What is the primary responsibility of the radar team regarding Mode 3/A radar beacon codes?

The primary responsibility of the radar team regarding Mode 3/A radar beacon codes is to continuously monitor codes assigned within their area of responsibility. This constant monitoring is crucial for maintaining situational awareness and ensuring the safety and efficiency of air traffic operations. By keeping track of the assigned codes, controllers can effectively identify and engage with aircraft, facilitating seamless communication and coordination in the airspace they manage.

Continuous monitoring allows radar controllers to detect any discrepancies, such as an aircraft that fails to squawk the correct code or one that appears to be in distress. It ensures that they can respond promptly to any changes in an aircraft's status, enhancing safety throughout the controlled airspace.

This ongoing vigilance is essential, especially when managing multiple aircraft simultaneously, as it helps in maintaining orderly traffic flow and preventing potential conflicts. The other options suggest either limited monitoring or an incorrect application of the codes, which would not serve the necessary responsibilities of air traffic management effectively.
