4-4.2.1
Place a light where the line of threshold lights intersects the line of runway
edge lights. Then place lights at 1.5 meters (5 feet) for a distance of 12 meters (40 feet)
outboard of the runway edge light lines.
4-4.2.2
Place lights at uniform intervals between the lines of runway edge lights
and along the line of the threshold lights. Space as near to 1.5 meters (5 feet) as
possible and do not exceed 1.55 meters (5 feet 2 inches). The line of threshold lights
may be gated to lessen the problem of tail hook bounce by eliminating those lights in
the center 21-meter (70-foot) portion of the threshold, but must be waived by the major
command. Note that blank covers must be flush with the runway surface.
