Smaller airports will typically not be set up to provide RVR readings. 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 FAA - American RVR Monitors Flight Crew Guide - Conversion of reported meteorological visibility to RVR Patrick Veillette, Ph.D. (Jun 25, 2019). "When Visibility And Ceiling Reports Differ From A Pilot's Perception" . $\begingroup$ RVR has more precision (increments of 100 feet vs 1/8 mile), which in & of itself isn't the same as greater accuracy, but when the visibility varies between one runway and another (and the point where prevailing visibility is measured), RVR is the more precise AND more accurate indication of your runway's current conditions. meaningful predictions of RVR from prevailing visibility reports can only be accomplished if the assessment of both RVR and visibility is by reference to common sensor(s). The need to retain flexibility in the application of recommendation 4.3.1.1 of Appendix 3 to the Annex that calls for RVR to be assessed at a height of approximately 2.5 m should be noted.

Visibility is measured by either electronic May 3, 2017 A typical RVR system is created around a visibility sensor, an ambient light sensor, a runway light intensity monitor, a data processing unit and a 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 Prevailing visibility should be reported in METAR and SPECI code forms.

A blank value for RVR on the display indicates that no RVR system visibility sensor is needed for that precision point on the runway based on the instrumentation and landing category of that runway. Each RVR value for TD, MP, or RO is displayed in feet, ranging from 0000 to 6000.

b) Lowest standard visibility or RVR without approach lights is: To calculate RVR an automated system must measure the local visibility, the ambient or background brightness and the intensity of the runway lights. The calculation of RVR is described by ICAO publication 9328, Manual of Runway Visual Range Observing and Reporting Practices.

RVR conversion should not be used for calculating take-off minima, Category II or III minima or when RVR or IRVR is available. Guidance Material 3275(1) Provision of Runway Visual Range/Instrumented Runway Visual This time an actual CAT III approach is shown with RVR (runway visual range) of 300 metres in the touch down zone.
(Refer to 14 CFR Part 91.) (Refer to AIM.) Flight Visibility- The average forward horizontal distance, It is reported whenever the RVR or the prevailing visibility is less than 1500 metres. RVR is only approved for use during low visibility conditions characterised by Various types of RVR are: (1) Touchdown RVR. The RVR visibility readout values obtained from RVR equipment serving the runway touchdown zone.
