VISUAL RUNWAY MARKINGS

f. Runway Side Stripe Marking.

Runway side stripes delineate the edges of the runway. They provide a

visual contrast between runway and the abutting terrain or shoulders. Side stripes consist of continuous white
stripes located on each side of the runway as shown in FIG 2

4.

g. Runway Shoulder Markings.

Runway shoulder stripes may be used to supplement runway side stripes

to identify pavement areas contiguous to the runway sides that are not intended for use by aircraft. Runway
shoulder stripes are yellow. (See FIG 2

5.)

h. Runway Threshold Markings.

Runway threshold markings come in two configurations. They either

consist of eight longitudinal stripes of uniform dimensions disposed symmetrically about the runway centerline
(as shown in FIG 2

3

1) or the number of stripes is related to the runway width as indicated in TBL 2

2. A

threshold marking helps identify the beginning of the runway that is available for landing. In some instances,
the landing threshold may be relocated or displaced.
