ABSTRACT
The article deals with results of experimental studies conducted on flight testing desk and covering peculiarities of pilot's perception of flight information presented on on-board liquid crystal display in dependence on changes speed and update rate of the screen. The authors determine frequency characteristics of information update rate, that achieve acceptable quality of the flight parameters perception in accordance with the changes speed. Vigorous maneuvering with high angular velocities of changed parameters of roll and pitch causes visual distortions that are connected with poor frequency of information update rate, deteriorate piloting quality and can cause flight unsafety.

The influence of long (up to 5 min) flying overloads with moderate values (2-5 U, at the increase and descent rate of 0,6-1,5 U/s) on the functional state and activities of airplane crewmembers was studied during the real flights. It was established that the influence of such overloads causes the unfavorable changes in the functional state and decrease in the effectiveness of crewmembers' (especially of a navigator-operator) actions. It was shown that the use of measure complex (during the flight the crewmembers use anti-overload dress, the pilot informs the navigator-operator about beginning of maneuvering, trainings on statoergometer to improve the crewmembers' static physical endurance) allows increasing the crews' psychophysiologic capacity during the maneuvers accompanied with the effect of complex flying overloads with moderate values.

The use of a rational (geocentric) method of orientation in flight is determined by the specific content of the conceptual model that develops in the course of flying experience and by the display of the spatial position of perceptive signs of the geocentric system of coordinates. The importance of these factors is confirmed by erroneous decisions made by operators with no flying experience (40%) when they estimated the spatial position as well as by a shorter time and a lower number of errors made in assessing the spatial position when the display presented signs of the geocentric system of coordinates.
