PROCEDURE TURN (JCS, NATO) - An aircraft maneuver in which a turn is made away from a designated track followed by a turn in the opposite direction, both turns being executed at a constant rate so as to permit the aircraft to intercept and proceed along the reciprocal of the designated track. PROCEDURE TURN (ICAO) - A maneuver in which a turn is made away from a designated track followed by a turn in the opposite direction to permit the aircraft to intercept and proceed along the reciprocal of the designated track. 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/PT (P/CG) - The maneuver prescribed when it is necessary to reverse direction to establish an aircraft on the intermediate approach segment or final approach course. The outbound course direction of turn, distance within which the turn must be completed, and minimum altitude are specified in the procedure. However, the point at which the turn may be commenced, and the type and rate of turn, are left to the discretion of the pilot. 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 Air Traffic Control as a position report for separation purposes. (See Final Approach Course, Procedure Turn, 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 mean sea level) from cruising altitude/level to interception of a glide slope or to a minimum altitude specified for the initial or intermediate approach segment of a non-precision instrument approach. The profile descent normally terminates at the approach gate or where the glide slope or other appropriate minimum altitude is intercepted. PROGRAMMABLE INDICATOR DATA PROCESSOR/PIDP - The PIDP is a modification to the AN/TPX-42 interrogator systems currently installed in fixed Radar Approach Control's. The PIDP detects, tracks, and predicts secondary radar aircraft targets. These are displayed by means of computer-generated symbols and alphanumeric characters depicting flight identifications, aircraft altitude, ground speed, and flight plan data. Although primary radar targets are not tracked, they are displayed coincident with the secondary radar targets as well as with the other symbols and alphanumerics. The system has the capability of interfacing with Air Route Traffic Control Centers. 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 (P/CG) - (See Special Use Airspace). |
