Accuracy of Visually Perceived Roll Angle and Roll Rate Using an Artificial Horizon and Peripheral Displays

摘要

In computer controled ground tests, jet transport pilots were required to make accurate and fast estimates of roll attitude or roll rate presented at short intervals on a central cathode ray tube display (artificial horizon). The influence of exposure time and, in the case of the roll rate perception task, the influence of the presence of displays in the peripheral field of vision, were investigated. Results show that roll attitude perception is more accurate and can be accomplished at much shorter exposure times than roll rate perception. Reaction time for roll attitude perception is 0.1 sec shorter than for roll rate perception using the central display. Peripheral displays improve roll rate perception and decrease reaction time.
