(4)
An elliptical pattern consisting of two 180 degree turns.
(5)
A break point at which the first 180 degree turn is started.
(6) The direction of turns.
(7)
Altitude (at least 500 feet above the conventional pattern).
(8)
A “Roll-out” on final approach not less than 1/4 mile from the landing threshold and not less than 300 feet above the ground.
OVERRUN - An area beyond the take-off runway no less wide than the runway and centered upon the extended centerline of the runway, able to support the airplane during an aborted take-off, without causing structural damage to the airplane, and designated by the airport authorities for use in decelerating the airplane during an aborted take-off. (STOPWAY term used for civil airports.)
PAN-PAN (P/CG) - The international radio-telephony urgency signal. When repeated three times indicates uncertainty or alert, followed by nature of urgency. (See MAYDAY)
PAN (JCS) - In air intercept, a code meaning the calling station has a very urgent message to transmit concerning the safety of a ship, aircraft, or other vehicle, or of some person on board or within sight.
PARALLEL INSTRUMENT LANDING SYSTEM/MICROWAVE LANDING SYSTEM 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, Simultaneous Instrument Landing System/Microwave Landing System Approaches)
PARALLEL OFFSET ROUTE - A parallel track to the left or right of the designated or established airway/route. Normally associated with area navigation (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).
PENETRATION (JCS) - That portion of a published High Altitude Terminal Instrument Approach Procedure which prescribes a descent path from the Fix on which the procedure is based to a Fix or altitude from which an approach to the airport is made.
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 (PR) - 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 nautical miles and altitude range of 1,500 feet to 10,000 feet above ground level.
PILOT BRIEFING/PRE-FLIGHT PILOT BRIEFING - A service provided by the Flight Service Stations to assist pilots in flight planning. Briefing items may include weather information, NOTAMS, military activities, flow control information and other items as requested.
