Assuapt tons
a
Enemy (2 ¢9¢4 «411 rely primarily on celestial and/er radar xeans
for savisation but electronic emissions and surface lighting could
be used to ancraase the accuracy of attack.
b
The exrent of control of electronics emissions will be such as
to satisfy the fLoilowing conditions:
(1) Degree of protection to be gained must be greater than the
cost of controls.
(2) Controls will be imposed on all types of non-essential esis-
sions.
¢.
The ampertance of black 1., dimout and camouflaze has been :¢-
daced by the developments an electronics devices and bombing techniques so that total blackout is no longer justified.
¢@.
The geographical and meteorological characteristics of the 1szand posations tend to nullify the effects of electronic and surface
wichting deception.
