TABLE 8-3 Striping Requirements for Runway
Threshold Markings

Runway Threshold Markings
Runway threshold markings identify to the pilot the beginning of the
runway that is safe and available for landing. Runway threshold mark-
ings begin 20 ft from the runway threshold itself.
Runway threshold markings consist of two series of white stripes,
each stripe 150 ft in length and 5.75 ft in width, separated about the
centerline of the runway. On each side of the runway centerline, a num-
ber of threshold marking stripes are placed, in accordance with the width
of the runway, as specified in Table 8-3. Table 8-3 specifies the total
number of runway threshold stripes required. For example, for a 100-ft
runway, eight stripes are required, in two groups of four are placed about
the centerline. Stripes within each set are separated by 5.75 ft. Each set of
stripes is separated by 11.5 ft about the runway centerline.
The above specifications for runway threshold markings were
adapted by the FAA from ICAO international standards and made
mandatory for United States civil use airports in 2008.

Centerline Markings
Runway centerline markings are white, located on the centerline of
the runway, and consist of a line of uniformly spaced stripes and gaps. The
stripes are 120 ft long and the gaps are 80 ft long. Adjustments to the
lengths of stripes and gaps, where necessary to accommodate runway
length, are made near the runway midpoint. The minimum width of
stripes is 12 in for visual runways, 18 in for nonprecision instrument
runways, and 36 in for precision instrument runways. The purpose of
the runway centerline markings is to indicate to the pilot the center of the
runway and to provide alignment guidance on landing and takeoff.

Aiming Points
Aiming points are placed on runways of at least 4000 ft in length to
provide enhanced visual guidance for landing aircraft. Aiming point
markings consist of two bold stripes, 150 ft long, 30 ft wide, spaced
