Although the
cruise
speed
and
range are
only
slightly
affected
by
the
air
conditioner
operation,
these
changes
should
be
considered
in
preflight
planning. To be
conservative,
the
following
figures
assume
that the
com-
pressor
is
operating
continuously
while the
airplane
is
airborne.
This
will
be
the
case
only
in
extremely hot
weather,
(a)
The
decrease
in
true
airspeed is
approximately
4
KTS
at
all
power
settings.
(b)
The
decrease
in
range
may
be
as
much
as
25
nautical
miles forthe93
gallon
capacity.
(c)
The decrease
in
range
may
be
as
much
as
35
nautical miles
for
the
123
gallon
capacity.
Climb
performance
is
affected
by the
air
conditioner
operation.
A
decrease
in
the
rate
of
climb
of
as
much
as
80 fpm
can
be
expected
at
all
altitudes
with the
air
conditioner
operating.
