that requires locating individual photo targets and
navigating to the targets at a preplanned angle and
altitude. The activity normally requires a lateral route
width of 16 NM and altitude range of 1,500 feet to
10,000 feet AGL.
PILOT BRIEFING- A service provided by the FSS
to assist pilots in flight planning. Briefing items may
include weather information, NOTAMS, military
activities, flow control information, and other items
as requested.
(Refer to AIM.)
PILOT IN COMMAND- The pilot responsible for
the operation and safety of an aircraft during flight
time.
(Refer to 14 CFR Part 91.)
PILOT WEATHER REPORT- A report of meteorological
phenomena encountered by aircraft in flight.
(Refer to AIM.)
PILOT'S DISCRETION- When used in conjunction
with altitude assignments, means that ATC has
offered the pilot the option of starting climb or
descent whenever he/she wishes and conducting the
climb or descent at any rate he/she wishes. He/she
may temporarily level off at any intermediate
altitude. However, once he/she has vacated an
altitude, he/she may not return to that altitude.
PIREP-
(See PILOT WEATHER REPORT.)
PITCH POINT- A fix/waypoint that serves as a
transition point from a departure procedure or the low
altitude ground-based navigation structure into the
high altitude waypoint system.
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.)
Pilot/Controller Glossary 2/14/08
PCG P-2
POFZ-
(See PRECISION OBSTACLE FREE ZONE.)
POINT OUT-
(See RADAR POINT OUT.)
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.
PRE-DEPARTURE CLEARANCE- An application
with the Terminal Data Link System (TDLS) that
provides clearance information to subscribers,
through a service provider, in text to the cockpit or
gate printer.
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.
PRECIPITATION RADAR WEATHER DESCRIPTIONS
- Existing radar systems cannot detect
turbulence. However, there is a direct correlation
between the degree of turbulence and other weather
features associated with thunderstorms and the
weather radar precipitation intensity. Controllers will
issue (where capable) precipitation intensity as
observed by radar when using weather and radar
processor (WARP) or NAS ground based digital
radars with weather capabilities. When precipitation
intensity information is not available, the intensity
will be described as UNKNOWN. When intensity
levels can be determined, they shall be described as:
a. LIGHT (< 30 dBZ)
b. MODERATE (30 to 40 dBZ)
c. HEAVY (> 40 to 50 dBZ)
d. EXTREME (> 50 dBZ)
(Refer to AC 00-45, Aviation Weather Services.)
