TSAS2025: "Towards Sustainable Aviation" Summit

3AF, the French Aerospace Society, presents Towards Sustainable Aviation, an International Summit, held on 28 to 30 January 2025, in Toulouse - France. This conference will address both aircraft design and operations perspectives to prepare and shape a more Efficient Global Air Transport System with the aim to reach carbon neutrality by 2050 for the aviation ecosystem. A more eco-efficient aircraft provides more and more Net Present Value, on one hand, an aircraft which has a significantly improved environmental footprint on the other hand through implementation of new design and technologies, use of drop- in and non-drop-in fuel and potentially new ways of operating aircraft. As a result, the aircraft design must enable to reduce dramatically the operating costs, the cost of ownership, to be sustainable and competitive versus other transportation alternatives, while increasing revenue through cabin services and enhanced aircraft operability. The post-COVID anticipated situation associated to the ambition for carbon-neutral growth for aviation will open a new era for the aviation ecosystem and new opportunities to meet these new challenges. Some emerging technologies or approaches such as the Artificial Intelligence and the digital transformation of the industry, including the intensive use of big data with new business models are key enablers to achieve the objectives of having a more Efficient Global Air Transportation System.
