(See ICAO term RESTRICTED AREA.)RESTRICTED AREA [ICAO]. An airspace of defined dimensions, above the land areas or territorial waters of a State, within which the flight of aircraft is restricted in accordance with certain specified conditions. RESUME NORMAL SPEED. Used by ATC to advise a pilot that previously issued speed control restrictions are deleted. An instruction to “resume normal speed” does not delete speed restrictions that are applicable to published procedures of upcoming segments of flight, unless specifically stated by ATC. This does not relieve the pilot of those speed restrictions which are applicable to 14 CFR Section 91.117. RESUME OWN NAVIGATION. Used by ATC to advise a pilot to resume his/her own navigational responsibility. It is issued after completion of a radar PCG R.5 vector or when radar contact is lost while the aircraft is being radar vectored. (See RADAR CONTACT LOST.)(See RADAR SERVICE TERMINATED.)RMI. (See RADIO MAGNETIC INDICATOR.)RNAV. (See AREA NAVIGATION (RNAV).)(See ICAO Term 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.)ROAD RECONNAISSANCE. 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.)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 (See AIRWAY.)(See JET ROUTE.)(See PUBLISHED ROUTE.)(See UNPUBLISHED ROUTE.)ROUTE ACTION NOTIFICATION. URET notifi-cation that a PAR/PDR/PDAR has been applied to the flight plan. (See ATC PREFERRED ROUTE NOTIFICATION.)(See USER REQUEST EVALUATION 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 take-off of aircraft. RUNWAY CENTERLINE LIGHTING. (See AIRPORT LIGHTING.)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 END IDENTIFIER LIGHTS. (See AIRPORT LIGHTING.)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 PCG R.6 magnetic heading of the runway centerline 044, fly 044. RUNWAY IN USE/ACTIVE RUNWAY/DUTY RUNWAY. Any runway or runways currently being used for takeoff or landing. When multiple runways are used, they are all considered active runways. In the metering sense, a selectable adapted item which specifies the landing runway configuration or direction of traffic flow. The adapted optimum flight plan from each transition fix to the vertex is determined by the runway configuration for arrival metering processing purposes. RUNWAY LIGHTS. (See AIRPORT LIGHTING.)RUNWAY MARKINGS. (See AIRPORT MARKING AIDS.)RUNWAY OVERRUN. In military aviation exclu-sively, a stabilized or paved area beyond the end of a runway, of the same width as the runway plus shoulders, centered on the extended runway centerline. RUNWAY PROFILE DESCENT. An instrument flight rules (IFR) air traffic control arrival procedure to a runway published for pilot use in graphic and/or textual form and may be associated with a STAR. Runway Profile Descents provide routing and may depict crossing altitudes, speed restrictions, and headings to be flown from the en route structure to the point where the pilot will receive clearance for and execute an instrument approach procedure. A Runway Profile Descent may apply to more than one runway if so stated on the chart. (Refer to AIM.)RUNWAY SAFETY AREA. A defined surface surrounding the runway prepared, or suitable, for reducing the risk of damage to airplanes in the event of an undershoot, overshoot, or excursion from the runway. The dimensions of the RSA vary and can be determined by using the criteria contained within AC 150/5300-13, Airport Design, Chapter 3. Figure 3.1 in AC 150/5300-13 depicts the RSA. The design standards dictate that the RSA shall be: |
