Cessna 182 1973 - Page 83

NOTE
Operation
at
peak
EGT
is
not
authorized
for
continuous
operation,
except
to
establish
peak
EGT
for
reference
at
75%
power
or
less.
Operation
on
the
lean
side
of
peak
EGT
or
within
25°
of
peak
EGT
is
not
approved.
The
chart
on
page
7-11
should be used
to
establish
mixture
settings
in
take-off,
climb,
and
cruise
conditions.
The
yellow
index
pointer
may
be
set
at
the
reference
point,
or
to
a
specific
point
to lean
to.
It
can
be
positioned
manually
by
turning
the
screw adjustment
on
the face
of
the
instrument.
For
maximum
performance
take-off,
mixture
may
be
set
during
static
full-power
runup,
if
feasible,
or
during
the
ground
roll.
NOTE
Enrichen
mixture
during
climb if
excessive
cylinder
head
temperatures occur.
When
leaning
the mixture
under
some
cruise
conditions,
engine
roughness
may
occur
before
peak
EGT
is
reached.
In
this
case,
use
the
EGT
corresponding
to
the
onset
of
roughness
as
the
reference
point
in-
stead
of
peak
EGT.
’
Changes
in
altitude
or
power
setting
require
the
EGT
to
be
rechecked.
Mixture
may
be
controlled
in
cruise
descent,
by simply
enriching
to avoid
engine
roughness.
During
prolonged
descents,
maintain
sufficient
power
to
keep
the
EGT
needle
on
scale.
In
idle
descents
or
landing
approaches
use
full
rich
mixture. For
idle
descents
or
landing
approaches
at
high
elevations,
the
mixture control
may
be
set
in
a
position
to
permit
smooth
engine
acceleration
to
maximum
power.
