AIRPLANE
&
SYSTEMS DESCRIPTION
CHT
signals
are
generated
from a thermistor probe screwed
into_
the cylinder
head of
the number 1 (right
hand
fori¡vard)
cylinder. Thel
resistance
of the
probe changes
in
proportion
to the
temperature,
and is registered
on
the indicator as a
change
in
temperature.
The
engine-driven mechanical
tachometer
is
located on
the rightl
side of the pilot's
instrument panel.
The
instrument
is
marked
in
increments
of
100 RPM, and indicates both engine and
propeller
speed.
An
hour meter
in the
lower section
of the
dial
records
elapsed engine
time
in
hours
and
tenths. lnstrument
markings
include
the
normal operating range (green arc)
of
2000
lo
24OO
RPM, and a maximum (red line) of
2400
RPM.
The
manifold pressure gauge
is
part of the
manifold pressure-
gauge/fuel
flow
indicator located
on the left
side
of the
pilot'sl
instrument panel.
The
gauge
is
direct
reading
and
indicates
induction
air
manifold pressure
in inches of mercury. lt has a
normal
operating range (green arc)
of
15
to
23 ln.
Hg.
The fuel flow.
indicator
is a fuel
pressure indicator
calibrated
in
flow
rate.
The
fuell
pressure
is
taken
at
the flow
divider
valve by a
pressure transducer.
The
pressure transducer receives
a
constant voltage
from
the
indicator and returns a variable voltage depending on the
pressure,
as pressure
increases,
voltage
increases. The
indicator
is
marked
in gallons per hour and has a green arc from 0
to
15 gal./hr.
There
is no red
line
or
maximum
fuelflow (pressure) limitation. There
may
be some atmospheric
conditions
that would result in fuel flow
rates
that exceed the maximum marked value on the indicator (i.e.,
very
low density altitude and full
throttle). lf
the indicator is pegged
out
because of these
conditions,
the indicator will not be
damaged, and
will return to operating
range
when the throttle is
retarded
to
cruise
power settings.
NEW
ENGTNE
BREAK-|N AND
OPERAT|ON
I
The engine
underwent
a run in at the factory and is
ready
for
the
full
range
of
use.
lt
is,
however, suggested
that
cruising
be
accomplished
a|75"/"
power
as much as practicable until a total
of
50 hours has
accumulated
or oil
consumption has stabilized.
This
will ensure proper seating
of
the
rings.
