Belfort Instrument Company presents its Runway Visual Range (RVR) system as a part of the company’s commitment to flight information and safety.
- Meets or exceeds ICAO recommendations, WMO requirements
- Continues Belfort’s reputation for superior visibility sensors
- Specifically manufactured for Runway Visual Range (RVR) applications
- Latest forward scatter sensor technology
- Compatible with CAT I, II, or IIIB Airports
- Can be used as a stand-alone RVR or integrated with our AWOS unit
The RVR system consists of our Model 6000 visibility sensor known worldwide as a standard in visibility measurement, the Belfort ambient light sensor (ALS), the Belfort runway light interface (RWIS), and the proprietary RVR software program. Belfort’s 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 our 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.
