RANDOM ROUTE− Any route not established or

charted/published or not otherwise available to all

users.

RC−

(See ROAD RECONNAISSANCE.)

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 ADVISORY (RAA)−  A

remote service which may be provided by facilities,

which are not located on the landing airport, but have

a discrete ground−to−air communication frequency

or tower frequency when the tower is closed,

automated weather reporting with voice available to

the pilot at the landing airport, and a continuous

ASOS/AWSS/AWOS data display, other direct

reading instruments, or manual observation is

available to the FSS specialist.

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− An

unmanned communications facility remotely con-

trolled by air traffic personnel. RCOs serve FSSs.

RTRs 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.
