RUNWAY MARKING STUDIES.
Abstract
To help evaluate the effectiveness of several different runway marking patterns under limited visibility conditions, a set of special composite photographs was prepared simulating a pilot's-eye view of the patterns from various points along the glide path. The set includes three marking patterns, the U. S. standard and two modified versions thereof, on both asphalt and concrete surfaces, as viewed under daytime visual-range conditions from 2400 ft down to 700 ft. Each of the composite photos consisted of two visual components combined through appropriate processing techniques. One component was made by photographing a 30:1 scale model runway layout in a fog chamber under a given set of conditions. The other component was taken from motion picture film showing the inside of a flight simulator cockpit as viewed from the pilot's-eye position. The contrasts in the original scenes were matched in the photographs by means of suitable photometric controls. (Author)
