radar control : ウィキペディア英語版 | radar control Radar control is a method of providing air traffic control services with the use of radar and Automatic Dependent Surveillance (ADS-B). The provision of air traffic control services without the use of radar is called procedural control. ==Separation== In air traffic control, the risk of aircraft colliding is managed by applying separation rules. These rules require aircraft to be separated by either a minimum vertical distance, or, if for some reason they cannot be separated vertically, by a minimum horizontal distance defined by various means. One of the means of determining horizontal separation is by a controller observing the radar returns of the aircraft to be at least a minimum horizontal distance apart. This is the essence of radar control, and is known as Radar separation. Standard radar separation varies from airspace to airspace and country to country, however 3 nms in terminal airspace and 5 nms in en route airspace are common minima.
