The Teledyne Runway Visual Range (RVR) system is an automated computer-controlled visibility measurement and monitoring system for use in US airports. This state-of-the-art solution is designed to report to the air traffic controller the minimum visibility limits existing on airport runways, and therefore assists in navigation and landings under extreme weather conditions.
Teledyne's RVR solution is the only forward scatter RVR system in the world certified by the FAA for CAT IIIb operations (down to 150 ft or 50 m RVR). This certification was achieved after extensive testing under some of the worst operating situations. Unlike other transmissometer systems that often shut down under extreme weather conditions, Teledyne's RVR system offers a high level of reliability, ensuring accurate information in any situation. Each of the RVR sensors is thoroughly tested to assure calibration consistency; and a laser based Coordinate Measuring Machine (CMM) checks the tight tolerances on the various critical dimensions of the sensor fork.
The RVR system has extensive built-in Remote Maintenance Monitoring (RMM) features, allowing technicians from a local or remote location to monitor the health of the system, run diagnostics, and isolate potential faults on a removable module. These RMM features, coupled with the modular nature of the system and the easy accessibility to all sub-assemblies assure a very low Mean-Time-to-Repair (less than 30 minutes).
The average periodic RVR system maintenance time is over 90 days. This extremely low maintenance is made possible by continuously monitoring sensor optics contamination, and correcting it with sophisticated algorithms that were developed after many months of field and laboratory testing.
The RVR system is also designed to assure that the system is fail-safe and does not output erroneous data.
A Teledyne Controls RVR System is now installed in about 200 major airports throughout the United States, and it is projected that additional 120 airports will be equipped with this system in the near future.
