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.

statute miles for

gallon capacity.
When the full throttle is not used or in the event of malfunction which caused the
compressor to operate and the condenser door to be extended, a decrease in rate of climb of as
much as
100
feet per minute can
be
expected. Should a malfunction occur which prevents the
condenser door retraction when the compressor is turned off, a decrease in rate of climb of as
much as
50
feet per minute can be expected.
