REMOTE COMMUNICATIONS OUTLET− An
unmanned communications facility remotely controlled
by air traffic personnel. RCOs serve FSSs.
RTRs serve terminal ATC facilities. An RCO or RTR
may be UHF or VHF and will extend the communication
range of the air traffic facility. There are several
classes of RCOs and RTRs. The class is determined
by the number of transmitters or receivers. Classes A
through G are used primarily for air/ground purposes.
RCO and RTR class O facilities are nonprotected

outlets subject to undetected and prolonged outages.
RCO (O’s) and RTR (O’s) were established for the
express purpose of providing ground-to-ground communications
between air traffic control specialists
and pilots located at a satellite airport for delivering
en route clearances, issuing departure authorizations,
and acknowledging instrument flight rules cancellations
or departure/landing times. As a secondary
function, they may be used for advisory purposes
whenever the aircraft is below the coverage of the
primary air/ground frequency.
REMOTE TRANSMITTER/RECEIVER−
(See REMOTE COMMUNICATIONS OUTLET.)
REPORT− Used to instruct pilots to advise ATC of
specified information; e.g., “Report passing Hamilton
VOR.”
REPORTING POINT− A geographical location in
relation to which the position of an aircraft is
reported.
(See COMPULSORY REPORTING POINTS.)
(See ICAO term REPORTING POINT.)
(Refer to AIM.)
REPORTING POINT [ICAO]− A specified geographical
location in relation to which the position of
an aircraft can be reported.
REQUEST FULL ROUTE CLEARANCE− Used
by pilots to request that the entire route of flight be
read verbatim in an ATC clearance. Such request
should be made to preclude receiving an ATC
clearance based on the original filed flight plan when
a filed IFR flight plan has been revised by the pilot,
company, or operations prior to departure.
REQUIRED NAVIGATION PERFORMANCE
(RNP)– A statement of the navigational performance
necessary for operation within a defined airspace.
The following terms are commonly associated with
RNP:
a. Required Navigation Performance Level or
Type (RNP-X). A value, in nautical miles (NM), from
the intended horizontal position within which an
aircraft would be at least 95-percent of the total flying
time.
b. Required Navigation Performance (RNP) Airspace.
A generic term designating airspace, route (s),
leg (s), operation (s), or procedure (s) where minimum
required navigational performance (RNP) have
been established.
c. Actual Navigation Performance (ANP). A measure
of the current estimated navigational performance.
Also referred to as Estimated Position Error
(EPE).
d. Estimated Position Error (EPE). A measure of
the current estimated navigational performance. Also
referred to as Actual Navigation Performance (ANP).
e. Lateral Navigation (LNAV). A function of area
navigation (RNAV) equipment which calculates,
displays, and provides lateral guidance to a profile or
path.
f. Vertical Navigation (VNAV). A function of area
navigation (RNAV) equipment which calculates,
displays, and provides vertical guidance to a profile
or path.
RESCUE COORDINATION CENTER− A search
and rescue (SAR) facility equipped and manned to
coordinate and control SAR operations in an area
designated by the SAR plan. The U.S. Coast Guard
and the U.S. Air Force have responsibility for the
operation of RCCs.
(See ICAO term RESCUE CO-ORDINATION
CENTRE.)
RESCUE CO-ORDINATION CENTRE [ICAO]− A
unit responsible for promoting efficient organization
of search and rescue service and for coordinating the
conduct of search and rescue operations within a
search and rescue region.
RESOLUTION ADVISORY−A display indication
given to the pilot by the traffic alert and collision
avoidance systems (TCAS II) recommending a
maneuver to increase vertical separation relative to an
intruding aircraft. Positive, negative, and vertical
speed limit (VSL) advisories constitute the resolution
advisories. A resolution advisory is also classified as
corrective or preventive
RESTRICTED AREA−
(See SPECIAL USE AIRSPACE.)
(See ICAO term RESTRICTED AREA.)
RESTRICTED AREA [ICAO]− An airspace of
defined dimensions, above the land areas or territorial
waters of a State, within which the flight of aircraft
