Although the cruise speed and range are only slightly affected by the
air
conditioner
operation, these changes should be considere.d 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.
1. Decrease true airspeed - approltimately 5 mph at normal cruise power setting.
2. Decrease range - may be as much as 30 statute miles for 48 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.
PIPER AUTOMATIC LOCATOR
The Piper Automatic Locator, when installed,
is
located in the aft portion of the fuselage
just below the stabilator leading edge and is accessible through a plate on the right side of the
fuselage. It is an emergency locato.r transmitter which meets the requirements of FAR 91. 52. It
is automatically activated by a longitudinal force of 5 to 7 g's and transmits a distress signal on
both 121.5 MHz and 243.0 MHz for a period of 48 hours in low temperature areas to 100 hours
in
high temperature areas. The unit operates on a self contained battery.
The batte
r
y has a useful
life
of four years. However, to comply with FAA regulations, it
must be replaced after two years of shelf life or service
life.
The battery should also be replaced
if the transmitter has been used in an emergency situation or if the accumulated test time
exceeds one hour. The replacement date is marked on the transmitter label.
The unit has a three position selector switch placarded "OFF," "ARM" and "ON." The
"ARM" position is provided to set the unit to the automatic position so that it will transmjt
only after impact and continue to transmit until the battery power is drajned to depletion or
the switch is manually moved to the "OFF" position. The "ARM" position is selected when the
locator is installed at the factory and should remain in that position whenever the unit is
installed in the aircraft. The "ON" position is provided so the unit can be used as a portable
transmitter or
in
the event the automatic feature was not triggered by impact or to check the
function of the transmitter periodically.
The "OFF" position is provided for the purpose of changing the battery or if used as a
portable transmitter or teanning the unit if it should be activated for any reason.
NOTE
If
the switch has been placed in the "ON" position for any
reason, the "OFF" position has to be selected before selecting
"ARM."
If
"ARM" is selected directly from the ''ON" position
the transmitter will continue to transmit in the
"ARM"
position.
Attached to the unit is a portable antenna, provided so that the locator may be removed
from the aircraft,
in
case of an emergency, and used as a portable signal transmitter.
The locator should be checked during the Ground Check to make certain the unit has not
been accidently activated. Check by tuning a radio receiver to 121.5 MHz. If you hear an
oscillating audio sound the locator may have been activated and should be turned off
immediately. Reset to "ARM" position and check again to insure against outside interference.
