PCG R−6

rivers. Reconnaissance route/route segments are

seldom along a straight line and normally require a

lateral route width of 10 NM to 30 NM and an altitude

range of 500 feet to 10,000 feet AGL.
ROGER−  I have received all of your last

transmission. It should not be used to answer a

question requiring a yes or a no answer.

(See AFFIRMATIVE.)
(See NEGATIVE.)

ROLLOUT RVR−

(See VISIBILITY.)

ROUTE− A defined path, consisting of one or more

courses in a horizontal plane, which aircraft traverse

over the surface of the earth.

(See AIRWAY.)
(See JET ROUTE.)
(See PUBLISHED ROUTE.)
(See UNPUBLISHED ROUTE.)

ROUTE ACTION NOTIFICATION− EDST notifi-

cation that a PAR/PDR/PDAR has been applied to the

flight plan.

(See ATC PREFERRED ROUTE

NOTIFICATION.)

(See EN ROUTE DECISION SUPPORT TOOL.)

ROUTE SEGMENT− As used in Air Traffic Control,

a part of a route that can be defined by two

navigational fixes, two NAVAIDs, or a fix and a

NAVAID.

(See FIX.)
(See ROUTE.)
(See ICAO term ROUTE SEGMENT.)

ROUTE SEGMENT [ICAO]− A portion of a route to

be flown, as defined by two consecutive significant

points specified in a flight plan.
RSA−

(See RUNWAY SAFETY AREA.)

RTR−

(See REMOTE TRANSMITTER/RECEIVER.)

RUNWAY− A defined rectangular area on a land

airport prepared for the landing and takeoff run of

aircraft along its length. Runways are normally

numbered in relation to their magnetic direction

rounded off to the nearest 10 degrees; e.g., Runway

1, Runway 25.

(See PARALLEL RUNWAYS.)
(See ICAO term RUNWAY.)

RUNWAY [ICAO]− A defined rectangular area on a

land aerodrome prepared for the landing and takeoff

of aircraft.
RUNWAY CENTERLINE LIGHTING−

(See AIRPORT LIGHTING.)

RUNWAY CONDITION CODES (RwyCC)− Nu-

merical readings, provided by airport operators, that

indicate runway surface contamination (for example,

slush, ice, rain, etc.). These values range from “1”

(poor) to “6” (dry) and must be included on the ATIS

when the reportable condition is less than 6 in any one

or more of the three runway zones (touchdown,

midpoint, rollout).
RUNWAY CONDITION READING− Numerical

decelerometer readings relayed by air traffic

controllers at USAF and certain civil bases for use by

the pilot in determining runway braking action.

These readings are routinely relayed only to USAF

and Air National Guard Aircraft.

(See BRAKING ACTION.)

RUNWAY CONDITION REPORT (RwyCR)−  A

data collection worksheet used by airport operators

that correlates the runway percentage of coverage

along with the depth and type of contaminant for the

purpose of creating a FICON NOTAM.

(See RUNWAY CONDITION CODES.)

RUNWAY END IDENTIFIER LIGHTS (REIL)−

(See AIRPORT LIGHTING.)

RUNWAY ENTRANCE LIGHTS (REL)−An array

of red lights which include the first light at the hold

line followed by a series of evenly spaced lights to the

runway edge aligned with the taxiway centerline, and

one additional light at the runway centerline in line

with the last two lights before the runway edge.
RUNWAY GRADIENT− The average slope, mea-

sured in percent, between two ends or points on a

runway. Runway gradient is depicted on Government

aerodrome sketches when total runway gradient

exceeds 0.3%.
RUNWAY HEADING− The magnetic direction that

corresponds with the runway centerline extended, not

the painted runway number. When cleared to “fly or

maintain runway heading,” pilots are expected to fly

or maintain the heading that corresponds with the

extended centerline of the departure runway. Drift

correction shall not be applied; e.g., Runway 4, actual

magnetic heading of the runway centerline 044, fly

044.
