3-D Weather Displays for Aircraft Cockpits.
Abstract
The purpose of this study was to examine the effects of dimensionality and rotating frame of reference in a weather avoidance task. Forty student pilots, performed a 3-D route planning task to navigate around weather formations and arrive at a target within an airspace. The subjects were randomly blocked into four groups, each of which used all four of the display types (3-D rotating, 3-D fixed, 2-D rotating, and 2-D fixed) in varying orders. The subjects performed ten trials for each display type. The results indicated that the 2-D and rotating displays supported navigation through a shorter radial distance, and the 2-D displays also resulted in faster weather planning times. This additional distance and time is attributed to the ambiguity within the 3-D displays. There was no significant difference found between the displays in terms of vertical distance traveled, penetrations of the weather formations, number of vectors created, or the evaluation of situational awareness.
