Light point size ..............

Not greater than five (5) arc-min-

utes.

N/A ...........................

An SOC is required and must in-

clude the relevant calculations.

X  Light point size may be 

measured using a test 
pattern consisting of a 
centrally located single 
row of light points re-
duced in length until 
modulation is just dis-
cernible in each visual 
channel. A row of 48 
lights will form a 4

° 

angle 

or less.

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

A 1

° 

spot photometer may 

be used to measure a 
square of at least 1

° 

filled 

with light points (where 
light point modulation is 
just discernible) and 
compare the results to 
the measured adjacent 
background. During con-
trast ratio testing, simu-
lator aft-cab and flight 
deck ambient light levels 
should be zero.
