RCAG-

RCO-
(See REMOTE COMMUNICATIONS OUTLET.)

RCR-
(See RUNWAY CONDITION READING.)

READ BACK- Repeat my message back to me.
RECEIVER AUTONOMOUS INTEGRITY MONITORING (RAIM)- A technique whereby a civil
GNSS receiver/processor determines the integrity of
the GNSS navigation signals without reference to
sensors or non-DoD integrity systems other than the
receiver itself. This determination is achieved by a
consistency check among redundant pseudorange
measurements.
RECEIVING CONTROLLER- A controller/facility
receiving control of an aircraft from another
controller/facility.
RECEIVING FACILITY-
(See RECEIVING CONTROLLER.)

RECONFORMANCE- The automated process of
bringing an aircraft"s Current Plan Trajectory into
conformance with its track.

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 TRANSMITTER/RECEIVER (RTR)-

(See SPEED ADJUSTMENT.)

REPORT- Used to instruct pilots to advise ATC of
specified information; e.g., "Report passing Hamilton VOR."

REIL-
(See RUNWAY END IDENTIFIER LIGHTS.)

RELEASE TIME- A departure time restriction
issued to a pilot by ATC (either directly or through an
authorized relay) when necessary to separate a
departing aircraft from other traffic.
(See ICAO term RELEASE TIME.)

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.)

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.

REPORTING POINT [ICAO]- A specified geographical location in relation to which the position of
an aircraft can be reported.

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.

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
