Cessna 182 1973 - Flight Operations Data

ALTERNATOR
CHECK.
Prior
to
flights
where
verification
of
proper
alternator
and
voltage
regulator
operation
is
essential
(such
as
night
or
instrument
flights), a
positive
verification
can
be
made
by
loading
the
electrical
system
momen-
tarily
(3
to
5
seconds)
with
the
landing
light during
the
engine
runup
(1700
RPM).
The
ammeter
will
remain
within
a
needle
width
of
zero
if the
al-
ternator
and
voltage
regulator are
operating
properly.
TAKE-OFF.
It
is
important
to
check
full-throttle
engine
operation
early
in
the
take-
off
run.
Any
signs
of
rough
engine
operation
or
sluggish
engine
accelera-
tion
is
good
cause
for
discontinuing
the
take-off.
Full
throttle
runups
over
loose
gravel are especially
harmful
to
propeller tips.
When
take-offs
must
be made
over
a
gravel
surface,
it
is
very
important
that the
throttle
be
advanced
slowly.
This allows the
air-
plane
to
start
rolling
before
high
RPM
is
developed,
and the
gravel
will be
blown
back
of
the
propeller
rather
than
pulled
into
it.
Most
engine
wear occurs
from
improper operation
before
the
engine
is
up
to
normal
operating
temperatures,
and
operating
at
high
powers
and
RPM's.
For this
reason
the
use
of
maximum
power
for take-off
climb
should be
limited
to
that
absolutely
necessary
for
safety.
Whenever
possible,
reduce
take-off
power
to
normal
climb
power.
Normal
take-offs
are
accomplished
with
wing
flaps
0°
to
20°,
cowl
flaps
open,
full
throttle,
and 2600
RPM.
Reduce
power
to
23
inches
of
manifold
pressure
and
2450
RPM
as
soon
as
practical
to minimize
engine
wear.
Using
20°
wing
flaps
reduces
the
ground
run
and
total distance
over
the
obstacle
by approximately
20
per
cent.
Soft field
take-offs
are
per-
formed
with
20°
flaps
by
lifting
the
airplane
off
the
ground
as
soon
as
practical
in
a
slightly
tail-low
attitude.
However,
the
airplane
should
be
leveled
off
immediately
to
accelerate
to
a
safe climb
speed.
’
If
20°
wing
flaps
are
used
for
take-off,
they
should
be
left
down
until
all
obstacles
are
cleared.
To
clear
an
obstacle with
wing
flaps
20
degrees,
an
obstacle
clearance
speed
of
60
MPH
should
be
used.
If
no
obstructions
are
ahead, a
best
"flaps
up''
rate-of-climb
speed
2-12
