a.I Distribution. Distribution by means of telecommunication. b.II Distribution. Distribution by means other than telecommunications. NOTICE TO AIRMEN. A notice containing information (not known sufficiently in advance to publicize by other means) concerning the PCG N.3 establishment, condition, or change in any compo-nent (facility, service, or procedure of, or hazard in the National Airspace System) the timely knowledge of which is essential to personnel concerned with flight operations. a.NOTAM(D). A NOTAM given (in addition to local dissemination) distant dissemination beyond the area of responsibility of the Flight Service Station. These NOTAMs will be stored and available until canceled. b.NOTAM(L). A NOTAM given local disse-mination by voice and other means, such as telautograph and telephone, to satisfy local user requirements. c.FDC NOTAM. A NOTAM regulatory in nature, transmitted by USNOF and given system wide dissemination. (See ICAO term NOTAM.)NOTICES TO AIRMEN PUBLICATION. A publication issued every 28 days, designed primarily for the pilot, which contains current NOTAM information considered essential to the safety of flight as well as supplemental data to other aeronautical publications. The contraction NTAP is used in NOTAM text. (See NOTICE TO AIRMEN.)NRR. (See NON.RESTRICTIVE ROUTING.)NRS. (See NAVIGATION REFERENCE SYSTEM.)NTAP. (See NOTICES TO AIRMEN PUBLICATION.)NUMEROUS TARGETS VICINITY (LOCA-TION). A traffic advisory issued by ATC to advise pilots that targets on the radar scope are too numerous to issue individually. (See TRAFFIC ADVISORIES.)PCG N.4 O OBSTACLE. An existing object, object of natural growth, or terrain at a fixed geographical location or which may be expected at a fixed location within a prescribed area with reference to which vertical clearance is or must be provided during flight operation. OBSTACLE DEPARTURE PROCEDURE (ODP). A preplanned instrument flight rule (IFR) departure procedure printed for pilot use in textual or graphic form to provide obstruction clearance via the least onerous route from the terminal area to the appropriate en route structure. ODPs are recom-mended for obstruction clearance and may be flown without ATC clearance unless an alternate departure procedure (SID or radar vector) has been specifically assigned by ATC. (See IFR TAKEOFF MINIMUMS AND DEPARTURE PROCEDURES.)(See STANDARD INSTRUMENT DEPARTURES.)(Refer to AIM.)OBSTACLE FREE ZONE. The OFZ is a three dimensional volume of airspace which protects for the transition of aircraft to and from the runway. The OFZ clearing standard precludes taxiing and parked airplanes and object penetrations, except for frangible NAVAID locations that are fixed by function. Additionally, vehicles, equipment, and personnel may be authorized by air traffic control to enter the area using the provisions of FAAO JO 7110.65, Para 3.1.5, VEHICLES/EQUIPMENT/ PERSONNEL ON RUNWAYS. The runway OFZ and when applicable, the inner-approach OFZ, and the inner-transitional OFZ, comprise the OFZ. a. Runway OFZ. The runway OFZ is a defined volume of airspace centered above the runway. The runway OFZ is the airspace above a surface whose elevation at any point is the same as the elevation of the nearest point on the runway centerline. The runway OFZ extends 200 feet beyond each end of the runway. The width is as follows: 1. For runways serving large airplanes, the greater of: (a) 400 feet, or (b) 180 feet, plus the wingspan of the most demanding airplane, plus 20 feet per 1,000 feet of airport elevation. 2. For runways serving only small airplanes: (a)300 feet for precision instrument run-ways. (b)250 feet for other runways serving small airplanes with approach speeds of 50 knots, or more. (c)120 feet for other runways serving small airplanes with approach speeds of less than 50 knots. b.Inner-approach OFZ. The inner-approach OFZ is a defined volume of airspace centered on the approach area. The inner-approach OFZ applies only to runways with an approach lighting system. The inner-approach OFZ begins 200 feet from the runway threshold at the same elevation as the runway threshold and extends 200 feet beyond the last light unit in the approach lighting system. The width of the inner-approach OFZ is the same as the runway OFZ and rises at a slope of 50 (horizontal) to 1 (vertical) from the beginning. c.Inner-transitional OFZ. The inner transitional surface OFZ is a defined volume of airspace along the sides of the runway and inner-approach OFZ and applies only to precision instrument runways. The inner-transitional surface OFZ slopes 3 (horizontal) to 1 (vertical) out from the edges of the runway OFZ and inner-approach OFZ to a height of 150 feet above the established airport elevation. (Refer to AC 150/5300-13, Chapter 3.)(Refer to FAAO JO 7110.65, Para 3.1.5, VEHICLES/EQUIPMENT/PERSONNEL ON RUNWAYS.)OBSTRUCTION. Any object/obstacle exceeding the obstruction standards specified by 14 CFR Part 77, Subpart C. OBSTRUCTION LIGHT. A light or one of a group of lights, usually red or white, frequently mounted on a surface structure or natural terrain to warn pilots of the presence of an obstruction. OCEANIC AIRSPACE. Airspace over the oceans of the world, considered international airspace, where oceanic separation and procedures per the Interna-tional Civil Aviation Organization are applied. Responsibility for the provisions of air traffic control PCG O.1 service in this airspace is delegated to various countries, based generally upon geographic proximi-ty and the availability of the required resources. OCEANIC DISPLAY AND PLANNING SYS-TEM. An automated digital display system which provides flight data processing, conflict probe, and situation display for oceanic air traffic control. OCEANIC NAVIGATIONAL ERROR REPORT. A report filed when an aircraft exiting oceanic airspace has been observed by radar to be off course. ONER reporting parameters and procedures are contained in FAAO 7110.82, Monitoring of Navigational Perfor-mance In Oceanic Areas. |
