No. RVR-6000 - Runway Visual Range
- meets or exceeds ICAO recommendations, WMO requirements - continues Belfort’s reputatation for supierior visibility sensors - specifically manufactured for RVR applications - latest forward scatter sensor technology - compatable with CAT I, II, or IIIB airports
The Belfort RVR system consists of: the model 6000 visibility sensor known worldwide as a standard in visibility measurement the ambient light sensor (ALS) the runway light interface (RWIS) the proprietary RVR software program
The RVR system measures the transparency of the atmosphere and calculates an extension coefficient taking in to affect the ambient light conditions. When the runway light intensity is integrated into the RVR algorithm, runway visual range values are determined. The Belfort forward scatter visibility sensor provides accurate measurements in all weather conditions, including fog, smoke, heavy precipitation and snow. Adding the high performance of the Model 6000 visibility sensor with the proven RVR algorithms insure the most accurate runway visual range values are reported to the users. The Model 6000 visibility sensors, used in the RVR system, have been calibrated through a specific chain of standards traceable to a reference “transmissometer”. Using this calibration standard ensures that the runway visual range measurements and calculations meet aviation quality standards
