Abstract : The activities of the controllers from three centers were compared to determine the effects of Positive Control on air traffic controllers. Every observable activity of each of the controllers was recorded during periods of high activity. Each sector was analyzed by combining recordings from direct observation with analyses of tape recordings of all communications. The findings are summarized as follows: (1) Although the number of aircraft being controlled was higher and each of the aircraft received more service than under Traditional Control, Positive Control did not significantly increase the controllers' communication workload. (2) The amount of coordination required by Conventional Positive Control was somewhat higher. (3) The beacon hand-offs were considerably more efficient than the radar hand-offs in terms of the amount of time they required. (4) The comparison of two Positive Control systems data indicates that the tracker position may not be essential. An analysis of activities of the tracker indicates that many of these manual functions may be adequately performed by mechanical tracking devices that are presently available as ''off-the-shelf'' items.
