What does RVR stand for in aviation weather reporting?

RVR stands for Runway Visual Range, which is a crucial measurement used in aviation to assess visibility conditions along a runway. It indicates the distance a pilot can see down the runway. This measurement is particularly important during low visibility situations, such as fog or heavy rain, as it helps determine whether it is safe for aircraft to take off or land.

Runway Visual Range is determined using a combination of sensors and visual observations, and it provides pilots with specific data about how far they can see before the runway becomes obscured. This information is essential for making informed decisions about flight safety during approach and landing phases.

Understanding RVR helps pilots adhere to visibility minimums set for different types of operations, which are critical in maintaining safe flight procedures, especially in adverse weather conditions.
