Abstract: An evolutionary analysis of display-control systems in aircraft guidance reveals four major categories. 1. Manual Systems The most primitive category involves the exclusive use of direct visual contact with objects external to the aircraft viewed through the wind-screen (see Fig. 1A). In this situation the operator relies primarily on his ability to perform visual judgments of idstance, size, motion, shape, and the position of various objects relative to the pilot’s “visual world” (1). In addition, the pilot relies heavily on kinesthetic and vestibular cues; that is, he flies “by the seat of his pants.” The major limitations of this display mode relate to, first, the inherent errors present in all subjective visual judgments (2), and, second, the frequent obstruction of visual contact resulting from adverse environmental conditions.
