Airport Weather Advisor® (AWA) is a complete, integrated software solution for automated weather observation systems at airports worldwide. AWA combines sensor integration, intelligent data processing, automated reporting, and flexible distribution into a single platform purpose-built for aviation weather monitoring, meeting the requirements of ICAO Annex 3 for automated meteorological observing systems and supporting international airports with Category I, II, and III instrument approach and landing operations.

System Architecture

• Outdoor Airfield Station: Collects and verifies sensor data before transmission; customizable sensor suite equipped with barometer, wind speed/direction, temperature, relative humidity, visibility, precipitation, cloud height, present weather, thunderstorm, freezing rain, and weather camera sensors
• Indoor Central Processing Station: Processes sensor data into accurate weather observation reports, archives data, and serves as the hub for user interaction and dissemination
• AWOS Live (Secure Cloud Platform): Enables 24/7 remote monitoring, giving pilots and staff real-time access to weather data and system diagnostics from any screen, plus an AWOS Live Weather Camera for real-time visual insight

Core Features

• Automated Reporting: generates METAR, SPECI, SYNOP, LOCAL, and Daily Summary reports automatically or on-demand with full FAA compliance
• Multi-Sensor Support: integrates wind, temperature, pressure, visibility, ceiling, precipitation, and lightning sensors from multiple manufacturers via serial, network, or analog I/O
• Advanced Algorithms: intelligent weather analysis including RVR calculation, present weather determination, and cloud layer assessment
• Flexible Distribution: disseminates reports via automated voice broadcast (VHF radio/ATIS), email, web interface, FTP, and direct TCP/IP connections
• Virtual Airfield Stations™: groups sensors into logical stations for runway-specific weather monitoring and tailored reporting
• Data Archiving: comprehensive logging with 90-day report retention and 35-day system event logs, with exportable archives for compliance and analysis

Weather Observation & Monitoring

• One-minute observation updates across all sensors
• ATC-ready display interface for air traffic controllers
• Raw sensor data diagnostics and health monitoring
• Present weather identification and coding
• Customizable data views for different user roles
• Configurable SPECI criteria trigger automatic special reports on significant weather changes
• Local weather alerts via email, audible alarms, and on-screen notifications

User Access & Interfaces

• Browser-based main application with full administrative capabilities (works with all major browsers)
• Web-based remote access for monitoring and basic control
• Dedicated ATC observation display for air traffic control towers
• Diagnostic terminal interface for maintenance personnel
• Role-based access control (Administrator, Observer, Viewer, etc.)

Flexible Configuration
Supports complex airport configurations with multiple runways, stations, and sensor arrays. Easily accommodates airport growth through simple device addition and configuration. Administrators can manage runway light intensity levels, configure I/O settings, and organize sensors into Virtual Airfield Stations for optimal monitoring.
