OPERATIONAL
DATA
The
operational data shown
on
the following pages
are
compiled from
actual tests with the
aircraft
and engine in good condition and using
aver-
age piloting technique.
You
will find this data a valuable aid when
plan-
ning
your flights.
A power setting selected from the range
chart
usually will be
more
efficient than a random setting, since it will permit you to
estimate
your
fuel consumption-more accurately.
You
will find that using the
charts
and
your Power Computer will pay dividends
in
overall efficiency.
Cruise and range performance shown in
tlµ.s
section
is
based
on
the
use of a McCauley 1Cl60/DTM7553 propeller
and
a standard equipped
Skyhawk.
Other conditions for the performance data
are
shown in the
chart headings. Allowances for fuel reserve, headwinds, take-off and
climb,
and
variations in mixture leaning technique should be made and
are
in
addition to those shown
on
the chart. Other indeterminate
variables
such
as
carburetor
metering characteristics, engine and
propeller
condi-
tions, externally-mounted optional equiJEllent and turbulence of the atmo-
sphere may account for variations of
10%
or
more
in
maximum range.
Remember that the
charts
contained herein
are
based
on
standard day
conditions.
For
more
precise
power, fuel consumption, and endurance in-
formation, consult the Cessna Power Computer supplied with your
air-
craft.
With
the Power Computer,
you
can easily take into account
temper-
ature variations from standard
at
any flight altitude.
