of 89
MPH would be
most
efficient,
These speeds
vary
slightly with:
altitude,
but they
are
close enough
for average
field elevations.
Flap
deflections
greater
than
20°
are
not recommended
at
any
time for take-
off.
Take-offs into
strong crosswinds
normally
are performed
with the
minimum flap setting
necessary for
the field length, to minimize the
drift
angle immediately
after
take-off.
The
airplane is accelerated to
a speed
slightly higher than normal, then pulled
off
abruptly to
prevent possible
settling
back to
the
runway while
drifting.
When
clear
of
the ground, make
a coordinated
turn
into the
wind
to
correct for drift.
ENROUTE
CLIMB.
A
cruising
climb
at
23
inches
of
manifold
pressure,
2450
RPM (ap-
proximately
75%
power)
and 100
to
120 MPH
is
recommended to save time
and fuel
for
the
overall trip.
In addition,
this
type
of
climb
provides bet-
ter
engine cooling,
less
engine wear,
and
more passenger
comfort
due
to
lower noise level.
:
If
it
is
necessary
to climb
rapidly
to
clear
mountains or
reach favor-
able winds at high
altitudes,
the
best rate-of-climb
speed should
be
used
with maximum power, This speed
is
89
MPH
at
sea
level,
decreasing
2
MPH for each
5000
feet
above
sea level.
If
an
obstruction
ahead
requires
a
steep
climb angle,
the
airplane
should be flown
at
an obstacle
clearance
speed
of
approximately
70
MPH
with flaps
up
and maximum power,
CRUISE.
Normal
cruising
is
done
between
65%
and
75%
power.
The
power
settings required
to
obtain
these
powers
at various altitudes
and outside
air
temperatures
can be
determined
by
using your
Cessna
Power Com-
puter
or the OPERATIONAL
DATA,
Section
VI.
The Maximum
Cruise
Speed
Performance
table (figure 2-5) shows
that cruising
can
be done
most efficiently at higher
altitudes
because
very nearly
the same
cruising
speed can
be
maintained
at
much
less
power.
