CORTEX LLWAS
Low Level Windshear Alert System for real-time detection of windshear and microbursts, providing audible and visual ATC warnings with location, intensity and headwind-impact information for safer airport operations.
Typical Applications
- Airport low-level windshear monitoring
- Microburst detection
- Runway approach and departure safety
- Air Traffic Control weather alerting
- Multi-runway wind-monitoring networks
- Thunderstorm and convective weather operations
- Coastal airports affected by sea-breeze windshear
- Mountainous airports with terrain-induced windshear
The CORTEX LLWAS Low Level Windshear Alert System provides real-time detection and warning of windshear, microbursts, wind gusts and rapid wind-direction changes during critical aircraft takeoff and landing operations. Using the proven NCAR Phase III detection algorithm, the system analyzes data from distributed airport wind-monitoring stations and delivers immediate audible and visual alerts to Air Traffic Control (ATC), including information about the event’s location, intensity and operational headwind impact.
Key Features
- Real-time low-level windshear detection
- Microburst detection and warning
- Wind-gust and sudden-direction-change monitoring
- Proven NCAR Phase III detection algorithm
- Real-time audible ATC alerts
- Graphical visual alert display
- Event location and intensity information
- Headwind-impact assessment
- Configurable airport wind-sensor network
- Flexible multiple-runway coverage
- Single and redundant configurations
- ICAO and WMO recommendation compliance
- FAA-certified detection algorithms
- Designed around airport-specific terrain and runway geometry
Unlike a single wind sensor, LLWAS compares measurements across a distributed airport sensor network, enabling the system to identify dangerous localized wind changes and determine where a windshear or microburst event is affecting an aircraft’s approach or departure path.
