What is the standard lateral separation for aircraft operating less than 50 miles from the monitoring antenna?

The amount of lateral separation you use depends on how well the surveillance system can track aircraft at that range. Close to the monitoring antenna, radar coverage is more precise, so pilots can be kept safely apart by three miles laterally. This three-mile rule applies when aircraft are within about 50 miles of the radar, assuming both are radar-identified and in the same coverage area. As you move farther from the antenna, tracking becomes less precise, so larger separations are used to maintain safety, which is why beyond that range you’d typically see an increased minimum. Therefore, three miles is the correct standard for aircraft operating within 50 miles of the monitoring antenna.
