PERFORMANCE
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 using average piloting techniques and an airplane
and engine in good condition and equipped with a
Hartzell propeller.
Airplanes equipped with a
McCauley propeller will have comparable
performance and should also use the data shown.
WARNING
TO ENSURE THAT PERFORMANCE IN
THIS SECTION
CAN BE DUPLICATED, THE AIRPLANE AND ENGINE
MUST BE MAINTAINED IN GOOD CONDITION. PILOT
PROFICIENCY AND PROPER PREFLIGHT PLANNING
USING DATA NECESSARY FOR ALL FLIGHT PHASES
IS ALSO REQUIRED TO ASSURE EXPECTED
PERFORMANCE
WITH AMPLE MARGINS OF SAFETY.
It should be noted that the performance information presented in the
rage and endurance profile charts allows for
45
minutes reserve fuel at
the specified cruise power and altitude. Some indeterminate variables
such as 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.
Notes have been provided on various graphs and tables to
approximate performance with the inertial separator in BYPASS
andlor
cabin heat on. The effect will vary, depending upon airspeed,
temperature, and altitude. At lower altitudes, where operation on the
torque limit is possible, the effect of the inertial separator will be less,
depending upon how much power can be recovered after the separator
vanes have been extended.
In some cases, performance charts in this section include data for
9
temperatures which are outside of the operating limits (Figure
5-5).
This
data has been included to aid in interpolation.
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.
