ATC SECURITY SERVICES − Communications

and security tracking provided by an ATC facility in

support of the DHS, the DOD, or other Federal

security elements in the interest of national security.

Such security services are only applicable within

designated areas. ATC security services do not

include ATC basic radar services or flight following.
ATC SECURITY SERVICES POSITION − The

position responsible for providing ATC security

services as defined. This position does not provide

ATC, IFR separation, or VFR flight following

services, but is responsible for providing security

services in an area comprising airspace assigned to

one or more ATC operating sectors. This position

may be combined with control positions.
ATC SECURITY TRACKING − The continuous

tracking of aircraft movement by an ATC facility in

support of the DHS, the DOD, or other security

elements for national security using radar (i.e., radar

tracking) or other means (e.g., manual tracking)

without providing basic radar services (including

traffic advisories) or other ATC services not defined

in this section.

ATS ROUTE [ICAO]− A specified route designed for

channelling the flow of traffic as necessary for the

provision of air traffic services.

Note: The term “ATS Route” is used to mean vari-

ously, airway, advisory route, controlled or
uncontrolled route, arrival or departure, etc.

AUTOLAND APPROACH− An autoland approach

is a precision instrument approach to touchdown and,

in some cases, through the landing rollout. An

autoland approach is performed by the aircraft

autopilot which is receiving position information

and/or steering commands from onboard navigation

equipment.

Note: Autoland and coupled approaches are flown

in VFR and IFR. It is common for carriers to require
their crews to fly coupled approaches and autoland
approaches (if certified) when the weather condi-
tions are less than approximately 4,000 RVR.

(See COUPLED APPROACH.)

AUTOMATED INFORMATION TRANSFER−  A

precoordinated process, specifically defined in

facility directives, during which a transfer of altitude

control and/or radar identification is accomplished

without verbal coordination between controllers

using information communicated in a full data block.
AUTOMATED MUTUAL-ASSISTANCE VESSEL

RESCUE SYSTEM− A facility which can deliver, in

a matter of minutes, a surface picture (SURPIC) of

vessels in the area of a potential or actual search and

rescue incident, including their predicted positions

and their characteristics.

AUTOMATED PROBLEM DETECTION (APD)−

An Automation Processing capability that compares

trajectories in order to predict conflicts.
AUTOMATED PROBLEM DETECTION

BOUNDARY (APB)− The adapted distance beyond

a facilities boundary defining the airspace within

which URET performs conflict detection.

(See USER REQUEST EVALUATION TOOL.)

AUTOMATED PROBLEM DETECTION IN-

HIBITED AREA (APDIA)− Airspace surrounding a

terminal area within which APD is inhibited for all

flights within that airspace.
AUTOMATED RADAR TERMINAL SYSTEMS

(ARTS)− A generic term for several tracking systems

included in the Terminal Automation Systems (TAS).

ARTS plus a suffix roman numeral denotes a major

modification to that system.
