Multiply 3,226 L X 0.84 = 2.709.8 L, multiply 2
crew X 7.2 LPM = 14.4 LPM, multiply 1 passenger
X 3.7 LPM, add 14.4 LPM crew plus 3.7 LPM
passenger = 18.1 LPM. Divide 3,226 L by 18.1
LPM = 178.2 minutes.

windshield wipers, are provided for use at all flight
speeds. The rotary switch (fig. 2-13) placarded
WINDSHIELD WIPER, located in 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 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 in the overhead circuit breaker
panel (fig. 2-6).
Do not operate windshield wipers on
dry glass. Such action can damage
the linkage as well as scratch the
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.
For ferry purposes, a forward facing chair may be
attached to the floor tracks at fuselage station 211.87.
CIGARETTE LIGHTERS AND ASH TRAYS.
The pilot and copilot have individual cigarette lighters
and ash trays mounted in escutcheons out-board of their
seats. The cigarette lighters are protected by a 5-
ampere circuit breaker, placarded CIGAR LIGHTER, on
the overhead circuit breaker panel (fig. 2-6).
a. Description. A side-facing, chemical toilet is
installed in the aft cabin area and can also be used as
an additional seat. 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
