An Air Defense Identification Zone (ADIZ) is a specific area of airspace, either over land or water, where aircraft must be identified and tracked for national security reasons. This definition comes from the Pilot/Controller Glossary in the Aeronautical Information Manual, which is published by the U.S. Federal Aviation Administration (FAA). In an ADIZ, all aircraft are required to report their location and identity, except for those belonging to the Department of Defense or law enforcement agencies. The regulations regarding the locations of these zones and the flight plan requirements for civilian aircraft can be found in 14 CFR Part 99. Understanding ADIZ is crucial for pilots and aviation professionals, as it ensures safety and security in the skies.
