Our Wind Shear Detection solutions are an integral part of our Aviation Weather Systems, designed to enhance flight safety by providing accurate and timely detection of hazardous wind variations in the vicinity of airports. Wind shear—sudden changes in wind speed and direction—poses a significant risk during critical flight phases such as takeoff and landing. Our advanced systems enable early detection, real-time monitoring, and reliable alerting to support proactive decision-making by pilots and air traffic controllers.
Engineered in compliance with international aviation standards, our wind shear solutions ensure high reliability, rapid response, and seamless integration with existing airport and air traffic management infrastructure. By delivering precise and actionable information, these systems help minimize operational risks, reduce weather-related disruptions, and improve overall airport safety and efficiency.
Our portfolio includes both Low-Level Wind Shear Alert Systems (LLWAS-3) and state-of-the-art Lidar-based wind shear detection systems, offering complementary capabilities for comprehensive coverage.
The LLWAS-3 system is a ground-based network of strategically positioned anemometer stations installed around the airport, particularly near runway thresholds and along approach and departure paths. Each station measures wind speed and direction in real time, transmitting data to a central processing unit. The system analyzes wind field variations across the network to detect divergence, convergence, and shear patterns. Subcomponents of LLWAS-3 include sensor towers with ultrasonic or mechanical anemometers, communication units (wired or wireless), central processors, and operator display systems. Advanced algorithms process incoming data to generate timely alerts and warnings, which are then communicated to air traffic control for dissemination to pilots.
Complementing LLWAS-3, our Lidar-based solutions utilize Doppler Light Detection and Ranging technology to remotely sense wind profiles over a wide spatial range. These systems emit laser pulses into the atmosphere and analyze the backscattered signal from aerosols to determine wind speed and direction at various altitudes and distances. Lidar systems are particularly effective in detecting microbursts, gust fronts, and complex wind structures beyond the immediate vicinity of the runway. Key components include the laser transmitter, optical receiver, scanning mechanism, signal processing unit, and advanced visualization software.
The integrated system architecture combines data from LLWAS-3 and Lidar systems into a centralized control platform, providing a comprehensive and real-time picture of wind conditions across the airport environment. The control system includes Human-Machine Interface (HMI) displays, alarm management modules, data logging and reporting tools, and interfaces for integration with ATC systems and meteorological reporting platforms.
Additional features such as automated calibration, self-diagnostics, redundancy configurations, and configurable alert thresholds ensure continuous system availability and operational reliability. The systems are designed for rugged environments, with weatherproof enclosures and low-maintenance requirements.
By combining proven ground-based sensing with advanced remote sensing technologies, our Wind Shear solutions deliver unmatched accuracy, coverage, and reliability—empowering airports to maintain the highest levels of safety and operational performance under all weather conditions.
