PCG R−4

RCAG−

(See REMOTE COMMUNICATIONS

AIR/GROUND FACILITY.)

RCC−

(See RESCUE COORDINATION CENTER.)

RCO−

(See REMOTE COMMUNICATIONS OUTLET.)

RCR−

(See RUNWAY CONDITION READING.)

READ BACK− Repeat my message back to me.

RECEIVER AUTONOMOUS INTEGRITY MON-

ITORING (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.

REDUCE SPEED TO (SPEED)−

(See SPEED ADJUSTMENT.)

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.)

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 emergen-

cy 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 special-

ists 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 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
