SUPPLEMENTS
NOTE
To insure
maximum climb performance
the
air
conditioner
must
be turned
off manually
before
takeoff to disengage the compressor and
retract
the condenser door.
Also
the
air
conditioner
must
be turned off
manually before the landing
approach in preparation for a possible
go-
around.
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
compressor
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
6 KTS
at all
power
settings.
(b)
The decrease in
range may
be
as much
as
40
nautical miles
for the
102 gallon
capacity.
The climb performance is not compromised
measurably
with the air
conditioner operating since the compressor is declutched and the condenser
door is retracted,
both automatically, when
34
inches Hg or more manifold
pressure
is
used. When less than
34
inches
Hg
manifold pressure is used or in
the event of a malfunction which would
cause
the
compressor
to
operate
and
the condenser
door to be
extended,
a
decrease in
rate
of climb of as much as
100
fpm
can
be expected.
Should
a malfunction
occur
which
prevents
condenser door
retraction when the compressor
is turned
off, a
decrease in
rate
of climb
of
as much
as
50 fpm
can
be expected.
