(See INSTRUMENT LANDING SYSTEM.)(See MARKER BEACON.)(Refer to AIM.)OVER. My transmission is ended; I expect a response. OVERHEAD MANEUVER. A series of predeter-mined maneuvers prescribed for aircraft (often in formation) for entry into the visual flight rules (VFR) traffic pattern and to proceed to a landing. An overhead maneuver is not an instrument flight rules (IFR) approach procedure. An aircraft executing an overhead maneuver is considered VFR and the IFR flight plan is cancelled when the aircraft reaches the “initial point” on the initial approach portion of the maneuver. The pattern usually specifies the following: a.The radio contact required of the pilot. b.The speed to be maintained. c.An initial approach 3 to 5 miles in length. d.An elliptical pattern consisting of two 180 degree turns. e.A break point at which the first 180 degree turn is started. f.The direction of turns. g.Altitude (at least 500 feet above the convention-al pattern). PCG O.3 Pilot/Controller Glossary 2/11/10 h. A “Roll-out” on final approach not less than 1/4 OVERLYING CENTER. The ARTCC facility that mile from the landing threshold and not less than 300 is responsible for arrival/departure operations at a feet above the ground. specific terminal. PCG O.4 P P TIME. (See PROPOSED DEPARTURE TIME.)P-ACP. (See PREARRANGED COORDINATION PROCEDURES.)PAN-PAN. The international radio-telephony urgen-cy signal. When repeated three times, indicates uncertainty or alert followed by the nature of the urgency. (See MAYDAY.)(Refer to AIM.)PAR. (See PRECISION APPROACH RADAR.)PAR [ICAO]. (See ICAO Term PRECISION APPROACH RADAR.)PARALLEL ILS APPROACHES. Approaches to parallel runways by IFR aircraft which, when established inbound toward the airport on the adjacent final approach courses, are radar-separated by at least 2 miles. (See FINAL APPROACH COURSE.)(See SIMULTANEOUS ILS APPROACHES.)PARALLEL MLS APPROACHES. (See PARALLEL ILS APPROACHES.)PARALLEL OFFSET ROUTE. A parallel track to the left or right of the designated or established airway/route. Normally associated with Area Navi-gation (RNAV) operations. (See AREA NAVIGATION.)PARALLEL RUNWAYS. Two or more runways at the same airport whose centerlines are parallel. In addition to runway number, parallel runways are designated as L (left) and R (right) or, if three parallel runways exist, L (left), C (center), and R (right). PBCT. (See PROPOSED BOUNDARY CROSSING TIME.)PBN (See ICAO Term PERFORMANCE.BASED NAVIGATION.)PDC. (See PRE.DEPARTURE CLEARANCE.)PERFORMANCE.BASED NAVIGATION (PBN) [ICAO]. Area navigation based on performance requirements for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace. Note: Performance requirements are expressed in navigation specifications (RNAV specification, RNP specification) in terms of accuracy, integrity, continuity, availability, and functionality needed for the proposed operation in the context of a particular airspace concept. PERMANENT ECHO. Radar signals reflected from fixed objects on the earth’s surface; e.g., buildings, towers, terrain. Permanent echoes are distinguished from “ground clutter” by being definable locations rather than large areas. Under certain conditions they may be used to check radar alignment. PHOTO RECONNAISSANCE. Military activity 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 meteoro-logical phenomena encountered by aircraft in flight. (Refer to AIM.)PILOT’S DISCRETION. When used in conjunc-tion 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 PCG P.1 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.)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.) |
