Runway Markings Familiarization

MARKING COLOR
All runway markings are white except for runway intersection hold short markings, taxiway lead in lines that extend onto the runway, taxiway centerlines that lead off the runway, and runway
shoulder markings (chevrons); if present.

RUNWAY DESIGNATOR
Runway numbers and letters are determined from the approach direction. The runway numbers
nearest one-tenth the magnetic azimuth of the centerline of the runway, measured clockwise from magnetic north.

RUNWAY CENTERLINE MARKING
The runway centerline identifies the center of the runway and provides alignment guidance during takeoff and landings. The centerline consists of a line of uniformly spaced stripes and gaps.

RUNWAY AIMING POINT MARKING
The aiming point marking serves as a visual aiming point for a landing aircraft. These two
rectangular markings consist of a broad white stripe located on each side of the runway centerline and approximately 1,000 feet from the landing threshold.

RUNWAY TOUCHDOWN ZONE MARKERS
The Touchdown Zone markings identify the TDZ for landing operations. TDZ markings are coded to provide distance information in 500 feet increments. These markings consist of groups of one, two, and three rectangular bars symmetrically arranged in pairs about the runway centerline.

RUNWAY SIDE STRIPE MARKING
Runway side stripes delineate the edges of the runway. They provide a visual contrast between
runway and abutting terrain or shoulders. Side stripes consist of continuous white stripes located
on each side of the runway.

RUNWAY SHOULDER MARKINGS
Runway shoulder stripes may be used to supplement runway side stripes in identifying pavement areas contiguous to the runway sides that are not intended for use by aircraft. Runway shoulder markings are yellow.

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, or the number of stripes related to the runway width.

CHEVRONS
These markings are used to show pavement areas aligned with the runway that is unusable for
landing, takeoff, and taxiing. Chevrons are yellow.
