Aircraft Provided Positive control with all other radars shall be separate by a minimum of how many miles?

Radar-based positive control relies on a safe lateral buffer between aircraft to account for radar measurement errors, update rates, and pilot/aircraft response time. Five miles is the standard minimum separation in this context because it provides a reliable margin for detecting and resolving potential conflicts without unnecessarily limiting airspace. Lower separations, like two or three miles, would reduce safety margins and risk conflicts given typical speeds and radar inaccuracies. A larger separation, such as six miles, would unnecessarily constrain capacity without additional safety benefits under normal operations. Therefore, five miles is the appropriate minimum.
