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 aircrait. With the Flight Guide, you can easily take into account
temperature variations from standard at any flight altitude.
