Abstract:

The use of a motion simulator in the evaluation and testing of display and instrumentation concepts which are central to the objectives of the Army-Navy Instrumentation Program ANIP poses the same question, to what extent does the device allow a valid evaluation of the developments under consideration. The ultimate in validity would be achieved when operator behavior in the simulator corresponds precisely to control behavior in the system being simulated which, in this case, is a helicopter in all of its flight modes. Since it is unrealistic to expect exact behavior correspondence in the two situations the task is one of determining the extent or degree of approximation. This report summarizes the results of a series of three investigations, both simulator and flight test, designed to determine the relative proficiency allowed by motion information in the simulator in a hovering flight mode and, secondly, to determine with appropriate measures the degree to which control behavior in the helicopter is approximated by behavior in the simulator when the tasks are equivalent. The proficiency results are reported in terms of integrated absolute error scores about the various axes defining the hovering task, and the behavioral data, are presented in the form of auto-correlation functions.
