PLANS DISPLAY− A display available in URET
that provides detailed flight plan and predicted
conflict information in textual format for requested
Current Plans and all Trial Plans.
(See USER REQUEST EVALUATION TOOL.)
POINT OUT−
(See RADAR POINT OUT.)
Pilot/Controller Glossary 8/5/04
PCG P−2
POINT−TO−POINT (PTP)− A level of NRR service
for aircraft that is based on traditional waypoints in
their FMSs or RNAV equipage.
POLAR TRACK STRUCTURE− A system of
organized routes between Iceland and Alaska which
overlie Canadian MNPS Airspace.
POSITION AND HOLD− Used by ATC to inform a
pilot to taxi onto the departure runway in takeoff
position and hold. It is not authorization for takeoff.
It is used when takeoff clearance cannot immediately
be issued because of traffic or other reasons.
(See CLEARED FOR TAKEOFF.)
POSITION REPORT− A report over a known
location as transmitted by an aircraft to ATC.
(Refer to AIM.)
POSITION SYMBOL− A computer-generated indication
shown on a radar display to indicate the
mode of tracking.
POSITIVE CONTROL− The separation of all air
traffic within designated airspace by air traffic
control.
PRACTICE INSTRUMENT APPROACH− An
instrument approach procedure conducted by a VFR
or an IFR aircraft for the purpose of pilot training or
proficiency demonstrations.
PREARRANGED COORDINATION− A standardized
procedure which permits an air traffic controller
to enter the airspace assigned to another air traffic
controller without verbal coordination. The procedures
are defined in a facility directive which ensures
standard separation between aircraft.
PREARRANGED COORDINATION PROCEDURES−
A facility’s standardized procedure that
describes the process by which one controller shall
allow an aircraft to penetrate or transit another
controller’s airspace in a manner that assures standard
separation without individual coordination for each
aircraft.
PRECIPITATION− Any or all forms of water
particles (rain, sleet, hail, or snow) that fall from the
atmosphere and reach the surface.
PRECISION APPROACH−
(See PRECISION APPROACH PROCEDURE.)
PRECISION APPROACH PROCEDURE− A standard
instrument approach procedure in which an
electronic 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 equipment
in some ATC facilities operated by the FAA
and/or the military services at joint-use civil/military
locations and separate military installations to detect
and display azimuth, elevation, and range of aircraft
on the final approach course to a runway. This
equipment may be used to monitor certain nonradar
approaches, but is primarily used to conduct a
precision instrument approach (PAR) wherein the
controller issues guidance instructions to the pilot
based on the aircraft’s position in relation to the final
approach course (azimuth), the glidepath (elevation),
and the distance (range) from the touchdown point on
the runway as displayed on the radar scope.
Note: The abbreviation “PAR” is also used to
denote preferential arrival routes in ARTCC
computers.
(See GLIDEPATH.)
(See PAR.)
(See PREFERENTIAL ROUTES.)
(See ICAO term PRECISION APPROACH
RADAR.)
(Refer to AIM.)
PRECISION APPROACH RADAR [ICAO]− Primary
radar equipment used to determine the position
of an aircraft during final approach, in terms of lateral
and vertical deviations relative to a nominal approach
path, and in range relative to touchdown.
Note: Precision approach radars are designed to
enable pilots of aircraft to be given guidance by
radio communication during the final stages of the
approach to land.
PRECISION RUNWAY MONITOR (PRM)− Provides
air traffic controllers with high precision
secondary surveillance data for aircraft on final
approach to parallel runways that have extended
centerlines separated by less than 4,300 feet. High
resolution color monitoring displays (FMA) are
required to present surveillance track data to controllers
along with detailed maps depicting approaches
and no transgression zone.
PREFERENTIAL ROUTES− Preferential routes
(PDRs, PARs, and PDARs) are adapted in ARTCC
computers to accomplish inter/intrafacility controller
coordination and to assure that flight data is posted at
