Visual perception during flight is influenced to a considerable degree by angular acceleration and by increased 'g'. Studies of the visual illusions reported by subjects observing an isolated target in the dark, show marked illusions of motion and displacement during and following turns. The flight paths described by the aircraft in these turns were executed by means of a constant power setting and a change in the angle of attack of the wing. The result was a change in the direction of the g force to a maximum of approximately 12 during 60 degrees banks as the angle of attack increased. The purposes of the present study were: (1) to determine what illusory effects occur when the resultant g force is increased but kept in a constant direction in relation to the otolith organ, and (2) to obtain data on the occurence of habituation since there is evidence that this phenomenon does occur in certain situations involving rotation.
