ADIZ meaning in Governmental ?

Answer: What is Air Defense Identification Zone mean?

An air defense identification zone (ADIZ) is airspace over land or water in which the identification, location, and control of civil aircraft is performed in the interest of national security. They may extend beyond a country's territory to give the country more time to respond to possibly hostile aircraft. The concept of an ADIZ is not defined in any international treaty and is not regulated by any international body.

The first ADIZ was established by the United States on December 27, 1950, shortly after President Truman had proclaimed a national emergency during the Korean War. About 20 countries and regions now have such zones including Canada, India, Japan, Pakistan, Bangladesh, Finland, Norway, the United Kingdom, People's Republic of China, South Korea, Taiwan, United States, Sweden, Iceland and Iran. Russia and North Korea have unofficial ADIZs as well. Usually such zones only cover undisputed territory, do not apply to foreign aircraft not intending to enter territorial airspace, and do not overlap.

Air defense zones should not be confused with flight information regions (FIRs), which are used to manage air traffic.
