The rapid development of aviation technology entails the need to increase the quality of ergonomic support. This is due to the fact that for the safe implementation of activities, the pilot has to use the entire amount of attention, not rarely, at the limit of his capabilities. The color of the instrument scales, the contrast of the information feed, and other information perception conditions can significantly complicate the evaluation of the flight instrument readings. This is especially true with the transition of most modern aircraft from analog display of instrument readings to digital. The study examines the features of perception of digital information by operators of aviation profile with different color background of the stimulus material. The analysis of the results of the solution by operators of 3 Schulte tables and 3 SchultePlatonov tables on the combined hardware complex NS-Psychotest with the system of fixing the coordinates of the eye-stationary eye tracking RED250mobile eye tracking device. When performing the eye search function, the number of visual fixations and the task completion time were calculated. It was found that when searching for digital values on Schulte tables with a white background, the number of eye fixations was less than when performing a similar task on black-and-red SchultePlatonov tables. Accordingly, it also took less time to solve black-and-white tables. A trend was found showing that the search for digital values represented in the SchultePlatonov tables on a red background was carried out by operators faster than on a black background. Further study of this topic can contribute to the development of proposals for ergonomic support of aircraft, which in turn will help to maintain the reserves of attention of operators in a continuous stream of incoming data (2 figures, 1 table, bibliography: 13 refs).
