Abstract:

Four predictive ground collision avoidance displays Break-X, Chevrons Mountain, and Highway were tested using a fixed-base T-38 simulator with a projection screen and simulated Head-Up Display HUD. The Break-X was similar to the conventional military alert except that it remained on the screen until the aircraft was recovered to safety. The Chevron display consisted of two caret symbols which slid horizontally inward as danger increased, forming an X identical to the break-X. The Mountain display used a single icon which moved upward in the HUD as danger increased, mimicking the motion of the terrain outside. The Highway was a preview display, which consisted of a perspective elevated surface shown at the desired altitude.
