Visibility

Asked by: 6039 views FAA Regulations

What is the difference between Runway Visibility Value (RVV) and Runway Visual Range (RVR) ? Both use a  transmissometer so I do not understand why there is a difference.   Thanks for the feedback.

    In the simplest terms, the RVR value is the distance a pilot will see down the runway from the approach end. It is based on the sighting of either high intensity runway lights or on the visual contrast of other targets.

    RVV is the distance down the runway that a pilot can see unlighted objects.

    See Instrument Procedures Handbook, p. 2-8
