What kind of signal does STARS send after processing the DASR output?

The correct answer indicates that STARS (Standard Terminal Automation Replacement System) transmits electronic data streams after processing the DASR (Digital Audio Switching Router) output. This is essential because STARS is designed to enhance the efficiency and effectiveness of air traffic operations by providing a seamless flow of data among various components of the air traffic control system.

The use of electronic data streams allows for the integration of multiple data sources and the sharing of critical information, improving situational awareness for air traffic controllers. It ensures that information regarding aircraft positions, weather, and other relevant factors is delivered in real time, thus facilitating informed decision-making and effective communication between controllers and pilots.

In contrast, options like audio alerts, video only, or visual displays and reports focus on specific formats of information presentation. While these may play a role in the overall system, they do not encompass the comprehensive and integrated nature of electronic data streams, which are key to the operational capabilities of STARS.
