Pilot/Controller Glossary

RELEASE TIME [ICAO]- Time prior to which an aircraft should be given further clearance or prior to which
it should not proceed in case of radio failure.
REMOTE AIRPORT INFORMATION SERVICE (RAIS)- A temporary service provided by facilities, which
are not located on the landing airport, but have communication capability and automated weather reporting
available to the pilot at the landing airport.
REMOTE COMMUNICATIONS AIR/GROUND FACILITY- An unmanned VHF/UHF transmitter/receiver
facility which is used to expand ARTCC air/ground communications coverage and to facilitate direct contact
between pilots and controllers. RCAG facilities are sometimes not equipped with emergency frequencies
121.5 MHz and 243.0 MHz.
(Refer to AIM.)

REMOTE COMMUNICATIONS OUTLET (RCO)- An unmanned communications facility remotely
controlled by air traffic personnel. RCOs serve FSSs. Remote Transmitter/Receivers (RTR) 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 IDENTIFICATION (RID)- A system for electronic identification and secure oversight of UAS.
(See 4 CFR Part 89)
(See AIM)

REMOTE PILOT- Pilot of a UAS who is not operating as a recreational flyer under 49 USC 44809, the
Exception for Limited Recreational Operations of Unmanned Aircraft.
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 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.
