General Description

ICAO Approach Light
The Crouse-
Hinds ICAO Approach Light is a Style II, (≤1/2 inch) fixture that meets the
photometric requirements of ICAO Annex 14 fixtures 2.1, 2.2, 2.3, 2.4, and 2.8 with the
appropriate lamp(s) and colored lens/lenses installed. It is designed for installation at the
runway threshold or any other location where visual guidance of moving aircraft is desirable.
The fixture is designed to fit on a FAA L-868 (do not install on shallow base), steel, size B
light base per FAA AC 150/5345-42 (latest version), and have a total height above
grade/ground level of
<
.500 inch. The fixture is uni-directional, projecting the beam of light
in one direction or bi-directional when used as a threshold wingbar or siderow light with a red
end light. It is weatherproof and will endure roll over loads without damage. The light fixture
consists of a 1-piece aluminum optical assembly. The aluminum optical assembly is mounted
to a light base with six bolts and six 2-piece lock washers. The aluminum housing has a sand
cast bottom cover that is attached using 6 screws. A silicone o-ring is used to provide a
watertight seal between the inner cover and the optical housing. The lamp(s) are secured to an
installed bracket, which is fastened to the bottom housing using vibration isolators. Electrical
connections are made at one or two feed-thru assemblies in the inner cover. The feed-thru has
an ITS verified L-823 plug for connecting to FAA L-830/ L-831 Isolation Transformers. The
outer lens is held into the aluminum housing with a bracket, gasket, molded elastomeric boot
and 2 screws. The light beam color is obtained by coloring the lens to the appropriate color
for the application. All hardware is type 18-8 stainless steel. The complete light unit is 11.94
inches in diameter, 5.13 inches deep, and weighs 16 lbs
.
CAUTION
CAUTION:
Never handle the light assembly by the leads as this can break the
waterproof seal.
