Abstract : The design study was conducted by HEL to standardize collective-stick controls in U.S. Army helicopters. The objective was to formulate a standard which will specify functions and arrangement of switches on collective-stick controls in Army helicopters. Two types of collective-stick controls were developed to meet requirements in all categories of helicopters designed for the U.S. Army. A human factors engineering (HFE) evaluation was done by HEL on functional hard mock-up models representing the general design configuration developed for standardization of collective-stick controls. Results of the HFE test indicate that the configurations developed for standardization is suitable for developing airworthy designs for flight test. (Author)
