ANTICOLLISION LIGHTS
Anticollision lights are installed on top of the
vertical stabilizer and on the bottom of the
fuselage (Figure 3-11). The lights are con-
trolled by a BCN LT switch. Each light is a
dual-bulb light, and each bulb oscillates 180°
at 45 cycles per minute. The beam is concen-
trated by an integral lens, and an illusion of
90 flashes per minute occurs due to the oscil-
lation. The lights operate on DC power through
the BCN LT circuit breaker.
WING INSPECTION LIGHT
(OPTIONAL)
A light is installed on the right side of the
fuselage adjacent to the lower forward corner
of the emergency exit window. This light is de-
signed to illuminate the leading edge of the
right wing. The light may be installed as part
of the emergency lighting system. The WING
INSPECTION control switch is located on the
emergency lighting panel.
Models 23, 24, 24B, and 25 airplanes vary to
some extent in the location of switches and
power source for some lighting. The switch for
the center panel and baggage compartment
lights is on the aft side of the cabin door and
is powered by the DOOR ACT circuit breaker.
