Pilot/Controller Glossary

ATIS [ICAO]-

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
channeling the flow of traffic as necessary for the
provision of air traffic services.

ATS SURVEILLANCE SERVICE [ICAO]" A term
used to indicate a service provided directly by means
of an ATS surveillance system.

Note: The term "ATS Route" is used to mean
variously, airway, advisory route, controlled or
uncontrolled route, arrival or departure, etc.

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.)

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.

(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.

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 INHIBITED AREA (APDIA)- Airspace surrounding a
