c. Nonmovement Area Boundary Markings.
These markings delineate the movement area, i.e.,
area under air traffic control. These markings are
yellow and located on the boundary between the
movement and nonmovement area. The nonmovement
area boundary markings consist of two yellow
lines (one solid and one dashed) 6 inches (15cm) in
width. The solid line is located on the nonmovement
area side while the dashed yellow line is located on
the movement area side. The nonmovement
boundary marking area is shown in FIG 2−3−21.

d. Marking and Lighting of Permanently
Closed Runways and Taxiways. For runways and
taxiways which are permanently closed, the lighting
circuits will be disconnected. The runway threshold,
runway designation, and touchdown markings are
obliterated and yellow crosses are placed at each end
of the runway and at 1,000 foot intervals.

e. Temporarily Closed Runways and Taxiways.
To provide a visual indication to pilots that a runway
is temporarily closed, crosses are placed on the
runway only at each end of the runway. The crosses
are yellow in color. (See FIG 2−3−22.)
1. A raised lighted yellow cross may be placed
on each runway end in lieu of the markings described
in subparagraph e,Temporarily Closed Runways and
Taxiways, to indicate the runway is closed.
2. A visual indication may not be present
depending on the reason for the closure, duration of
the closure, airfield configuration and the existence
and the hours of operation of an airport traffic control
tower. Pilots should check NOTAMs and the
Automated Terminal Information System (ATIS) for
local runway and taxiway closure information.
3. Temporarily closed taxiways are usually
treated as hazardous areas, in which no part of an
aircraft may enter, and are blocked with barricades.
However, as an alternative a yellow cross may be
installed at each entrance to the taxiway.
f. Helicopter Landing Areas. The markings
illustrated in FIG 2−3−23 are used to identify the
landing and takeoff area at a public use heliport and
hospital heliport. The letter “H” in the markings is
oriented to align with the intended direction of
approach. FIG 2−3−23 also depicts the markings for
a closed airport.
2−3−7. Airport Signs
There are six types of signs installed on airfields:
mandatory instruction signs, location signs, direction
signs, destination signs, information signs, and
runway distance remaining signs. The characteristics
and use of these signs are discussed in paragraph
2−3−8, Mandatory Instruction Signs, through
paragraph 2−3−13, Runway Distance Remaining
Signs.
