AERONAUTICAL INFORMATION PUBLICA-

TION (AIP) [ICAO]− A publication issued by or with

the authority of a State and containing aeronautical

information of a lasting character essential to air

navigation.

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 emer-

gency condition declared by a designated authority.

This condition exists when an attack upon the

continental U.S., Alaska, Canada, or U.S. installa-

tions in Greenland by hostile aircraft or missiles is

considered probable, is imminent, or is taking place.

(Refer to AIM.)

AIR DEFENSE IDENTIFICATION ZONE (ADIZ)−

The area of airspace over land or water, extending

upward from the surface, within which the ready

identification, the location, and the control of aircraft

are required in the interest of national security.

a.

Domestic Air Defense Identification Zone. An

ADIZ within the United States along an international

boundary of the United States.

b.

Coastal Air Defense Identification Zone. An

ADIZ over the coastal waters of the United States.

c.

Distant Early Warning Identification Zone

(DEWIZ). An ADIZ over the coastal waters of the

State of Alaska.

d.

Land−Based Air Defense Identification Zone.

An ADIZ over U.S. metropolitan areas, which is

activated and deactivated as needed, with dimen-

sions, activation dates and other relevant information

disseminated via NOTAM.

Note: ADIZ locations and operating and flight plan

requirements for civil aircraft operations are speci-
fied 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 communica-

tion, 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− 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/as-

sistance services may be provided to VFR aircraft.

(See EN ROUTE AIR TRAFFIC CONTROL

SERVICES.)

(Refer to AIM.)

AIR TAXI− Used to describe a helicopter/VTOL

aircraft movement conducted above the surface but

normally not above 100 feet AGL. The aircraft may

proceed either via hover taxi or flight at speeds more

than 20 knots. The pilot is solely responsible for

selecting a safe airspeed/altitude for the operation

being conducted.

(See HOVER TAXI.)
