Pilot/Controller Glossary

RESUME PUBLISHED SPEED- Used by ATC to advise a pilot to resume published speed restrictions that
are applicable to a SID, STAR, or other instrument procedure. It is issued to terminate a speed adjustment where
speed restrictions are published on a charted procedure.
RHA-
(See REFINED HAZARD AREA.)

RID-
(See REMOTE IDENTIFICATION.)

RMI-
(See RADIO MAGNETIC INDICATOR.)

RNAV-
(See AREA NAVIGATION (RNAV).)

RNAV APPROACH- An instrument approach procedure which relies on aircraft area navigation equipment for
navigational guidance.
(See AREA NAVIGATION (RNAV).)
(See INSTRUMENT APPROACH PROCEDURE.)

RNAV VISUAL FLIGHT PROCEDURE (RVFP)- An RVFP is a special visual flight procedure flown on an
IFR flight plan. It is flown in visual conditions and clear of clouds must be maintained. An RVFP is flown using
an approved RNAV system to maintain published lateral and vertical paths to runways without an instrument
approach procedure. It requires an ATC clearance and may begin at other points along the path of the charted
procedure when approved by ATC. An RVFP is not published in the Federal Register for public use and the
operator is required to have a specific Operations Specification approval. Required ceiling and visibility minima
are published on the procedure chart. An RVFP does not have a missed approach procedure and is not evaluated
for obstacle protection.
ROAD RECONNAISSANCE (RC)- Military activity 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.
ROUND-ROBIN FLIGHT PLAN- A single flight plan filed from the departure airport to an intermediary
destination(s) and then returning to the original departure airport.
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(See UNPUBLISHED ROUTE.)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 notification that a PAR/PDR/PDAR has been applied to the flight
plan.
(See ATC PREFERRED ROUTE NOTIFICATION.)
(See EN ROUTE DECISION SUPPORT TOOL.)
