Airport Marking Aids and Signs

FIG 2−3−23

Helicopter Landing Areas

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 Para-

graph 2−3−8, Mandatory Instruction Signs, through

Paragraph 2−3−13, Runway Distance Remaining

Signs.
