Introduction; Use Of Performance Charts; Sample Problem - Cessna 150 COMMUTER 1977 Pilot Operating Handbook

CESSNA
MODEL 150M

INTRODUCTION

Performance data charts on the following pages are presented so
that you may know what to expect
conditions, and
with reasonable accuracy. The data in the charts has been computed
from actual flight tests with the
and using average piloting techniques.
It should be noted that the performance information presented in
the range and endurance profile charts allows
fuel based on 45% power. Fuel flow data for cruise is based on the
recommended lean mixture setting.
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
important to utilize all available information
required for the particular flight.

USE OF PERFORMANCE CHARTS
