10-2.3.2
The color(s) must be selected with consideration given to the background
and to make the indicator clearly visible and understandable from a height of at least
300 meters (1,000 feet). Where practicable, use a single color, preferably white or
orange. When a combination of two colors is required to provide conspicuity, the
preferred colors are orange and white, red and white, or black and white. The colors
must be arranged in 5 alternate bands, the first and last band being the darker.
10-2.4
Lighting Requirements
Illuminate the wind cone with floodlights which are arranged to provide a minimum
illumination level of 2 footcandles (20 lux) at any point on the horizontal plane described
by a complete rotation of the upper surface of a fully extended cone. The lights must be
shielded to prevent light emission above the horizontal. Equip the wind cone support
with an obstruction light.
10-2.5
Power Requirements
Provide a main power source only. If powered from the associated runway edge lights,
they will have the provision so the cone floodlight brightness does not vary more than
20 percent with the available light, meeting the requirements of paragraph 10-2.4, at the
lowest setting of the runway edge lights.
10-2.6
Control Requirements
On and off control is the only requirement and may be accomplished via the runway
edge light circuit if used.
10-2.7
Monitoring Requirements
There are no requirements for monitoring wind cones.
10-2.8
Equipment
The wind indicators must be as shown in paragraph 13-12.3.
10-2.9
Compliance with International Standards
There are no ASCC or NATO standards for wind indicators.
10-2.10
Additional Information
See FAA AC 150/5345-27, Specification for Wind Cone Assemblies, for additional
information.

RUNWAY AND TAXIWAY RETRO-REFLECTIVE MARKERS
10-3.1
Purpose
Reflectors and retro-reflective markers may be used to supplement existing runway and
taxiway lighting, or for temporary installations. However, a waiver must be granted by
the major command for their use.
10-3.2
Characteristics
The retro-reflective materials used are designed to reflect light approaching at an
oblique angle, back toward the light source.
