dc.description.abstractAn analysis of the gravitational and inertial forces which act during aircraft flight upon the vestibular systems of the aircraft occupants reveals that in the absence of a visual horizon, certain illusory sensations are predictable for various acceleration environments. Horizontal forward applied acceleration results in a climbing (backward tilting) sensation; conversely, horizontal rearward applied acceleration results in a diving (forward tilting) sensation. During any attempt to achieve weightlessness in aircraft parabolic flight, special care has to be taken to avoid unintended longitudinal ( x -axis) accelerations. Recent flight tests established that the ‘rotation sensation’ (Dzendolet, 1971; Gerathewohl, 1956) during entry into parabolic flight can be attributed to the existence of unintended longitudinal accelerations. However, the ‘inversion illusion’ (Graybiel and Kellogg, 1966) felt by some human subjects at 0 g seems to be different from the rotation sensation and could be caused by the diminished pressure forces of the otoliths on the maculae. The ‘inversion illusion’ of man correlates well with the blind fish diving behavior observed during aircraft parabolic flight (von Baumgarten et al. , 1969, 1972). It is suggested that the fish low g diving response and the human inversion illusion are due to the substitution of a predominately shearing force of low magnitude as a vestibular reference in place of a normal, predominately pressure force. This hypothesis indicates that vestibular senses alone cannot provide meaningful postural orientation to simulated or actual gravity of a magnitude below that of Earth's gravity.en_US
