What does RVR indicate?

• A. The horizontal visibility distance along the runway
• B. The vertical visibility above the runway
• C. The total runway length
• D. The maximum instrument visibility range

Answer: (A)

RVR, or Runway Visual Range, indicates the horizontal visibility along the runway. It measures how far down the runway a pilot can see the runway surface, lights, and markings from a given point on the runway, along the runway axis in the direction of travel. This is different from vertical visibility, the total length of the runway, or a general instrument visibility range. RVR values are reported for each runway end (and sometimes for different parts of the runway) and are used to determine whether takeoff or landing minima are met under current conditions.
