How frequently must ATC evaluate traffic situations?

ATC must evaluate traffic situations continuously to ensure the safety and efficiency of air traffic operations. This ongoing assessment allows air traffic controllers to remain aware of any changes in aircraft positions, flight paths, and potential hazards in real time. Continuous evaluation is crucial as it enables timely responses to dynamic situations, such as aircraft deviations, changes in weather conditions, and emergency scenarios.

Maintaining continuous situational awareness is vital for preventing collisions, managing airspace congestion, and facilitating safe landings and takeoffs. The nature of air traffic control requires that controllers actively monitor and assess traffic at all times, rather than relying on fixed intervals or shifts. This constant vigilance enhances overall safety and operational efficiency in the busy skies.
