Overview

The Campbell Scientific Instrumented Runway Visual Range, or IRVR System provides an automated assessment of the distance an aircraft pilot can see the runway surface markings and lights.

The automated method of determining RVR, eliminates the error and inconsistencies associated with human observations and ensures reliable and efficient airport operations.

The system is scalable allowing for simple and economical solutions for smaller airfields but scaling up to a full three point sensor location system for CAT III runways at International Airports.

The system can operate as a stand-alone IRVR or provide IRVR data to a larger AWOS system.

Technical Description

The IRVR system utilises several optical sensors at between one and three locations. These locations equate to touch-down, mid-point and stop-end of the runway, depending on its current operating direction. Sensors operate on a network terminating at the IRVR Controller. The controller has the capability to output RVR, Aviation Visibility and if available Present Weather measurements to larger AWOS.
