How often should the radar position updates occur for effective air traffic control?

For effective air traffic control, radar position updates should occur on a continuous basis to ensure that controllers have real-time information about the location and movement of aircraft in their airspace. Continuous updates allow for timely decision-making regarding separation, conflict resolution, and the efficient management of air traffic flow. By continually monitoring radar data, controllers can promptly address any changes in aircraft positions or potential conflicts, enhancing overall safety and efficiency in airspace management.

Other time intervals, such as every 5 minutes or every 15 minutes, would not provide the necessary immediacy required for effective traffic control, especially during busy operational periods. Additionally, relying solely on updates when requested would hinder a controller's ability to manage air traffic proactively and respond to dynamic situations in real-time. Continuous updates thus play a crucial role in maintaining safety standards and operational effectiveness in air traffic control environments.
