EXAELIA is impact-driven beyond current European RTD mainstream and address long-range aircraft (~45% of current air transport emissions)
Key Expected Results:
- Promising disruptive aircraft concepts, energy carriers and related technologies that offer more than 50% of CO₂ tailpipe emission reduction by 2050 with respect to 2020.
- Predesigns of modular experimental aircraft for derisking, with new experimentation approaches, as technology infrastructure assets (family concept), for use and re-use.
- Advanced design processes.
- Roadmap for development of the aircraft configurations until TRL 6 / coming 10-20 years, oriented towards EIS 2045-2050, covering next EU FP timeframe. The ultimate benefit will be to accelarate entry into service by one a/c generation (>20 years).
Key stakeholders:
- Aircraft/engine manufacturers and airlines, linked through a strong Advisory Board.
Overall Result capture:
- Business and operational plans for the FTBs.
- Analysis of the holistic impact of the aircraft configurations: climate impact, energy consumption, CO₂ and non-CO₂ emissions.
- Dissemination, training, and wider societal impact (improving public perception).
About Impact Assessment: Science-based informed decisions
Holistic Impact Assessment is an assessment framework carried out using a systematic approach using EC Better regulation guidelines and framework developed by the Impact Monitor and Impact Monitor 2 projects.
There are several metrics evaluated at each level – from Sustainability Index to Noise to Climate effects, further assessing the societal aspects such as skills, workforce and educations sector impacts. The assessment is holistic and presented in an interactive dashboard to understand the interaction of impacts, cross coupling across the multiple levels for each FLRA configuration.
- Sustainability index.
- Climate (CO₂ and Non-CO₂) and Fleet modeling aspects for FLRA configuration.
- Noise levels of the new aircraft concepts.

Sustainability index : one of the important metrics for Impact Assessment, incorporating the five pillars of sustainability (performance, environment, costs, circularity, and social impact)
