Air Defense Identification Zone

The North American air defense identification zone (ADIZ) is an area around the territories of the United States and Canada comprising airspace over land or water in which the ready identification, location, and control of civil aircraft is required in the interest of national security. This ADIZ is jointly administered by the civilian air traffic control authorities and the militaries of both nations, under the auspices of the North American Aerospace Defense Command or NORAD. The FAA handles the requests of international aircraft and Transport Canada handles Canadian requests. Any aircraft flying in these zones without authorization may be identified as a threat and treated as an enemy aircraft, potentially leading to interception by fighter aircraft.

An aircraft entering an ADIZ is required to radio its planned course, destination, and any additional details about its trip through the ADIZ to a higher authority, typically an air traffic controller. The aircraft must also be equipped with a radar transponder.

Famous quotes containing the words air, defense and/or zone:

    All things are flowing, even those that seem immovable. The adamant is always passing into smoke. The plants imbibe the materials which they want from the air and the ground. They burn, that is, exhale and decompose their own bodies into the air and earth again. The animal burns, or undergoes the like perpetual consumption. The earth burns, the mountains burn and decompose, slower, but incessantly.
    Ralph Waldo Emerson (1803–1882)

    I would remind you that extremism in the defense of liberty is no vice! And let me remind you also that moderation in the pursuit of justice is no virtue!
    Barry Goldwater (b. 1909)

    Just like those other black holes from outer space, Hollywood is postmodern to this extent: it has no center, only a spreading dead zone of exhaustion, inertia, and brilliant decay.
    Arthur Kroker (b. 1945)
