4.c. ..............

Surface contrast ratio. 

Not less than 5:1. 

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

The ratio is calculated by di-

viding the brightness level 
of the center, bright square 
(providing at least 2 foot- 
lamberts or 7 cd/m

2

) by the 

brightness level of any ad-
jacent dark square. 

X  Measurements may be made 

using a 1

° 

spot photometer 

and a raster drawn test 
pattern filling the entire vis-
ual scene (all channels) 
with a test pattern of black 
and white squares, 5 per 
square, with a white square 
in the center of each chan-
nel. During contrast ratio 
testing, simulator aft-cab 
and flight deck ambient 
light levels should be zero. 

4.d. .............

Highlight brightness. 

Not less than six (6) foot-lam-

berts (20 cd/m

2

). 

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

Measure the brightness of 

the center, white square 
while superimposing a 
highlight on that white 
square. The use of calli-
graphic capabilities to en-
hance the raster brightness 
is acceptable; however, 
measuring light points is 
not acceptable. 

X  Measurements may be made 

using a 1

° 

spot photometer 

and a raster drawn test 
pattern filling the entire vis-
ual scene (all channels) 
with a test pattern of black 
and white squares, 5 per 
square, with a white square 
in the center of each chan-
nel.
