NO GYRO APPROACH. A radar approach/vector provided in case of a malfunctioning gyro-compass or directional gyro. Instead of providing the pilot with headings to be flown, the controller observes the radar track and issues control instructions “turn right/left” or “stop turn” as appropriate. (Refer to AIM.)NO GYRO VECTOR. (See NO GYRO APPROACH.)NO TRANSGRESSION ZONE (NTZ). The NTZ is a 2,000 foot wide zone, located equidistant between parallel runway final approach courses in which flight is not allowed. NONAPPROACH CONTROL TOWER. Author-izes aircraft to land or takeoff at the airport controlled by the tower or to transit the Class D airspace. The primary function of a nonapproach control tower is the sequencing of aircraft in the traffic pattern and on the landing area. Nonapproach control towers also separate aircraft operating under instrument flight rules clearances from approach controls and centers. They provide ground control services to aircraft, vehicles, personnel, and equipment on the airport movement area. NONCOMMON ROUTE/PORTION. That segment of a North American Route between the inland navigation facility and a designated North American terminal. NONCOMPOSITE SEPARATION. Separation in accordance with minima other than the composite separation minimum specified for the area con-cerned. NONDIRECTIONAL BEACON. An L/MF or UHF radio beacon transmitting nondirectional signals whereby the pilot of an aircraft equipped with direction finding equipment can determine his/her bearing to or from the radio beacon and “home” on or track to or from the station. When the radio beacon is installed in conjunction with the Instrument Landing System marker, it is normally called a Compass Locator. (See AUTOMATIC DIRECTION FINDER.)(See COMPASS LOCATOR.)NONMOVEMENT AREAS. Taxiways and apron (ramp) areas not under the control of air traffic. NONPRECISION APPROACH. (See NONPRECISION APPROACH PROCEDURE.)NONPRECISION APPROACH PROCEDURE. A standard instrument approach procedure in which no electronic glideslope is provided; e.g., VOR, TACAN, NDB, LOC, ASR, LDA, or SDF approaches. NONRADAR. Precedes other terms and generally means without the use of radar, such as: a. Nonradar Approach. Used to describe instru-ment approaches for which course guidance on final PCG N.2 approach is not provided by ground-based precision or surveillance radar. Radar vectors to the final approach course may or may not be provided by ATC. Examples of nonradar approaches are VOR, NDB, TACAN, and ILS/MLS approaches. (See FINAL APPROACH COURSE.)(See FINAL APPROACH-IFR.)(See INSTRUMENT APPROACH PROCEDURE.)(See RADAR APPROACH.)b. Nonradar Approach Control. An ATC facility providing approach control service without the use of radar. (See APPROACH CONTROL FACILITY.)(See APPROACH CONTROL SERVICE.) c. Nonradar Arrival. An aircraft arriving at an airport without radar service or at an airport served by a radar facility and radar contact has not been established or has been terminated due to a lack of radar service to the airport. (See RADAR ARRIVAL.)(See RADAR SERVICE.)d. Nonradar Route. A flight path or route over which the pilot is performing his/her own navigation. The pilot may be receiving radar separation, radar monitoring, or other ATC services while on a nonradar route. (See RADAR ROUTE.)e. Nonradar Separation. The spacing of aircraft in accordance with established minima without the use of radar; e.g., vertical, lateral, or longitudinal separation. (See RADAR SEPARATION.)(See ICAO term NONRADAR SEPARATION.)NONRADAR SEPARATION [ICAO]. The separa-tion used when aircraft position information is derived from sources other than radar. NON.RESTRICTIVE ROUTING (NRR). Portions of a proposed route of flight where a user can flight plan the most advantageous flight path with no requirement to make reference to ground.based NAVAIDs. NOPAC. (See NORTH PACIFIC.)NORDO. (See LOST COMMUNICATIONS.)Pilot/Controller Glossary NORMAL OPERATING ZONE (NOZ). The NOZ is the operating zone within which aircraft flight remains during normal independent simultaneous parallel ILS approaches. NORTH AMERICAN ROUTE. A numerically coded route preplanned over existing airway and route systems to and from specific coastal fixes serving the North Atlantic. North American Routes consist of the following: a.Common Route/Portion. That segment of a North American Route between the inland navigation facility and the coastal fix. b.Noncommon Route/Portion. That segment of a North American Route between the inland navigation facility and a designated North American terminal. c.Inland Navigation Facility. A navigation aid on a North American Route at which the common route and/or the noncommon route begins or ends. d.Coastal Fix. A navigation aid or intersection where an aircraft transitions between the domestic route structure and the oceanic route structure. NORTH AMERICAN ROUTE PROGRAM (NRP). The NRP is a set of rules and procedures which are designed to increase the flexibility of user flight planning within published guidelines. NORTH MARK. A beacon data block sent by the host computer to be displayed by the ARTS on a 360 degree bearing at a locally selected radar azimuth and distance. The North Mark is used to ensure correct range/azimuth orientation during periods of CENRAP. NORTH PACIFIC. An organized route system between the Alaskan west coast and Japan. NOTAM. (See NOTICE TO AIRMEN.)NOTAM [ICAO]. A notice containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations. |
