In order to conduct helmet-mounted display (HMD) helicopter research flights in daylight, two versions of a simulated degraded visual environment (SDVE) were developed. SDVE-1 consisted of a tailored fire-retardant black cloth hood that is draped over the pilot's helmeted head and ventilated with a standard personal ventilator. While SDVE-1 successfully eliminated troublesome reflections, improved display readability, and was reasonably comfortable, pilots reported disturbing sensations of sensory deprivation and isolation. SDVE-2 combined colored filters on the hood and helicopter windscreen to allow the pilot a view of the cockpit interior while blocking light from the external environment. This system has been well accepted and has facilitated safe in- flight HMD research. Motion sickness remains an issue in HMD flight performance research.
