Wanted. 100% capacity pressure
at known temperature.

Method. Move left along 100% line
to -30C line and move down to 1420 PSIG.
2-62. WINDSHIELD WIPERS.
windshield wipers are provided for use at all flight
speeds. A rotary switch (fig. 2-15) placarded
WINDSHIELD WIPER, located on the overhead control
panel, selects mode of windshield wiper operation. An
information placard above the switch states: DO NOT
OPERATE ON DRY GLASS. Function positions of the
switch, as read clockwise, are placarded: PARK - OFF -
SLOW - FAST. When the switch is held in the spring-
loaded PARK setting, the blades will return to their
normal inoperative position on the glass, then, when
released, the switch will return to the 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. 2-9).
Do not operate windshield wipers on
dry glass. Such action can damage
the linkage as well as scratch the
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. FERRY CHAIR.
For ferry purposes, a forward facing chair is provided
that may be attached to the floor tracks at fuselage
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. 2-9).
2-65. CHEMICAL TOILET.
Description. A side-facing chemical toilet which
can also be used as an additional seat is installed in the
aft cabin area. Two hinged-lid half-sections must be
raised to gain access to the toilet. Waste is stored within
a removable container located below the seat in the
cabinet assembly. This non-flushing system uses a dry
chemical preparation to deodorize the stored waste. A
toilet tissue dispenser is contained in a slide-out
compartment on the forward side of the toilet cabinet. A
box of disposable waste container liners and a box of
chemical deodorant packets are also stored in the
Operation. During use, a removable throwaway
plastic liner is attached to the waste container. After
use, dry chemical deodorant obtained from the storage
cabinet is deposited on the waste and the hinged lid
sections are closed over the cavity. After each flight, the
waste container must be removed, emptied, relined, and
replaced in the cabinet. Consumable toilet items should
be resupplied as needed.
2-66. SUN VISORS.
When adjusting the sun visors, grasp
only by the top metal attachment to
avoid damage to the plastic shield.
Individual sun visors are provided for the pilot and
copilot (fig. 2-10). Each visor is manually adjustable.
When not needed as a sun shield, each visor may be
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.
The relief tube is located immediately aft of the
cargo door on the left side of the fuselage.
