This document represents the deliverable D5.2 describing the SESAR solution 0446. These preliminary guidelines aim to support the harmonization between SESAR innovation and EASA certification processes, particularly for solutions involving high levels of automation. The document outlines key gaps and overlaps across selected subprocesses—such as operational concept, safety, security, ethics, and human factors—offering practical insights and methodological steps for alignment. While the guidelines offer a solution at TRL2, they provide a structured foundation for future work and are intended to facilitate more efficient, coherent, and certifiable development of AI-enabled aviation systems.
