Air Defense Identification Zone

An Air Defense Identification Zone (ADIZ) is a designated area beyond a country's national borders where authorities require aircraft to identify themselves before entering. Its purpose is to provide early warning and prevent potential threats, such as unauthorized or hostile aircraft. Aircraft are asked to report their identity, position, and flight plans when crossing into the ADIZ, allowing the country to monitor and respond appropriately if needed. ADIZs help enhance national security without necessarily implying active defense measures; they are primarily about identification and preparedness beyond a country's immediate airspace.
