ARMY-NAVY INSTRUMENTATION PROGRAM. REDUNDANCY IN THE DISPLAY OF SPATIAL ORIENTATION
Abstract
Studies were made of problems involved in extracting, presenting, and displaying analog flight attitude information to helicopter pilots. Results do not support the view that stimulus redundancy contributes significantly toperformance. Stimulus redundancy may be considered to have two aspects. The first is that of a mere combination of elements, and the second is a combination which gives rise to a new precept such as depth. The apparatus used possessed two degrees of freedom only (pitch and roll), while vertical, lateral, and longitudinal displacement and yaw were static. Secondly, the use of nonpilots may have prevented a difference between displays from emerging, since pilots are accustomed to making stick responses in the presence of a moving horizon while non-pilots are not. However, the present experimental design is justified since, if a difference had been found between displays the results would have been applicable to considerations for the design of altitude indicators. The differences, if existent, are not to be measured by the method selected. Although these results are not in agreement with those of Matheny and Hardt (ANIP Rept. no. D228-421-002), a difference could be conceivably be obtained between the two methods.
