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 visibility difference

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.

Again rough equivalences are in place: 1/4 SM = 400 m; 1 SM = 1,600 m. 1 NM = 1 1/4 SM. Unlike flight visibility, ground visibility refers to how far you can see near the Earth's surface - a determination that is made and reported by the National Weather Service or by an accredited observer.

Until such time that slant visual range observations are available 'runway visual range' (RVR) observations are made in conditions of restricted visibility.

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 extended to a higher limit (why not 10 km), a conversion of the reported visibility to CMV would not be necessary. 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 RVR unit conversion.

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. RVR, in contrast to prevailing or runway visibility, is based on what a pilot in a moving aircraft should see looking down the runway. RVR is horizontal visual range, not slant visual range.

This may seem like a no brainer, but RVR is only reported at airports with an RVR system installed.

Each RVR value for TD, MP, or RO is displayed in feet, ranging from 0000 to 6000. A display of >6000 indicates that the RVR is greater than 6000 feet.
