2020-03-02 · RVR is only reported at airports that have RVR sensing equipment, when the visibility is 1 statue mile or less, or when RVR for an instrument runway is 6,000 feet or less. In a METAR, RVR starts with the runway, coded with the letter "R", followed by the runway number.

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. It is based on the measurement of a transmissometer made near the touchdown point of the instrument runway and is reported in hundreds of feet. Transmissometer technology provides today’s best visibility measurement accuracy for Runway Visual Range (RVR), and Vaisala’s LT31 is the most trusted and frequently used transmissometer the world over.

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.

Selected by German Weather Service DWD. It provides the optimal combination of the best accuracy, the highest reliability, broad measurement range, and low maintenance need. Low Visibility Operations Plan (LVOP): means a plan that calls for specific procedures established by the airport operator and/or ATC when aerodrome visibility is below RVR 1200 (¼ SM). Reduced Visibility Operations: means operations below RVR 2600 (½ SM) down to and including RVR 1200 (¼ SM). RVR is calculated from visibility, ambient light level, and runway light intensity.

Human Observer RVR as defined in RA 3275(2), Provision of Human Observed RVR. Where neither IRVR or Human Observed RVR are available controllers should derive RVR by converting the reported met visibility in accordance with the table at para 16. 9. RVR conversion should not be used for calculating take-off minima, Category II

How do you state the RVR values when the visibility condition is To the best of my knowledge there is no requirement for specific lighting to use converted meteorological visibility instead of RVR. And there is Visibility is ¾ statute miles, 3/4SM, and automated stations may put M in front of that. The runway visual range (RVR) for R17L is 2600 ft. Reportable values are ATC low visibility procedures at Schiphol are categorised in four phases: A, B, C, and D. These phases are based on Runway Visual Range values - RVR - and the published RVR.

"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).
