position on the glass, then, when released, the switch
will return to OFF position terminating windshield wiper
operation. The FAST and SLOW switch positions are
separate operating speed settings for wiper operation.
The windshield wiper circuit is protected by one 10-
ampere circuit breaker, placarded WSHLD WIPER,
located on the overhead circuit breaker panel (fig. 2-
27).
CAUTION
Do not operate windshield wipers
on dry glass. Such action can
damage the linkage as well as
scratch the windshield glass.
b.
Normal Operation. To start, turn WINDSHIELD
WIPER switch to FAST or SLOW speed, as desired. To
stop, turn the switch to the PARK position and release.
The blades will return to their normal inoperative
position and stop. Turning the switch only to the OFF
position will stop the windshield wipers, without returning
them to the normal inactive position.
2-63. MISSION OPERATOR SEATS.
The mission operators are each provided with a
cushioned chair-type seat. The seats are individually
located on floor-mounted seat tracks and may be
positioned to face forward or aft. The seats are
adjustable forward and aft by removing the seat track
pins, repositioning the seat, then reinstalling the seat
track pins. Each mission operator seat is equipped with
a lap-type seat belt and shoulder harness connected to
an inertia reel. The shoulder harness belt is of the "Y"
configuration with the single strap being contained in an
inertia reel attached to the base of the seatback. The
two straps are worn with one strap over each shoulder
and fastened by metal loops into the seat belt buckle.
The spring loading at the inertia reel keeps the harness
snug but will allow normal movement required during
flight operations. The inertia reel is designed with a
locking device that will secure the harness in the event
of sudden forward movement or an impact action.
2-64. CIGARETTE LIGHTERS AND ASH TRAYS.
The pilot and copilot have individual cigarette
lighters and ash trays mounted in escutcheons outboard
of their seats. The cigarette lighters are protected by a
5-ampere circuit breaker, placarded CIGAR LIGHTER,
on the overhead circuit breaker panel (fig. 2-27).
2-65. ELECTRIC TOILET.
a.
Description. An electric toilet is installed in the
aft cabin area. The circuit is protected by a 10-ampere
circuit breaker located in the power distribution panel
under the floor ahead of the main spar.
b.
Operation. A switch, placarded PRESS TO
FLUSH, is mounted on the seat assembly for operation
of the toilet. Pressing the switch applies DC power to
the motor which drives the pump. The pump applies
flushing fluid through a nozzle in the upper rim and
washes the inner surface of the bowl. Waste is carried
to the waste tank mounted below the bowl. When
desired, the removable waste tank may be removed
from the toilet for servicing (Section XII).
2-66. SUN VISORS.
CAUTION
When adjusting the sun visors,
grasp only by the top metal
attachment to avoid damage to
the plastic shield.
A sun visor is provided for the pilot and copilot
respectively (fig. 2-7). Each visor is manually
adjustable. When not needed as a sun shield, each
visor may be manually rotated to a position flush with
the top of the cockpit so that it does not obstruct view
through the windows.
2-67. RELIEF TUBE.
One relief tube is provided, located immediately
aft of the cabin door on the left side of the fuselage.
