Pilot/Controller Glossary 8/5/04POINT−TO−POINT (PTP)− A level of NRR servicefor aircraft that is based on traditional waypoints intheir FMSs or RNAV equipage.POLAR TRACK STRUCTURE− A system oforganized routes between Iceland and Alaska whichoverlie Canadian MNPS Airspace.POSITION AND HOLD− Used by ATC to inform apilot to taxi onto the departure runway in takeoffposition and hold. It is not authorization for takeoff.It is used when takeoff clearance cannot immediatelybe issued because of traffic or other reasons.(See CLEARED FOR TAKEOFF.)POSITION REPORT− A report over a knownlocation as transmitted by an aircraft to ATC.(Refer to AIM.)POSITION SYMBOL− A computer-generated indicationshown on a radar display to indicate themode of tracking.POSITIVE CONTROL− The separation of all airtraffic within designated airspace by air trafficcontrol.PRACTICE INSTRUMENT APPROACH− Aninstrument approach procedure conducted by a VFRor an IFR aircraft for the purpose of pilot training orproficiency demonstrations.PREARRANGED COORDINATION− A standardizedprocedure which permits an air traffic controllerto enter the airspace assigned to another air trafficcontroller without verbal coordination. The proceduresare defined in a facility directive which ensuresstandard separation between aircraft.PREARRANGED COORDINATION PROCE-DURES− A facility’s standardized procedure thatdescribes the process by which one controller shallallow an aircraft to penetrate or transit anothercontroller’s airspace in a manner that assures standardseparation without individual coordination for eachaircraft.PRECIPITATION− Any or all forms of waterparticles (rain, sleet, hail, or snow) that fall from theatmosphere and reach the surface.PRECISION APPROACH−(See PRECISION APPROACH PROCEDURE.)PRECISION APPROACH PROCEDURE− A standardinstrument approach procedure in which anelectronic glideslope/glidepath is provided; e.g., ILS,MLS, and PAR.(See INSTRUMENT LANDING SYSTEM.)(See MICROWAVE LANDING SYSTEM.)(See PRECISION APPROACH RADAR.)PRECISION APPROACH RADAR− Radar equipmentin some ATC facilities operated by the FAAand/or the military services at joint-use civil/militarylocations and separate military installations to detectand display azimuth, elevation, and range of aircrafton the final approach course to a runway. Thisequipment may be used to monitor certain nonradarapproaches, but is primarily used to conduct aprecision instrument approach (PAR) wherein thecontroller issues guidance instructions to the pilotbased on the aircraft’s position in relation to the finalapproach course (azimuth), the glidepath (elevation),and the distance (range) from the touchdown point onthe runway as displayed on the radar scope.Note: The abbreviation “PAR” is also used todenote preferential arrival routes in ARTCCcomputers.(See GLIDEPATH.)(See PAR.)(See PREFERENTIAL ROUTES.)(See ICAO term PRECISION APPROACHRADAR.)(Refer to AIM.)PRECISION APPROACH RADAR [ICAO]− Primaryradar equipment used to determine the positionof an aircraft during final approach, in terms of lateraland vertical deviations relative to a nominal approachpath, and in range relative to touchdown.Note: Precision approach radars are designed toenable pilots of aircraft to be given guidance byradio communication during the final stages of theapproach to land.PRECISION RUNWAY MONITOR (PRM)− Providesair traffic controllers with high precisionsecondary surveillance data for aircraft on finalapproach to parallel runways that have extendedcenterlines separated by less than 4,300 feet. Highresolution color monitoring displays (FMA) arerequired to present surveillance track data to controllersalong with detailed maps depicting approachesand no transgression zone.PREFERENTIAL ROUTES− Preferential routes(PDRs, PARs, and PDARs) are adapted in ARTCCcomputers to accomplish inter/intrafacility controllercoordination and to assure that flight data is posted atPCG P−2
