Abstract : A basic assumption underlying a contact analog display is that such a display will transmit information to the pilot in a manner which embodies the necessary and sufficient cues resident in the real world. Most pilots receive this information from a stimulus complex based upon experience of binocular vision. However, when presenting information in an analog form on a display within the cockpit, the necessary three-dimensional information must currently be presented on a two-dimensional surface. This restricts the observer to monocular cues for judging depth and distance. This experiment was designed to compare the performances of experienced helicopter pilots in howering the helicopter on contact under conditions of binocular and monocular vision. It further compared these performances under two sizes of viewing area full contact visibility and an 8 x 8 in. viewing port. Hovering data were collected on eight United States Army helicopter trainees having 35 to 40 hr fixed-wing time and an average of 80 hr helicopter time. The parameters recorded were altitude, lateral and fore and aft translation. The data were reduced to a constant error statistic and a variability statistic. (Author)
