After
The
emergency
static air source is designed to provide a
source of static pressure to
the
instruments
from
inside
the
fuselage should
the
outside static air ports become blocked.
An abnormal reading of the
instruments
supplied
with
static air could indicate a
restriction
in
the
outside
static
air
ports. A lever on the
lower
sidewall
adjacent to
the
pilot, is
placarded
OFF NORMAL, ON EMERGENCY.
When
it is
desired or required to use
this
alternate
source of
static
air,
select
the
ON EMERGENCY position. To recognize
the
need
and procedures for the use of emergency
static
air,

PRESSURE
SYSTEM
Pressure for the
flight
instruments,
deice boots, and
auto-
pilot
(if installed) is supplied by
two,
engine-driven,
dry,
pressure pumps interconnected to
form
a single system. If
either
pump
fails, check valves
automatically
close and
the
remaining
pump
continues
to operate all gyro
instruments.
A pressure gage on the
instrument
panel
indicates
pres-
sure
in inches of mercury. Two red
buttons
on
the
pressure
gage serve as source
failure
indicators, each
for
its respec-
tive side of the system. The .pressure system
incorporates
two
filters
per engine. One is located on
the
rear
baffle
of
the engine to
filter
intake air to the pressure pump. The
other
is
down
stream of the
pump
and is located
aft
of the
firewall
in the upper nacelle. This
filter
protects
the
instru-
ments.
