Introduction; Use Of Performance Charts; Sample Problem - Cessna 182T 2001 Pilot Operating Handbook

CESSNA
MODEL 182T

INTRODUCTION

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 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 at all altitudes. Some
indeterminate variables such as mixture leaning technique, fuel
metering characteristics, engine and propeller condition, and air
turbulence may account for variations of 10% or more in range and
endurance. Therefore, it is important to utilize all available
information to estimate the fuel required for the particular flight and
to flight plan in a conservative manner.

USE OF PERFORMANCE CHARTS

Performance data is presented in tabular or graphical form to
illustrate 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. Assume the following information has already been
determined:
