The complexity of total traffic phenomena in a controlled airspace is described by a model that relates the variables of the traffic number of aircraft, distribution, speed, the rules of operation separation minima and the airspace volume and flow organization to the load which is imposed on the control position of the sector. Basic units of control load and control work are defined and used for quantification of the control effort required. The relationship between the load imposed on the control position and the geometry and the orientation of the sector is demonstrated and a method for optimizing the design of the sector is analyzed and described in a numerical example. The control capacity is quantified in units of control load and method of matching the size of the sector to the capacity for maximum efficiency of sector design is demonstrated and discussed. A paired comparison study is used to scale the amount of control work involved in handling the traffic in each of 20 control problems.
