Surface contrast ratio. 

Not less than 5:1. 

N/A

.........................................

The ratio is calculate

d 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.

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.
