published RNAV routes used by the United States.
QNE- The barometric pressure used for the standard
altimeter setting (29.92 inches Hg.).
QNH- The barometric pressure as reported by a
particular station.
QUADRANT- A quarter part of a circle, centered on
a NAVAID, oriented clockwise from magnetic north
as follows: NE quadrant 000‐089, SE quadrant
090‐179, SW quadrant 180‐269, NW quadrant
270‐359.
QUEUING-
(See STAGING/QUEUING.)
QUICK LOOK- A feature of the EAS and ARTS
which provides the controller the capability to
display full data blocks of tracked aircraft from other
control positions.

RADAR- A device which, by measuring the time
interval between transmission and reception of radio
pulses and correlating the angular orientation of the
radiated antenna beam or beams in azimuth and/or
elevation, provides information on range, azimuth,
and/or elevation of objects in the path of the
transmitted pulses.
a. Primary Radar- A radar system in which a
minute portion of a radio pulse transmitted from a site
is reflected by an object and then received back at that
site for processing and display at an air traffic control
facility.
b. Secondary Radar/Radar Beacon (ATCRBS)- A
radar system in which the object to be detected is
fitted with cooperative equipment in the form of a
radio receiver/transmitter (transponder). Radar
pulses transmitted from the searching transmitter/receiver
(interrogator) site are received in the
cooperative equipment and used to trigger a
distinctive transmission from the transponder. This
reply transmission, rather than a reflected signal, is
then received back at the transmitter/receiver site for
processing and display at an air traffic control facility.
(See INTERROGATOR.)
(See TRANSPONDER.)
(See ICAO term RADAR.)
(Refer to AIM.)
RADAR [ICAO]- A radio detection device which
provides information on range, azimuth and/or
elevation of objects.
a. Primary Radar- Radar system which uses
reflected radio signals.
b. Secondary Radar- Radar system wherein a
radio signal transmitted from a radar station initiates
the transmission of a radio signal from another
station.
RADAR ADVISORY- The provision of advice and
information based on radar observations.
(See ADVISORY SERVICE.)
RADAR ALTIMETER-
(See RADIO ALTIMETER.)
RADAR APPROACH- An instrument approach
procedure which utilizes Precision Approach Radar
(PAR) or Airport Surveillance Radar (ASR).
(See AIRPORT SURVEILLANCE RADAR.)
(See INSTRUMENT APPROACH
PROCEDURE.)
(See PRECISION APPROACH RADAR.)
(See SURVEILLANCE APPROACH.)
(See ICAO term RADAR APPROACH.)
(Refer to AIM.)
RADAR APPROACH [ICAO]- An approach,
executed by an aircraft, under the direction of a radar
controller.
RADAR APPROACH CONTROL FACILITY- A
terminal ATC facility that uses radar and nonradar
capabilities to provide approach control services to
aircraft arriving, departing, or transiting airspace
controlled by the facility.
(See APPROACH CONTROL SERVICE.)
a. Provides radar ATC services to aircraft
operating in the vicinity of one or more civil and/or
military airports in a terminal area. The facility may
provide services of a ground controlled approach
(GCA); i.e., ASR and PAR approaches. A radar
approach control facility may be operated by FAA,
USAF, US Army, USN, USMC, or jointly by FAA
and a military service. Specific facility nomenclatures
are used for administrative purposes only and
are related to the physical location of the facility and
the operating service generally as follows:
1. Army Radar Approach Control (ARAC)
(Army).
2. Radar Air Traffic Control Facility (RATCF)
(Navy/FAA).
3. Radar Approach Control (RAPCON) (Air
Force/FAA).
4. Terminal Radar Approach Control
(TRACON) (FAA).
5. Air Traffic Control Tower (ATCT) (FAA).
(Only those towers delegated approach control
authority.)
RADAR ARRIVAL- An aircraft arriving at an
airport served by a radar facility and in radar contact
with the facility.
(See NONRADAR.)

RADAR BEACON-
(See RADAR.)
RADAR CLUTTER [ICAO]- The visual indication
on a radar display of unwanted signals.
RADAR CONTACTa.
Used by ATC to inform an aircraft that it is
identified on the radar display and radar flight
following will be provided until radar identification
