Note 1: Procedure turns are designated “left” or “right” according to the direction of the initial turn. Note 2: Procedure turns may be designated as being made either in level flight or while descending, according to the circumstances of each individual approach procedure. PROCEDURE TURN INBOUND- That point of a procedure turn maneuver where course reversal has been completed and an aircraft is established inbound on the intermediate approach segment or final approach course. A report of “procedure turn inbound” is normally used by ATC as a position report for separation purposes. (See FINAL APPROACH COURSE.) (See PROCEDURE TURN.) (See SEGMENTS OF AN INSTRUMENT APPROACH PROCEDURE.) PROFILE DESCENT- An uninterrupted descent (except where level flight is required for speed adjustment; e.g., 250 knots at 10,000 feet MSL) from cruising altitude/level to interception of a glideslope or to a minimum altitude specified for the initial or intermediate approach segment of a nonprecision instrument approach. The profile descent normally terminates at the approach gate or where the glideslope or other appropriate minimum altitude is intercepted. PROGRESS REPORT- (See POSITION REPORT.) PROGRESSIVE TAXI- Precise taxi instructions given to a pilot unfamiliar with the airport or issued in stages as the aircraft proceeds along the taxi route. PROHIBITED AREA- (See SPECIAL USE AIRSPACE.) (See ICAO term PROHIBITED AREA.) PROHIBITED AREA [ICAO]- An airspace of defined dimensions, above the land areas or territorial waters of a State, within which the flight of aircraft is prohibited. PROPOSED BOUNDARY CROSSING TIME-Each center has a PBCT parameter for each internal airport. Proposed internal flight plans are transmitted to the adjacent center if the flight time along the proposed route from the departure airport to the center boundary is less than or equal to the value of PBCT or if airport adaptation specifies transmission regardless of PBCT. PROPOSED DEPARTURE TIME- The time that the aircraft expects to become airborne. PROTECTED AIRSPACE- The airspace on either side of an oceanic route/track that is equal to one‐half the lateral separation minimum except where reduction of protected airspace has been authorized. PT- (See PROCEDURE TURN.) PTP- (See POINT-TO-POINT.) PTS- (See POLAR TRACK STRUCTURE.) PUBLISHED ROUTE- A route for which an IFR altitude has been established and published; e.g., Federal Airways, Jet Routes, Area Navigation Routes, Specified Direct Routes. Q Q ROUTE-`Q' is the designator assigned to published RNAV routes used by the United States. |
