Taxiway Centerline Width

7. Taxiway and Apron Markings.

7.1. Taxiway and taxi lane Centerline Stripe. Mark the centerline of all taxiways, guidelines on runways, and taxi lanes on aprons and pads with a single continuous 152-millimeter (6-inch) wide yellow stripe.

Deceptive Markings

9.3.2. Taxiway and Apron Shoulders. Mark deceptive surfaces on the edges of taxiways and aprons with perpendicular stripes as shown in Figure 18. These markings consist of a series of 914-millimeter (3-foot) wide stripes positioned perpendicular to the edge markings. On curves, a stripe is placed at each point of tangency and intermediate stripes are spaced uniformly up to 9 meters (30 feet) apart. Figure 18 shows the dimensions and spacing of the stripes. Stripes are located so that the inner edge of the marking is coincident with the edge of the full-strength pavement.

VFR/INST Runway Holding Position

7.2 Both VFR and instrument holding positions are marked from edge to edge of the pavement surface, including paved shoulders.

7.2.2.1. This hold position is configured differently from a VFR hold position and is augmented with the letters "INST" on the runway side of the line. The letters are to be read when facing the runway. They are marked in block letters 1829 millimeters (6 feet) high by 610 millimeters (2 feet) wide, spaced 305 millimeters (1 foot) apart. The letters are formed with a 152-millimeter (6-inch) stroke. The "INST" designator must be placed symmetrically between the taxiway centerline and the taxiway edge or edge marking on the left side of the centerline. For hold lines over 61 meters (200 feet) long, mark the "INST" designator at intervals not exceeding 45.7 meters (150 feet).

Taxiway/lane/track Edge Stripes

7.3.2. This marking consists of two 152-millimeter (6-inch) wide broken stripes separated by a gap 152 millimeters (6 inches) wide.
