Pilot/Controller Glossary
secondary function, they may be used for advisory
purposes whenever the aircraft is below the coverage
of the primary air/ground frequency.
REMOTE PILOT IN COMMAND (RPIC)
−
The
RPIC is directly responsible for and is the final
authority as to the operation of the unmanned aircraft
system.
REMOTE TRANSMITTER/RECEIVER (RTR)
−
(See REMOTE COMMUNICATIONS OUTLET.)
REPORT
−
Used to instruct pilots to advise ATC of
specified information; e.g., “Report passing Hamil-
ton 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 geo-
graphical 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.
Advanced
−
Required Navigation Performance
(A
−
RNP). A navigation specification based on RNP
that requires advanced functions such as scalable
RNP, radius
−
to
−
fix (RF) legs, and tactical parallel
offsets. This sophisticated Navigation Specification
(NavSpec) is designated by the abbreviation
“A
−
RNP”.
c.
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.
d.
Actual Navigation Performance (ANP). A
measure of the current estimated navigational
performance. Also referred to as Estimated Position
Error (EPE).
e.
Estimated Position Error (EPE). A measure of
the current estimated navigational performance. Also
referred to as Actual Navigation Performance (ANP).
f.
Lateral Navigation (LNAV). A function of area
navigation (RNAV) equipment which calculates,
displays, and provides lateral guidance to a profile or
path.
g.
Vertical Navigation (VNAV). A function of area
navigation (RNAV) equipment which calculates,
displays, and provides vertical guidance to a profile
or path.
REROUTE IMPACT ASSESSMENT (RRIA)
−
A
capability within the Traffic Flow Management
System that is used to define and evaluate a potential
reroute prior to implementation, with or without
miles
−
in
−
trail (MIT) restrictions. RRIA functions
estimate the impact on demand (e.g., sector loads)
and performance (e.g., flight delay). Using RRIA,
traffic management personnel can determine whether
the reroute will sufficiently reduce demand in the
Flow Constraint Area and not create excessive “spill
over” demand in the adjacent airspace on a specific
route segment or point of interest (POI).
RESCUE COORDINATION CENTER (RCC)
−
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 System (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
