aeronautical data in support of the activities of government, industry, and the aviation community. The
information is published in the National Flight Data Digest.

(See ICAO term AERONAUTICAL INFORMATION PUBLICATION.)

AIR CARRIER DISTRICT OFFICE

 An FAA field office serving an assigned geographical area, staffed with

Flight Standards personnel serving the aviation industry and the general public on matters related to the
certification and operation of scheduled air carriers and other large aircraft operations.

AIR DEFENSE EMERGENCY

 A military emergency condition declared by a designated authority. This

condition exists when an attack upon the continental U.S., Alaska, Canada, or U.S. installations in Greenland
by hostile aircraft or missiles is considered probable, is imminent, or is taking place.

(Refer to AIM.)

AIR DEFENSE IDENTIFICATION ZONE (ADIZ)

 An area of airspace over land or water in which the ready

identification, location, and control of all aircraft (except for Department of Defense and law enforcement
aircraft) is required in the interest of national security.

Note: ADIZ locations and operating and flight plan requirements for civil aircraft operations are specified in

14 CFR Part 99.

(Refer to AIM.)

AIR NAVIGATION FACILITY

 Any facility used in, available for use in, or designed for use in, aid of air

navigation, including landing areas, lights, any apparatus or equipment for disseminating weather information,
for signaling, for radio-directional finding, or for radio or other electrical communication, and any other structure
or mechanism having a similar purpose for guiding or controlling flight in the air or the landing and takeoff of
aircraft.

(See NAVIGATIONAL AID.)

AIR ROUTE SURVEILLANCE RADAR

 Air route traffic control center (ARTCC) radar used primarily to

detect and display an aircraft’s position while en route between terminal areas. The ARSR enables controllers
to provide radar air traffic control service when aircraft are within the ARSR coverage. In some instances, ARSR
may enable an ARTCC to provide terminal radar services similar to but usually more limited than those provided
by a radar approach control.

AIR ROUTE TRAFFIC CONTROL CENTER (ARTCC)

 A facility established to provide air traffic control

service to aircraft operating on IFR flight plans within controlled airspace and principally during the en route
phase of flight. When equipment capabilities and controller workload permit, certain advisory/assistance
services may be provided to VFR aircraft.
