Pilot/Controller Glossary 

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 (RNP­X). A value, in nautical miles (NM), from 
the intended horizontal position within which an 
aircraft would be at least 95­percent 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 CO­ORDINATION 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 
advisories. A resolution advisory is also classified as 
corrective or preventive.
