Predictor Displays for Low-Altitude High-Speed Flight.
Abstract
Three fixed-based simulation studies were conducted to determine the applicability of the predictor display concept to Low Altitude High Speed (LAHS) information display. Only pitch axis information (three degrees of freedom) was considered. Three airspeeds--Mach 0.6, 0.9, and 1.2--were used in all three studies. A preliminary study was conducted to determine appropriate display scale factors. Using a fixed prediction span of 10 seconds, vertical scale factors of 250, 500, and 1,000 ft/cm and horizontal scale factors of 2,000, 4,000, and 6,000 ft/cm were evaluated. A vertical scale of 500 ft/cm and a horizontal scale of 2,000 ft/cm were selected for further studies. The first experimental study compared pilot performance using a predicted flight-path display with pilot performance without a predicted flight-path display. The second experimental study investigated the effect of prediction span on pilot performance. Spans of 0.25 sec, 3.5 sec, and 6.75 sec were evaluated. (Author)
