Participants judged whether the perceived touchdown point was above or below a probe that appeared at a random position following each display. Although judgments were unacceptably imprecise and biased for moving dot and runway displays, accurate and unbiased judgments were found for griddisplays. It is concluded that optic flow per se does not appear to be sufficient for a pilot to land an airplane and …
