PCG N−3

a. Nonradar Approach. Used to describe

instrument approaches for which course guidance on

final 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, ILS, RNAV, and GLS 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.)

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 (No Radio)− Aircraft that cannot or do not

communicate by radio when radio communication is

required are referred to as “NORDO.”

(See LOST COMMUNICATIONS.)

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 ATLANTIC HIGH LEVEL AIRSPACE

(NAT HLA)− That volume of airspace (as defined in

ICAO Document 7030) between FL 285 and FL 420

within the Oceanic Control Areas of Bodo Oceanic,

Gander Oceanic, New York Oceanic East, Reykjavik,

Santa Maria, and Shanwick, excluding the Shannon

and Brest Ocean Transition Areas. ICAO Doc 007

North Atlantic Operations and Airspace Manual

provides detailed information on related aircraft and

operational requirements.
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.
NOT STANDARD− Varying from what is expected

or published. For use in NOTAMs only.
NOT STD

-

(See NOT STANDARD.)
