This volume contains the proceedings of the Thirteenth Annual Conference on Manual Control held at the Massachusetts Institute of Technology at Cambridge from June 15 to 17, 1977. This report contains complete manuscripts of most of papers presented at the meeting. This was the thirteenth in the series of conferences dating back to December 1964. The proceedings volume showed much progressed in the growth and understanding of target tracking, flight maneuvers, performance, attention allocation pilot models and mental load. The conference was planned to represent the general field of surface vehicle control and monitor behavior and supervisory control. Manipulators, Prosthetics, aerospace vehicle control, motion and visual cues were also discussed. This symposium reflected the large amount of work that has been done on pilot control signals, iterative technique for flight director design and acquisition of control information in a wind shear.
