When the eye is posi-

tioned on a 3

° 

glide 

slope at the slant 

range distances indi-

cated with white run-

way markings on a 

black runway sur-

face, 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

Light point size should 

be measured using 

a test pattern con-

sisting of a centrally 

located single row of 

light points reduced 

in length until modu-

lation is just discern-

ible in each visual 

channel. A row of 48 

lights will form a 4

° 

angle or less.
