Aviation law encompasses the regulations and legal principles governing the operation of aircraft and the management of air travel. Key areas include safety regulations, airworthiness standards, and pilot certification, all overseen by national and international aviation authorities such as the Federal Aviation Administration (FAA) in the United States and the International Civil Aviation Organization (ICAO). These regulations ensure the safe and efficient operation of aircraft, standardize aviation practices, and address environmental concerns. Compliance with these rules is crucial for airlines, manufacturers, and pilots to operate legally and safely.

International air law, a subset of aviation law, focuses on the rules and agreements governing international air travel. It includes treaties such as the Chicago Convention, which established the ICAO and set standards for international air navigation. Key issues addressed by international air law include airspace rights, aviation security, liability in case of accidents, and the resolution of disputes between nations. This legal framework facilitates global connectivity, ensuring that airlines can operate across borders while adhering to agreed-upon standards and procedures, thus promoting safety, efficiency, and cooperation in international air travel.
