The FAA is now providing real-time Runway Visual Range (RVR) data to FAA facilities and air carriers. The RVR system at an airport reports RVR values from 0 to 6500 feet that, roughly speaking, represent the distance that a pilot is able to see down the runway. For a fully instrumented runway, RVR values are given for the touchdown, midpoint, and rollout portions of the runway, along with an indication of whether the values are increasing, decreasing, or stationary; in addition, the status of edge and centerline lights is given. Every two seconds, an RVR value is reported that is an average of the values over the last minute.

The Enhanced Traffic Management System (ETMS) acquires RVR data from the airports that have the New Generation RVR system. These airports feed the RVR data to one of the thirty-one TRACONs that are ETMS remote sites; these TRACONs are chosen because communications lines already exist between these TRACONs and the ETMS hub site, which is at the Volpe Center. From the ETMS hub site, the data is distributed to the end users at FAA facilities and at air carriers both in a digital feed of data and also through a web page located at the Air Traffic Control System Command Center.
