Definition
The runway visual range measured by a transmissometer positioned near the rollout end of the runway — the section a landing aircraft uses to slow down and exit after touchdown. RVRR gives a horizontal visibility value (in feet or meters) representing how far a pilot can see down the runway from that point.
Plain English
It is a visibility reading taken near the far end of the runway, where an aircraft is rolling out after landing. It tells the pilot how far they will be able to see along the runway as they slow down.
Context Anchor
Seen in low-visibility airport weather information when visibility is reported for different parts of a runway.
Derivation
Runway visual range is the standard term for measured horizontal visibility along a runway. 'Rollout' refers to the landing rollout — the phase after touchdown when the aircraft decelerates on the runway. Together, RVRR specifies which segment of the runway the visibility reading applies to.
Why Pilots Care
Helps pilots decide if visibility is sufficient to complete a safe landing rollout or if a go-around is required.
Grounding Statement
Picture landing in fog: RVRR is the visibility report for the part of the runway you are rolling toward after touchdown.
Intuition Check
RVRR is not the length of the aircraft’s landing rollout. It is a visibility value for the rollout portion of the runway.
Example Sentence 1
The controller reported RVRR 2400, giving the crew confidence they would have enough visibility to slow and exit the runway after touchdown.
Example Sentence 2
With RVRR below 600 feet the approach was discontinued and a missed approach flown.
