PCG A−14

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 SURVEILLANCE SERVICE [ICAO]– A term

used to indicate a service provided directly by means

of an ATS surveillance system.
ATC SURVEILLANCE SOURCE– Used by ATC

for establishing identification, control and separation

using a target depicted on an air traffic control

facility’s video display that has met the relevant

safety standards for operational use and received

from one, or a combination, of the following

surveillance sources:

a. Radar (See RADAR.)

b. ADS-B (See AUTOMATIC DEPENDENT

SURVEILLANCE−BROADCAST.)

c. WAM (See WIDE AREA MULTILATERATION.)

(See INTERROGATOR.)
(See TRANSPONDER.)
(See ICAO term RADAR.)
(Refer to AIM.)

ATS SURVEILLANCE SYSTEM [ICAO]– A

generic term meaning variously, ADS−B, PSR, SSR

or any comparable ground−based system that enables

the identification of aircraft.

Note: A comparable ground−based system is one

that has been demonstrated, by comparative

assessment or other methodology, to have a level

of safety and performance equal to or better than

monopulse SSR.

ATS ROUTE [ICAO]− A specified route designed for

channeling the flow of traffic as necessary for the

provision of air traffic services.

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

variously, airway, advisory route, controlled or

uncontrolled route, arrival or departure, etc.

ATTENTION ALL USERS PAGE (AAUP)- The

AAUP provides the pilot with additional information

relative to conducting a specific operation, for

example, PRM approaches and RNAV departures.
AUTOLAND APPROACH−An autoland system

aids by providing control of aircraft systems during

a precision instrument approach to at least decision

altitude and possibly all the way to touchdown, as

well as in some cases, through the landing rollout.

The autoland system is a sub-system of the autopilot

system from which control surface management

occurs. The aircraft autopilot sends instructions to the

autoland system and monitors the autoland system

performance and integrity during its execution.
AUTOMATED INFORMATION TRANSFER

(AIT)− 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.

(See FAA Order JO 7110.65, Para 10−6−4,

INFLIGHT CONTINGENCIES.)

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 EDST performs conflict detection.

(See EN ROUTE DECISION SUPPORT TOOL.)

AUTOMATED PROBLEM DETECTION INHIB-

ITED AREA (APDIA)− Airspace surrounding a
