            NOTES:
             1.  50 FOOT (15 m) SPACING MAY BE USED WHEN LENGTH OF AREA IS
                   LESS THAN 250 FEET (75 m) IN WHICH CASE THE FIRST FULL CHEVRON
                   STARTS AT THE INDEX POINT (INTERSECTION OF RUNWAY CENTERLINE AND
               RUNWAY THRESHOLD).
             2.  CHEVRONS ARE YELLOW AND AT AN ANGLE OF 45 DEGREES TO THE
               RUNWAY CENTERLINE.
             3.  CHEVRON SPACING MAY BE DOUBLED IF LENGTH OF AREA EXCEEDS
                1000 FEET (300 m).  FEET  10

                 of supporting aircraft. These areas are marked with a 3-ft-wide stripe, as
                 shown in Fig. 8-24. Yellow color is used for these types of markings.
                 Taxiway Markings
                 Taxiway markings consist of centerline markings, holding position
                 markings, and often edge markings. Taxiways are marked as shown in
                 Fig. 8-25.

                 Centerline and Edge Markings
                 The centerline of the taxiway is marked with a single continuous 6-in
                 yellow line. On taxiway curves, the taxiway centerline marking con-
                 tinues from the straight portion of the taxiway at a constant distance
                 from the outside edge of the curve. At taxiway intersections which
                 are designed for aircraft to travel straight through the intersection,
                 the centerline markings continue straight through the intersection. At
                 the intersection of a taxiway with a runway end, the centerline stripe
                 of the taxiway terminates at the edge of the runway.
                    At the intersection between a taxiway and a runway, where the
                 taxiway serves as an exit from the runway, the taxiway marking is usually
