FLIGHT TEST OF DIAMOND AND OTHER PROPORTIONED RUNWAY PAINT MARKINGS FOR GLIDE SLOPE GUIDANCE

摘要

The glide slope guidance value of three patterns of specially proportioned paint markings on the approach end of a small airport runway was evaluated in a flight test which also included approaches using a red/white VASI and approaches using only normal visual cues. Both private and professional pilots were instructed to approach on a glide slope such that the special paint markings, a diamond, an ellipse, or a pair of rectangles, appeared square or of equal dimensions in length and width. Results indicated that approaches made with the specially proportioned paint markings were similar to approaches made using only normal cues.
