International security faces an increasingly complex threat environment, and civil aviation, as it plays a significant role in the global economy, is an attractive target for terrorist attacks. Civil aviation is part of the Aerospace Power, and its protection contributes to the State's effort to ensure the sovereignty of its airspace. This book analyzes how Risk Management prioritizes Aviation Security (AVSEC) actions against acts of unlawful interference and proposes mechanisms to strengthen the risk reporting tool. The results indicate that fostering Just Culture improved the identification of risks and provided advantages for senior management, employees, and overall society. The motivation for producing this book lies in the scarcity of works that relate Just Culture, Aviation Security and Aerospace Power. It is intended for students and researchers of all levels (graduation, postgraduation, and professors).
