ANTICOLLISION LIGHT SYSTEM
Description
The anticollision light system includes two anticollision
lights, each controlled by an associated switch. One
anticollision light is at the top of the pylon at sta. 594
and the other anticollision light is on the helicopter
bottom centerline at sta. 290. Two ANTI-COL switches,
TOP and BOTTOM, on the overhead panel turn their
respective lights on or off.
Operation
1.
Power for the anticollision lights comes from the
28 volt No. 2 dc bus. When ANTI-COL TOP
LIGHTING circuit breaker is closed, 28 vdc is
applied to terminal 2 of TOP ANTICOL switch.
When ANTI-COL BOT LIGHTING circuit breaker
is closed, 28 vdc is applied to terminal 2 of
BOTTOM ANTI-COL switch.
2.
When TOP ANTI-COL switch is at ON, 28 vdc
from the switch operates the top anticollision
light. When BOTTOM ANTI-COL switch is at
ON, 28 vdc from the switch operates the bottom
anticollision light.
