What is the name of the bird hazard notification system based on a network of NEXRAD radars?

The Avian Hazard Advisory System (AHAS) is designed to provide real-time information about bird movements in specific areas based on data from a network of NEXRAD radars. By utilizing advanced radar technology, AHAS monitors bird activity and generates alerts when significant migrations or flocks are detected, effectively assisting pilots and air traffic controllers in making informed decisions to mitigate the risk of bird strikes.

AHAS is particularly valuable in the context of aviation safety as it allows for timely notifications regarding avian activity, potentially leading to adjustments in flight paths or operational procedures to avoid hazardous encounters. The system integrates NEXRAD radar data to provide a comprehensive view of bird activity, enhancing awareness and safety in airspace where bird strikes may occur.

The other options, while related to avian hazards, do not specifically represent the NEXRAD-based notification system that is central to AHAS's functionality. For instance, the Bird Strike Hazard System is not a recognized title, the Bird Avoidance Model (BAM) serves a different purpose primarily focused on predictive modeling rather than real-time advisories, and BIRDNET, while it sounds relevant, does not denote the specific system referenced in the question.
