The functional and behavioral requirements for a visual flight research facility (VFRF) emphasize visual and motion simulation but include performance assessment, laboratory calibration, and control and test station requirements. Information collected from special helicopter flights at NOE altitudes, pilot interviews, analysis of relevant data, and review of other pertinent research facilities was used in engineering analyses and trade-off studies to determine specific performance values and alternative facility concepts. Eight alternative facility configurations and capabilities were considered, including simulation of a day-and-night (color) capability or a monochrome night capability. A night visual display system with sensor aiding was selected because it represented the most cost-effective approach to an acceptable range of high-priority, night NOE studies in the earliest time frame. The pilot's night vision capability along with ways to improve his performance and increase his survivability, represents a most critical NOE problem. Low-cost sensor aids and techniques would permit wide utilization by present and planned helicopters. 收起
