The Journal of Environmentally Compatible Air Transport System (JECATS) is a not-for-profit international scientific journal dedicated to the publication and public discussion of aspects of the air transport system with a focus on the environmental implications. JECATS publishes original research and review articles that especially, but not solely, combine areas of aerospace engineering, fuels, environmental analysis, climate change, economics, aviation climate mitigation, circularity, and policy analysis. It includes aviation transport related aspects and environmental effects from local to global scales.

07 May 2026 Temporary unavailability of article and preprint PDFs due to technical issues

Since Tuesday, 5 May, 06:30 CET, we have been experiencing technical issues caused by high demand on our systems, which have significantly affected our journal libraries. To maintain platform stability and ensure continued access to critical services, all preprint and journal article PDFs were temporarily restricted, while HTML full-text content and XML files remained available. Since Thursday, 7 May, 08:30 CET, we have made the preprint PDFs available again; however, journal article PDFs remain restricted until the technical issues have been resolved. We apologize for the inconvenience and appreciate your patience as we work to restore full PDF access as quickly as possible. Thank you for your understanding.
