RVR (Runway Visual Range) is considered to be better representation of expected distance that the pilot may acquire visual cues on approach than meteorological office reported horizontal visibility. Effect of lighting intensities and background luminescence play a role when establishing an RVR. RVR is horizontal visual range, not slant visual range. b. Touchdown RVR Visibility Sensor (VS). The touchdown RVR VS is located near the touchdown end of the runway and is installed in accordance with the criteria stated in this order and the applicable standard installation drawings. c. Mid-Point RVR VS. specification (FAA, 2003) for RVR systems that details specific visibility sensor (VS) and ambient light sensor (ALS) performance requirements for use in procuring a new PC-Based RVR system.

When RVR indicates a reportable value regardless of the prevailing visibility. 2.6.2 If the aerodrome system is not designed to calculate the RVR and the reported visibility takes into account 1000 cd lights, the higher valid conversion factor between this visibility and an equivalent RVR, for night condition and HI lighting, would be 1.3. The direct use of the reported visibility would be much easier than a CMV. 1. Horizontal visibility aspects 2. Visual range 3. Observing techniques of RVR 4. Observing of RVR 5.

From Wikipedia, the free encyclopedia. Jump to navigation Jump to search. A pilot's view of Lisbon Airport 's runway 21 in fog; runway visual range is about 200 m (660 ft) In aviation, the runway visual range ( RVR) is the distance over which a pilot of an aircraft on the centreline of the runway can see the runway surface markings delineating the runway or identifying its centre line.

MOR ranges from 10 to 10,000 meters. The Transmissometer is known as transmittance meter as it is an instrument which is used to measure transmission coefficient of light passing through atmosphere and hence determine RVR and/or MOR.
RVR - Runway Visual Range - the maximum distance at which the runway, or the specified lights or markers delineating it, can be seen from a position above a specified point on its center line. This value is normally determined by visibility sensors located alongside and higher than the center line of the runway. Reportable values are RVR 6,000 feet or less. When it is determined from a reliable source that the indicated RVR value differs by more than 400 feet from the actual conditions within the area of the transmissometer, the RVR data is not acceptable and must not be reported.
RVR is reported in either feet or meters. In the United States, you can assume it is in feet. This may seem like a no brainer, but RVR is only reported at airports with an RVR system installed. If you only see visibility reported in statute miles on the METAR, the airport probably doesn’t have RVR. The lower the visibility, the smaller the increments that RVR is reported: Every 100 feet, up to 1,000 feet Every 200 feet from 1,000 feet to 3,000 feet Every 500 feet from 3,000 feet to 6,000 feet It is based on the sighting of either high intensity runway lights or on the visual contrast of other targets whichever yields the greater visual range.

It's based on eye performance and available distinctive features of the surrounding environment. Moreover, visibility isn't generally evaluated for the same volume of atmosphere than RVR. Runway Visual Range (RVR) and Runway Visibility are two terms which have similar meanings.

Visibility, contrary to RVR, is not an exact measure. It's based on eye performance and available distinctive features of the surrounding environment. Moreover, visibility isn't generally evaluated for the same volume of atmosphere than RVR. Runway Visual Range (RVR) and Runway Visibility are two terms which have similar meanings. Both are used to indicate the visibility along the intended take off or landing path. The difference between the two is about how the visibility is determined. RVR is determined by electronic sensing equipment and is associated with Category 1 ILS approaches Landing minima consist of both visibility and/or RVR, and cloud base elements. An instrument approach may not be continued beyond the outer marker fix in the case of a precision approach or below 1,000 ft aal in the case of a non-precision approach, unless the reported visibility or RVR is above the specified minimum.

The advantage of the RVR system is it gives you an excellent idea of what’s happening on the runway. Visibility, contrary to RVR, is not an exact measure.
