Research into methods by which highly maneuverable advanced helicopters can be made to function - with reasonable pilot workload levels - as stable platforms for target designation andor weapon delivery at night and in adverse weather is a major interest of the U.S. Army Aeromechanics Laboratory. Two candidate techniques under investigation are 1 helicopters control system modifications that alter the aircrafts response to pilot control inputs and to external inputs such as turbulence and 2 variations in the methods of which critical information is displayed to the pilot in an attempt to reduce the effort required to interpret and respond to a given situation while still maintaining a satisfactory level of system performance. In support of this research, a piloted simulator experiment was designed and conducted to assess the effects on overall system performance and pilot workload of variations in control system characteristics and display format and logic for a nighttime attack helicopter mission. This paper describes the experiment and presents major results and conclusions. Author
