Enhanced Centerline The enhanced taxiway center line marking consists of a parallel line of yellow dashes on either side of the taxiway centerline. Taxiway centerlines are enhanced for 150 feet (46 m) before a runway holding position marking. The enhanced taxiway centerline is standard at all FAR Part 139 certified airports in the USA. Taxiway Edge Markings Used to define the edge of the taxiway when the edge does not correspond with the edge of the pavement. Continuous markings consist of a continuous double yellow line, with each line being at least in width, spaced apart. They divide the taxiway edge from the shoulder or some other abutting paved surface not intended for use by aircraft. Dashed markings define the edge of a taxiway on a paved surface where the adjoining pavement to the taxiway edge is intended for use by aircraft, e.g. an apron. These markings consist of a broken double yellow line, with each line being at least in width, spaced apart (edge to edge). These lines are 15 feet (4.6 m) in length with 25 foot (7.6 m) gaps. Taxi Shoulder Markings Taxiways, holding bays, and aprons are sometimes provided with paved shoulders to prevent blast and water erosion. Shoulders are not intended for use by aircraft, and may be unable to carry the aircraft load. Taxiway shoulder markings are yellow lines perpendicular to the taxiway edge, from taxiway edge to pavement edge, about 3 metres. Surface Painted Taxiway Direction Signs Yellow background with a black inscription, provided when it is not possible to provide taxiway direction signs at intersections, or when necessary to supplement such signs. These markings are located on either side of the taxiway. Surface Painted Location Signs Black background with a yellow inscription and yellow and black border. Where necessary, these markings supplement location signs located alongside the taxiway and assist the pilot in confirming the designation of the taxiway on which the aircraft is located. These markings are located on the right side of the centerline. Geographic Position Markings These markings are located at points along low visibility taxi routes (when Runway visual range is below 1200 feet (370 m)). They are positioned to the left of the taxiway centerline in the direction of taxiing. Black inscription centered on pink circle with black inner and white outer ring. If the pavement is a light colour then the border is white with a black outer ring. Runway Holding Position Markings These show where an aircraft should stop when approaching a runway from a taxiway. They consist of four yellow lines, two solid and two dashed, spaced six or twelve inches (15 or 30 cm) apart, and extending across the width of the taxiway or runway. The solid lines are always on the side where the aircraft is to hold. There are three locations where runway holding position markings are encountered: Runway holding position markings on taxiways; runway holding position markings on runways; taxiways located in runway approach areas. Holding Position Markings for Instrument Landing System (ILS) These consist of two yellow solid lines spaced two feet (60 cm) apart connected by pairs of solid lines spaced ten feet (3 metres) apart extending across the width of the taxiway. Holding Position Markings for Taxiway/Taxiway Intersections These consist of a single dashed line extending across the width of the taxiway. Surface Painted Holding Position Signs Red background signs with a white inscription to supplement the signs located at the holding position. ဆိုင်းများ မီး ကိုးကား
