RNAV APPROACH

−

 An instrument approach

procedure which relies on aircraft area navigation
equipment for navigational guidance.

(See AREA NAVIGATION (RNAV).)
(See INSTRUMENT APPROACH

PROCEDURE.)

ROAD RECONNAISSANCE (RC)

−

 Military activ-

ity requiring navigation along roads, railroads, and
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.)

ROTOR WASH

−

 A phenomenon resulting from the

vertical down wash of air generated by the main
rotor(s) of a helicopter.

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(See UNPUBLISHED ROUTE.)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
