Paper Abstract

Most visual display systems for piloted simulators provide out-the-window monochromatic or chromatic scenes by means of televised views of airport models. A more recent and promising technique is the use of digital computers to generate the outside display scene. This technique has suffered, however, from limitations in perceived realism. This paper describes a calligraphic, chromatic system developed for improving the perceived realism of out-the-window display scenes, presents the results of a brief study to demonstrate such improvement, and discusses current developmental work and future research. The method selected for providing the natural color cues normally available to the pilot during a real night landing approach required the construction of a new chromatic projector for use with a calligraphic display. The chromatic projector permits (i) drawing 2000 vectors in as many as 500 colors, all above critical flicker frequencies, and (ii) using high scene resolution and brightness at an acceptable level to the pilot, within the maximum system capabilities of 1000 lines and 1000 fL (3426.26 cd/m2). In support of this new digital, calligraphic, chromatic projector system, a brief experimental investigation was performed in a fixed-base simulator to determine the effect, on system performance and pilot opinion, of a chromatic landing display as compared to that of a, monochrome display. Both performance measures and pilot opinion support the hypothesis that using a chromatic landing display improves system performance.
