(See FIG 2-3-3.) When a threshold is relocated, it closes not only a set portion of the approach end of a runway, but also shortens the length of the opposite direction runway. Sometimes construction, maintenance, or other activities require the threshold to be relocated towards the rollout end of the runway. In some instances, the landing threshold may be relocated or displaced. A threshold marking helps identify the beginning of the runway that is available for landing. They either consist of eight longitudinal stripes of uniform dimensions disposed symmetrically about the runway centerline (as shown in FIG 2-3-1) or the number of stripes is related to the runway width as indicated in TBL 2-3-2. Runway threshold markings come in two configurations. Runway shoulder stripes may be used to supplement runway side stripes to identify pavement areas contiguous to the runway sides that are not intended for use by aircraft. Side stripes consist of continuous white stripes located on each side of the runway as shown in FIG 2-3-4. They provide a visual contrast between runway and the abutting terrain or shoulders. Runway side stripes delineate the edges of the runway. Nonprecision Instrument Runway and Visual Runway Markings For runways having touchdown zone markings on both ends, those pairs of markings which extend to within 900 feet (270 m) of the midpoint between the thresholds are eliminated. These markings consist of groups of one, two, and three rectangular bars symmetrically arranged in pairs about the runway centerline, as shown in FIG 2-3-1. The touchdown zone markings identify the touchdown zone for landing operations and are coded to provide distance information in 500 feet (150m) increments. 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, as shown in FIG 2-3-1, Precision Instrument Runway Markings. The aiming point marking serves as a visual aiming point for a landing aircraft. The centerline consists of a line of uniformly spaced stripes and gaps. The runway centerline identifies the center of the runway and provides alignment guidance during takeoff and landings. The letters, differentiate between left (L), right (R), or center (C) parallel runways, as applicable: The runway number is the whole number nearest one‐tenth the magnetic azimuth of the centerline of the runway, measured clockwise from the magnetic north. Runway numbers and letters are determined from the approach direction. The markings and signs described in this section of the AIM reflect the current FAA recommended standards. Pilots may also report these situations to the FAA regional airports division. These situations may also be reported under the Aviation Safety Reporting Program as described in paragraph 7-7-1, Aviation Safety Reporting Program. Pilots who encounter ineffective, incorrect, or confusing markings or signs on an airport should make the operator of the airport aware of the problem. Pilots are encouraged to work with the operators of the airports they use to achieve the marking and sign standards described in this section. Uniformity in airport markings and signs from one airport to another enhances safety and improves efficiency. Airport Marking Aids and SignsĪirport pavement markings and signs provide information that is useful to a pilot during takeoff, landing, and taxiing.
