What is the primary function of STARS?

The primary function of STARS, which stands for Standard Terminal Automation Replacement System, is to receive output from Digital Airport Surveillance Radar (DASR) and convert that data for display to air traffic controllers. This system plays a crucial role in ensuring that the radar information received is accurately processed and presented in a way that is understandable and actionable for air traffic management. By converting the raw radar data into a visual format, STARS enables controllers to effectively monitor and manage the flow of air traffic in terminal areas, enhancing safety and efficiency.

Other functions or systems mentioned in the incorrect options do not align with the specific capabilities and intended purpose of STARS. For instance, converting video feeds into audio signals or managing flight schedules and bookings pertains to different technological areas not associated with STARS. Meanwhile, controlling weather data dissemination involves different operational systems focused on meteorological information rather than radar data management, making B the most accurate and relevant description of STARS' function.
