Abstract : A simulation study was made to determine a pilot's ability to establish a specific glide path angle by perceiving the apparent squareness of an oblong diamond mark on a runway. Twenty subjects were asked to say when they perceived squareness of the diamond marks. The subject's task was to adjust a movable simulated runway, which sloped upward or downward from level, changing the perspective of the marks until the first diamond mark in the runway centerline appeared to be square. The median viewing angle of each subject's judgments was his score. Two diamond center-lines of different dimensions were simulated: one with diamonds 10 feet wide by 75 feet long, and another with diamonds 10 feet wide by 150 feet long. (Author)
