title: Testing method of plus and minus Gz tolerance at Czech Air Force pilots.
abstract: Pilots' physiological measurement in conditions of alternating plus and minus Gz (gravitational acceleration) has been done during real flights. The comparison of physiological responses during flights at the safe altitude of 7000 ft and low level flights at the altitude of 900 ft over ground bears on the evaluation of changes of the continuous blood pressure and the heart rate. High level of pilots' plus-minus Gz tolerance is essential requirement to cope with low level flights in agile aircraft. It was proved that the sinusoidal profile during real flights is possible to use for pilots' tolerance to plus and minus Gz load evaluation. A system for the physiological signal acquisition in a cockpit of combat aircraft was developed for this purpose.
