Measurement was made of the ability of a group of helicopter pilots to perform simulated rotary wing maneuvers under three instrument display conditions which augmented the JANAIR contact analog vertical display with numeric information. Moving tape scales, moving pointer scales and digital readouts, each presented with the basic grid plane were compared with each other and the basic grid plane alone. The numeric information displayed included indices of altitude, heading and airspeed. The display conditions were tested under 1 a relatively stable cruise task and 2 a variable terrain following task. Measures of altitude control, airspeed control, heading control and appropriate collective control inputs were recorded. Results indicate that numeric information significantly enhanced performance when presented in conjunction with the contact analog and that the moving tapes and the moving pointers each produced significantly better performance scores than the digital readouts. These results were consistent in both helicopter tasks tested. Author
