Summary
This white paper discusses the LiDAR Windshear Alerting System (LiWAS), which enhances windshear alerting systems in airports. It outlines the system's ability to track headwind and tailwind changes, integrating with existing Low-Level Windshear Alerting Systems (LLWAS) or functioning independently. The paper details the components and methodologies of LiWAS, emphasizing the detection algorithm and configuration tool. It explains the significance of windshear in aviation safety, particularly during takeoff and landing phases, and categorizes windshear events. The document describes how LiWAS utilizes a Glide-Path Optimal Scanning Strategy Generator (GPOSS) for real-time wind data collection and analysis. It also highlights the system's testing at Bilbao Airport, showcasing its performance in adverse conditions. The paper concludes with the benefits of LiWAS, including improved detection range and integration with DTN Weather Systems, which enhances operational safety for air traffic controllers.
