N/A ...........................

The ratio is calculated by dividing
the brightness level of the center, bright square (providing at
least 2 foot-lamberts or 7 cd/
m2) by the brightness level of
any adjacent dark square.

X

Measurements may be
made using a 1Section spot
photometer and a raster
drawn test pattern filling
the entire visual scene
(all channels) with a test
pattern of black and
white squares, 5 per
square, with a white
square in the center of
each channel. During
contrast ratio testing,
simulator aft-cab and
flight deck ambient light
levels should be zero.

4.d. ........................

Highlight brightness .......

Not less than three (3) foot-lamberts (10 cd/m2).

N/A ...........................

Measure the brightness of the
center white square while
superimposing a highlight on
that white square. The use of
calligraphic capabilities to enhance the raster brightness is
acceptable, but measuring light
points is not acceptable.

Measurements may be
made using a 1Section spot

4.e. ........................

Surface resolution .........

Not greater than two (2) arc minutes.

N/A ...........................

An SOC is required and must include the relevant calculations.

X

When the eye is positioned
on a 3Section glide slope at the
slant range distances indicated with white runway markings on a black
runway surface, the eye
will subtend two (2) arc
minutes: (1) A slant
range of 6,876 ft with
stripes 150 ft long and 16
ft wide, spaced 4 ft apart.
(2) For Configuration A; a
slant range of 5,157 feet
with stripes 150 ft long
and 12 ft wide, spaced 3
ft apart. (3) For Configuration B; a slant range of
9,884 feet, with stripes
150 ft long and 5.75 ft
wide, spaced 5.75 ft
apart.
