AviMet? FAA Certified Runway Visual Range System (RVR)

provides accurate and reliable measurements in all weather conditions, using forward scatter measurements made with a near infrared LED light source. As a result of cooperation between the FAA and Vaisala, the FS11’s performance has been optimized for RVR applications. The FS11 incorporates extensive internal diagnostics and comes equipped with high-power heaters to prevent snow accumulation and dew formation, and also includes a proven window contamination compensation algorithm.

accurately measures total ambient light and raises background luminance measurement to a new level of reliability. It comes equipped with intelligent monitoring and contamination compensation features. Window, hood and electronic heaters ensure reliable measurements in all weather conditions.

is an essential part of the RVR system. It accurately measures and determines the current flowing through the runway edge and centerline light circuits. This information is used to determine the intensity settings of the runway lights. Each Vaisala RLIM unit can accept input from up to eight current sensors.

is designed to exceed FAA’s extensive human engineering requirements in a busy ATCT environment. The display is a touch screen design with easy user configuration and diagnostics tools. The displays report touchdown, midpoint and rollout zone RVR, and edge and centerline runway light step settings for up to three user-selected runways. LVAT limits for each zone can be selected from a touch screen menu.

accepts and integrates data from up to 30 Visibility Sensors, two Ambient Light Sensors, 10 Runway Light Intensity Monitors and supports hundreds of Controller Displays. The high reliability of the DPU is achieved by using redundant server-grade computers and mirrored data storage.
