When a receptive strategy was adopted, i.e., little control exerted over the acceptance rates, a slight reduction in the scatter of the distribution of arrivals at the pickup is noted, compared with a regulative strategy. Fewer holding procedures at the outer stacks, a higher average number of aircraft within the control area and on the extended runway centerline, and the need for holds at the inner stacks also result. The ensuing higher traffic density in the approach control area created difficult initial conditions for sequence planning. Control is affected more by the working techniques of individual controllers than by traffic flow. 收起
