Vaisala AviMet® Runway Visual Range System comprises a visibility sensor, a background luminance meter and a computer that calculates the RVR values. The visibility sensor is offered in two forms: transmissometer or forward scatter meter. The RVR computer collects the visibility data the background luminance data and runway light setting data. Based on this data, it calculates the RVR values. RVR messages and alarms are distributed to output devices.
Vaisala AviMet® RVR is designed to interface with various output communication formats and to meet various communication standards and conventions. Furthermore, the data outputs are transmitted accurately via various communication media.
AviMet® RVR is part of the AviMet® technology platform. Other major systems based on the platform are: Vaisala AviMet® Low-Level Windshear Alert System (LLWAS) and Vaisala AviMet® Automated Weather Observing System (AWOS). Each of these can be easily and fully integrated together.
