TERMINAL PUBLICATIONS. This metric is essential for safe In case of poor visibility, the direction can also be displayed per runway. ASOS station: COR: Correction to observation (CCA for Canada) Runway 4R RVR Runway visual range in meters (feet for the U. The wind is from direction 110° with a speed of 4 kt. ” The runway heading will follow the “R,” and in this example, “32L” represents runway 32-Left (C-Center, R-Right). “Runway Visual Range (RVR) is the range over which the pilot of an aircraft on the centre line of a runway can see the runway surface markings or the lights delineating the runway or identifying its centre line” (ICAO Annex 6: Operation of Aircraft). A METAR is a codified observation message indicating an airfield weather conditions observed at a given time. If the RVR during the 10 minutes before the observation time shows a distinct upward or downward tendency, U for The following is an example of a METAR, a surface observation, from O' Hare Airport. RVRs are communicated with the runway identifier followed by a slash and the visibility in feet followed by “FT” for feet. For example, if a storm rolls in or visibility suddenly drops, a SPECI will be issued to inform you about them. Runway Visual Range (RVR) plays a crucial role in aviation safety, and its reporting is essential for pilots and air traffic controllers alike. Some ASOS/AWOS sites are attended. R18R/1200U RVR for runway 18R is 1200 metres upward. It caused an METAR Examples. 9. In runways, an RVR VS is considered usable within an area defined by a circle centered at the RVR VS location, with a radius of 2,000 feet (4,000-foot diameter). 7SM – Airport visibility in statute miles or RVR Runway Visual Range (7 statute miles)-TSRA – Weather phenomenon reported (thunderstorms Special Reports (SPECI) are Aerodrome Weather Reports issued whenever weather conditions fluctuate about or are below specified criteria.

It further establishes Routine Weather Report (METAR) and/or an automated surface observing system (ASOS) transmission. 3. It will be in the format of the runway designator/meters, and can have a D, N or U to show its How Can You Read RVR In A METAR? Runway visual range is coded in the following format: the initial R is code for runway and is followed by a runway number. This will normally be the runway having the lowest instrument minima. (METAR) Example: METAR. 3 Straight-in approach minima are often expressed in terms of RVR. Let’s consider some real-world examples of RVR readings in action: If an airport reports an RVR of 600 feet due to heavy Runway Visual Range (RVR) RVR will be reported from aerodromes with RVR instrumentation whenever the RVR or the visibility are less than 1,500 m. Administration Advancement Example: An RVR of 4000 is equal to 3/4 statute mile visibility (Figure 7-15). The METAR is a specialized format that contains everything the observer needs to record. Note the bold runway visual range (RVR) indications. RVR Visibility Sensor Requirements. Surface wind: mean 300 deg true, 25 KT; maximum 37 KT, varying Runway Visual Range (RVR) may also be reported, indicating visibility down the runway.
