Under which conditions are radar separation minima increased beyond the standard values?

Radar separation minima are baseline safety distances used under normal conditions, but they can be increased when conditions affect surveillance or flight predictability. Weather and complex airspace both raise risk: weather can reduce visibility and radar performance, create unpredictable aircraft behavior, and clutter radar displays; complex airspace means more traffic, tighter routing, and more potential conflicts. In either case, adding extra margin helps ensure there’s enough time to detect and resolve potential conflicts, even if radar tracking is less reliable or aircraft trajectories are harder to predict. That’s why the correct condition is to use greater separation near weather or in complex airspace.
