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 32 nautical miles for the
48 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 a full throttle position is
selected. When the full throttle position is not used or in the event of a mal-
function 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.
SECTION 6 - WEIGHT AND BALANCE
Factory installed optional equipment is included in the licensed weight
and balance data in Section 6 of the Pilot's Operating Handbook.
SECTION 7 - DESCRIPTION AND OPERATION
No change.
