Abstract : A summary is presented of what is known and not known about visual factors in the contact analog flight display. The review is an attempt to call attention to existing criteria for making such decisions insofar as they depend on pilot perceptual factors and indicate whether such criteria rest on empirical, rational, or intuitive grounds. The style is discursive and the content speculative rather than conservative for it is felt that this is the only way that will permit a full discussion of the problem. The discussion is the synopsis of a process lasting from 1954 to the present. A version of the contact analog pilot display is shown. The broad checkered surface is a flat horizontal surface, like the ground. The ladder-like ribbon represents the command path for the pilot -- the director highway down which he should be flying. The circular objects represent flat objects lying in a cloud-like plane. All of these surfaces respond to all degrees of freedom of motion of the aircraft and when the aircraft is in motion, it is as though the pilot were looking out at a world of checkered earth, ladder-like highways and flat circular clouds.
