Aircraft operating at 50 miles or more from the monitoring antenna shall be separated by a minimum of?

When radar surveillance distance increases, the accuracy of the position information drops. To keep pilots and the controller safe despite that reduced reliability, the separation requirement is raised for aircraft that are 50 miles or more from the monitoring antenna. Five miles provides a bigger safety margin to account for potential position errors, data latency, and tracking uncertainties that become more likely at long range. That’s why the minimum separation at that distance is five miles.
