Aviation mishaps resulting from degraded visual environments DVEs cause a significant loss in military personnel and aircraft every year. DVEs are considered to be any type of environmental condition e.g., fog, blowing sand or snow that reduces visibility and can cause the loss of spatial orientation. For helicopters, DVEs are often created by the aircraft rotor downwash recirculating sand or snow while hovering or during landings. This report describes new techniques for testing and validating sensory cueing displays to aid helicopter flight in DVEs. Research through a tri-service effort will be using the approaches reported here to investigate the advantages of utilizing spatialized auditory cues for locating and tracking objects outside the aircraft during simulated helicopter flight when there is an obstructed field of view. Application of these techniques will provide critical proof-of-concept information on sensory cueing displays for helicopter flight in DVEs.
