The investigation tested a model which hypothesizes that the critical visual cue for control of a helicopter is the relationship between a fixed internal referent placed on the helicopter windscreen and an external referent placed on the ground plane. To investigate the likelihood that a pilot could maintain vehicular control through detecting changes in the inter-referent distances, both laboratory and field experiments were designed. The laboratory investigation was concerned with verifying the Weber ratio. The field investigation was devised to permit the filming of pilots' eye movements and measurement of system performance in three translational degrees of freedom during hovering flight.
