[Experimental study of pilot-assisted detection of changes in the information field of the on-board view indicator]

The paper reports experimental data about the effects of operative memory restrictions on the indices of reliability of the visual identification of changes in external objects represented on the onboard visual indicator display. It was demonstrated that parallel piloting and visual tracking reduced the probability of identification of changes in two external objects up to 0.89 and deteriorated the ability to sustain the designated mode of piloting in six and more times. Two types of erroneous responses were delineated: overlooking changes in symbol-targets and false anxieties. Changes in the background symbols appeared to provoke false anxieties. The highest levels of reliability of eye tracking could be reached by changing color and/or contours of symbols-targets on the display.
