SECTION 9
SUPPLEMENT 1
PIPER AIRCRAFT CORPORATION
PA-28R-201, ARROW
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
72 gallon usable fuel 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
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 at all altitudes. 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.
