Modern fighter pilots are often exposed to excessive accelerations. The resulting brain hipoxia can lead to G-LOC (G-induced loss of consciousness). Authors discuses the effects of microcirculatory adaptation released by the push-pull condition (rapid change from minus to plus Gz). The memory effect of vaso-pull condition (rapid change from minus to plus Gz). The memory effect of vaso-constriction due to - Gz can be responsible for intermittent blocking of the compensatory vasodilatation and diminishing the +Gz tolerance of pilots tested on the centrifuge. Authors consider the push-pull condition to be analogous to the rapid blocking of the brain perfusion caused by the high plus Gz onset rates (1,G/s). Using the visual symptoms (narrowing of the visual field) is not longer adequate for monitoring the centrifuge push-pull trainig. Authors discuses the possibility of using the saccadic eye movements as being the most adequate physiological signal to monitor the pilot's consciousness. Measuring pilots eye movements requires to develop a miniature complex motion transducer which can be used during centrifuge training as well as during the flight (the White Box). Problems encountered during the system development are discussed.
