  f. Runway Side Stripe Marking. Runway side                dimensions disposed symmetrically about the
stripes delineate the edges of the runway. They             runway centerline, as shown in FIG 2-3-1, or the

abutting terrain or shoulders. Side stripes consist of      indicated in TBL 2-3-2. A threshold marking helps
continuous white stripes located on each side of the        identify the beginning of the runway that is available

der stripes may be used to supplement runway side                                   TBL 2-3-2
