Abstract:

New concepts in HUD symbology, based on an understanding of the physiological mechanisms and ecological origins of the human visual system are described which may enable future HUD displays to serve as primary flight directors in addition to their current roles. The four key elements of this new symbology are a prioritization of space according to the three-dimensional structure of visual attention, b an attitude display in the form of a global percept c effective preattentive attitude cueing based on an ecologically valid simulation of the visual terrain during flight and d visual reference framing which depicts the roll of the aircraft relative to a stable horizon. Prototypes which illustrate the physiological HUD concept are presented. The specific advantage of the proposed symbology may be to allow the pilot to maintain effective attitude control while directing his attention towards the out-the-window environment.
