What is the RCR value for a wet runway?

The RCR, or Runway Condition Reading, is a value that indicates the level of braking effectiveness on a runway surface. For a wet runway, the commonly accepted RCR value is typically around 12. This value reflects the reduction in braking capability due to the presence of water on the runway, which can significantly affect aircraft performance during takeoff and landing.

When evaluating runway conditions, pilots and flight crews utilize RCR values to make informed decisions regarding landing distances, speed profiles, and overall safety. A wet runway has a higher RCR than one that is icy or covered in snow, but it still presents challenges compared to a dry runway. The RCR of 12 signifies that while there is some braking ability available, pilots must be cautious and adjust their approach accordingly.

This understanding helps pilots in planning safe operations in varying weather conditions and enhances situational awareness regarding the runway's capacity to support safe landings.
