Use Of Performance Charts; Sample Problem - Cessna 1980 182Q Pilot's Operating Handbook And Flight Manual

CESSNA
MODEL 182Q
INTRODUCTION
SECTION 5
PERFORMANCE
Performance data charts on the following pages are presented so that
you may know what to expect from the airplane under various conditions,
and also, to facilitate the planning of flights in detail and with reasonable
accuracy. The data in the charts has been computed from actual flight tests
with the airplane and engine in good condition and using average piloting
techniques.
It
should be noted that the performance information presented in the
range and endurance profile charts allows for 45 minutes reserve fuel at
the specified cruise power. Fuel flow data 'for cruise is based on the
recommended lean mixture setting. Some indeterminate variables such as
mixture leaning technique, fuel metering characteristics, engine and
propeller condition, and air turbulence may account for variations of
100/0
or more in range and endurance. Therefore, it is important to utilize all
available information to estimate the fuel required for the particular
flight.
USE OF PERFORMANCE CHARTS
Performance data is presented in tabular or graphical form to illus-
trate the effect of different variables. Sufficiently detailed information is
provided in the tables so that conservative values can be selected and used
to determine the particular performance figure with reasonable accuracy.
SAMPLE PROBLEM
The following sample flight problem utilizes information from the
various charts to determine the predicted performance data for a typical
flight. The following information is known:
