The purpose of the study was to determine the feasibility of using the Computing Devices of Canada, Ltd. Spectocom Head-Up Display in a helicopter for instrument landing approaches. The first phase examined IFR landing approach performance with the display in the fixed-wing design configuration. No other flight displays were presented. The second phase examined the same maneuver with the display augmented with heading information. Test conditions included full VFR, simulated intermittent IFR and simulated full IFR. The test vehicle was an Army OH-13K Bell helicopter. Six rated and highly experienced helicopter pilots participated as test subjects. Results indicated that, when the display was used in the configuration designed for fixed wing, lateral flight path control was poor and IFR landing approaches were unacceptable. When heading information was added satisfactory approaches were made to a break-out altitude of 100 feet. Author
