MARKINGS
f. Surface Painted Location Signs.
Surface painted location signs have a black background with a yellow
inscription. When necessary, these markings are used to supplement location signs located along side 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. (See FIG 2
11.)
g. Geographic Position Markings.
These markings are located at points along low visibility taxi routes
designated in the airport’s Surface Movement Guidance Control System (SMGCS) plan. They are used to
identify the location of taxiing aircraft during low visibility operations. Low visibility operations are those that
occur when the runway visible range (RVR) is below 1200 feet (360m). They are positioned to the left of the
taxiway centerline in the direction of taxiing. (See FIG 2
12.) The geographic position marking is a circle
comprised of an outer black ring contiguous to a white ring with a pink circle in the middle. When installed on
asphalt or other dark-colored pavements, the white ring and the black ring are reversed (i.e., the white ring
becomes the outer ring and the black ring becomes the inner ring). It is designated with either a number or a
number and letter. The number corresponds to the consecutive position of the marking on the route.
