Head-Up Display Symbology for Ground Collision Avoidance

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.
