[The effect of mobility of the information field of the helmet-mounted indicator on pilot's efficiency].
Results of an experimental investigation of pilot's efficiency with the use of a helmet-mounted indicator (HMI) are reported. Displacement of the HMI information field in consequence of head movements in search for external objects and target acquisition was shown to impact reliability of spatial orientation and cause difficulties during construction and realization of aircraft control movements. These difficulties are ascribed to impairment of functioning of the human "body scheme" (internal systems of coordinates) and modification of the geometric relations of the true and HMI displayed horizon. The conclusion is that to improve efficiency of pilots using HMI designed should be a device which will align the HMI information field with the longitudinal cabin axis after each head movement.
