Pilot/Controller Glossary 8/5/04ATC PREFERRED ROUTES− Preferred routes thatare not automatically applied by Host.ATC REQUESTS− Used to prefix an ATC requestwhen it is relayed to an aircraft by other than an airtraffic controller.ATCAA−(See ATC ASSIGNED AIRSPACE.)ATCRBS−(See RADAR.)ATCSCC−(See AIR TRAFFIC CONTROL SYSTEMCOMMAND CENTER.)ATCT−(See TOWER.)ATIS−(See AUTOMATIC TERMINAL INFORMATIONSERVICE.)ATIS [ICAO]−(See ICAO Term AUTOMATIC TERMINALINFORMATION SERVICE.)ATS ROUTE [ICAO]− A specified route designed forchannelling the flow of traffic as necessary for theprovision of air traffic services.Note: The term “ATS Route” is used to meanvariously, airway, advisory route, controlled oruncontrolled route, arrival or departure, etc.ATTS−(See AUTOMATED TERMINAL TRACKINGSYSTEM.)AUTOLAND APPROACH− An autoland approachis a precision instrument approach to touchdown and,in some cases, through the landing rollout. Anautoland approach is performed by the aircraftautopilot which is receiving position informationand/or steering commands from onboard navigationequipment.Note: Autoland and coupled approaches are flownin VFR and IFR. It is common for carriers to requiretheir crews to fly coupled approaches and autolandapproaches (if certified) when the weatherconditions are less than approximately 4,000 RVR.(See COUPLED APPROACH.)AUTOMATED INFORMATION TRANSFER− Aprecoordinated process, specifically defined in facilitydirectives, during which a transfer of altitudecontrol and/or radar identification is accomplishedwithout verbal coordination between controllersusing information communicated in a full data block.AUTOMATED MUTUAL-ASSISTANCE VESSELRESCUE SYSTEM− A facility which can deliver, ina matter of minutes, a surface picture (SURPIC) ofvessels in the area of a potential or actual search andrescue incident, including their predicted positionsand their characteristics.(See FAAO 7110.65, Para 10−6−4, INFLIGHTCONTINGENCIES.)AUTOMATED PROBLEM DETECTION (APD)−An Automation Processing capability that comparestrajectories in order to predict conflicts.AUTOMATED PROBLEM DETECTIONBOUNDARY (APB)− The adapted distance beyonda facilities boundary defining the airspace withinwhich URET performs conflict detection.(See USER REQUEST EVALUATION TOOL.)AUTOMATED PROBLEM DETECTION IN-HIBITED AREA (APDIA)− Airspace surrounding aterminal area within which APD is inhibited for allflights within that airspace.AUTOMATED RADAR TERMINAL SYSTEMS−The generic term for the ultimate in functionalcapability afforded by several automation systems.Each differs in functional capabilities and equipment.ARTS plus a suffix roman numeral denotes a specificsystem. A following letter indicates a major modificationto that system. In general, an ARTS displaysfor the terminal controller aircraft identification,flight plan data, other flight associated information;e.g., altitude, speed, and aircraft position symbols inconjunction with his/her radar presentation. Normalradar co-exists with the alphanumeric display. Inaddition to enhancing visualization of the air trafficsituation, ARTS facilitate intra/inter-facility transferand coordination of flight information. These capabilitiesare enabled by specially designed computersand subsystems tailored to the radar and communicationsequipments and operational requirements ofeach automated facility. Modular design permitsadoption of improvements in computer software andelectronic technologies as they become availablewhile retaining the characteristics unique to eachsystem.a. ARTS II. A programmable nontracking, computer-aideddisplay subsystem capable of modularexpansion. ARTS II systems provide a level ofautomated air traffic control capability at terminalsPCG A−14
