internet of Things (IoT) services or to improve the navigation services. Terrestrial operators have finally recognized the important role of satellites in the future 6th generation communication networks (6G). However, such evolution has occurred in an uncontrolled and unregulated way thus leading to sustainability challenges both on Earth and in space.

Nowadays space is extremely congested and soon it will no longer be a safe place to provide services. The issue of a sustainable use of space and its protection has become very urgent and requires strong commitments from governments and legislative/political decisions. However, regulatory entities and politician decisions must rely on available technological solutions that could turn the challenge of space sustainability in a real opportunity for the future of space systems and industry. This special session aims to collect contributions that show the current research effort to face this huge and urgent challenge. In particular, we look for contributions on (not limited to):

• impact of future constellations in terms of interference to other systems (communication, astronomy): assessment of the impact/mitigating solutions
• space debris monitoring and management
• technology to enable the use/reuse as more effectively as possible of the deployed space infrastructure through flexible architecture and networking, multi-purpose satellites and interoperable high data rates Inter-Satellite Links (ISLs).
• technology to enable a more efficient use of satellite payload resources to increase lifetime, reliability in the long-term.
• impact of space activities on Earth: assessment/mitigating solutions

The aeronautical and space industries have always been sources of innovation and technological progress. Nowadays, they are of fundamental importance for the development and industrial competitiveness of countries. The design and management of aircraft now follow a systems approach widely recognized in the technical-scientific community. This approach is generating interest and having technological impacts in various other fields and disciplines. These developments have fostered strategic issues such as safety, diagnostics, prognostics, and, more generally, a holistic view of the aerospace system. These issues are now in the spotlight of the scientific community and are attracting growing interest in various industrial sectors such as aerospace, automotive, and automation. Therefore, we believe that a session dedicated to collecting and discussing innovative and promising studies can be of great interest to the technical-scientific community.
