Sovereignty, Aircraft and Air Navigation The Commentary to the Chicago Convention on International Civil Aviation 1944’

This book provides a systematic and authoritative analysis of Part I of the Chicago Convention, the foundational treaty of international civil aviation. Covering Articles 1–42, the volume examines the legal framework governing State sovereignty over airspace, the international movement and nationality of aircraft, facilitation, conditions of flight, air navigation, and the adoption of international standards. Each provision is analyzed in its historical, doctrinal, institutional and practical context, with reference to International Civil Aviation Organization (ICAO) materials, relevant case law, academic literature, and contemporary State and industry practice. More than eighty years after its adoption, the Chicago Convention continues to structure the international aviation system across 193 Contracting States. Its enduring relevance is increasingly tested by developments including armed conflict, airspace closures, dual registration, cyber interference, public health emergencies, environmental regulation and technological change. Bringing together contributions from leading experts, including perspectives from ICAO, this volume clarifies the scope, operation and continuing significance of the Convention’s air navigation provisions. It is an essential reference for scholars, practitioners, civil aviation authorities, diplomats, regulators and students of international air law.
