NONRADAR

−

 Precedes other terms and generally

means without the use of radar, such as:

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.
