PERFORMANCE
DEMONSTRATED
OPERATING
TEMPERATURE
Satisfactory engine cooling
has
been
demonstrated for
this
airplane with
an
outside
air
temperature
230C
(41
0
F)
above
standard. This
is
not to
be
considered
as
an
operating limitation. Reference should
be
made
to Section
2 for engine operating limitations.
INTRODUCTION
TO
TABULATED
PERFORMANCE
The
performance
tables
are
presented in increments
of
temperature,
alti-
tude
and
any
other variables involved.
Performance
for a given
set
of
conditions
can
be
approximated
as
follows:
r=--........
(1 )
(2)
Takeoff, Accelerate Stop, Accelerate
Go,
Landing
-
Enter
tables
at
the next higher increment
of
weight,
altitude
and
temperature.
Cruise -
Enter
tables
at
next
lower
increment
of
temperature
and
altitude.
To
obtain exact
performance
values
from
the
tables,
it
is
necessary to
interpolate
between
the increment values.
The
following
is
an
example
of
approximation
and
interpolation, using
an
excerpt
from
the
Normal
Takeoff
Distance Chart.

Method
Extract
from
the chart the next increment
of
weight,
altitude
and
tem-
perature
which
is
more
conservative
than
the actual conditions
[i.e.:
6500
