OPERATIONAL DATA
The operational data shown on the following pages are compiled from
actual tests with airplane and engine
in
good condition, and using average
piloting technique and best power mixture. You will find this data
a
valu-
able aid when planning your flights.
To realize the maximum usefulness from your Cessna, you should
take advantage
of
its high cruising speeds. However,
if
range
is of
pri-
mary importance,
it
may pay you
to fly at a
low cruising RPM, thereby
increasing your range and allowing you
to
make the trip non-stop with
ample fuel reserve.
The
range table on page 5-4 should be used
to
solve
flight planning problems
of
this nature.
In the table (figure 5-4), range and endurance are given for lean mix-
ture from 2500 feet
to
12, 500 feet.
All
figures are based on zero wind,
22. 5 and 35. 0 gallons
of
fuel for cruise, McCauley 1A100/MCM6950
propeller, 1600 pounds gross weight, and standard atmospheric conditions.
Mixture
is
leaned
to
maximum RPM. Allowances for fuel reserve, head-
winds, take-offs and climb, and variations
in
mixture leaning technique
should be made
as
no allowances are shown on the chart. Other indetermi-
nate variables such
as
carburetor metering characteristics, engine and
propeller conditions, and turbulence
of
the atmosphere 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 Flight Guide (Power Computer) supplied
with your aircraft. With the Flight Guide, you can easily take into account
temperature variations from standard
at
any flight altitude.
