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

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

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