Analysis of Efficiency of Pilot's Behavior in Condition of Visual Illusion of False Horizon

This study examined efficiency of pilots' behavior in condition of visual illusion od false horizon. It has been assumed that visual illusion of false horizon tends to produce spatial disorientation. Efficiency of execution of flight's profile in conditions of spatial disorientation was analyzed in context of FDI. Additionally, efficiency of attention and working memory were analyzed. 29 pilots participated in the experiment (air-raid 1229, 14 hours +/- 844,26; age 32,97; +/- 6,56). Efficiency of execution of flight profile has been defined on simulator YAPETUS based on indicators of course - variability of rate. Styles of perception, efficiency of attentions and efficiency of working memory were researched by means of computer tasks. It appears that false horizon illusion influence the efficiency of pilot's behavior. In conditions of cognitive conflict: visual field - navigational instruments, younger pilots and pilots with FINT style of perception (mobile FD and fixed FI), lower efficiency of selective and divided attention, less resistance to distraction, weak mechanism of inhibition and lower efficiency of updating working memory, were most strongly exposed to disorientation.
