AC No: 150/5340-1M.pdf

The Federal Aviation Administration (FAA) issued Advisory Circular (AC) 150/5340-1M, which contains standards for markings used on airport runways, taxiways, and aprons. The AC provides guidelines for uniform application of airfield surface markings and is voluntary, except for projects funded under Federal grant assistance programs or the Passenger Facility Charge program. The AC incorporates principal changes, including new criteria for centering runway landing designators, definitions, and recommendations for training personnel. It also revises text and figures to clarify functions and applications of various markings, such as no-taxi islands and approach/departure holding position markings. A change to the AC, dated 12/23/2020, updates implementation procedures for approach/departure holding positions and delays implementation of conditional marking and associated signage until the FAA updates relevant aeronautical publications.
