What is the preferred separation method in air traffic control?

The preferred separation method in air traffic control is radar separation because it allows for more precise tracking and management of aircraft in the skies. Radar systems provide continuous updates on the positions, speed, and altitude of aircraft, enabling air traffic controllers to maintain tighter and more efficient separation between flying aircraft. This method enhances the safety and efficiency of air traffic management, allowing for quicker responses to any potential conflicts or changes in flight paths.

In contrast, non-radar separation relies on position reports and estimated timings from pilots, which can introduce delays and increase the possibility of human error. While non-radar methods might still be necessary in certain situations, such as in remote areas without radar coverage, radar separation is generally preferred for its improved accuracy and real-time data capabilities. This allows controllers to manage air traffic more effectively, ensuring a higher standard of safety and operational efficiency.
