Runway Visual Range
|Term||Runway Visual Range|
An instrumentally derived value, based on standard calibrations, that represents 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.

The runway visual range is based on the sighting of either high intensity runway lights or on the visual contrast of other targets, whichever yields the greater visual range.
