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.
