OPERATIONAL DATA
The operational data shown on the following pages are compiled from
actual tests with the airplane and engine in good condition and using average
piloting technique and best power mixture. You will find this data a valuable
aid when planning 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 this section is based on the use of
a McCauley 1C160/CTM 7553 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 conditions, externally-mounted optional
equipment 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.
