NOTE
If for any reason a test transmission is necessary, the test
transmission should be conducted only in the first five minutes
of any hour and limited to three audio sweeps. If tests must
be
made at any other time, the tests should
be
coordinated with the
nearest FAA tower or flight service station.
AIR CONDITIONING
*
To operate the air conditioning system either on the ground or in flight:
1.
Start the engine (ground operation).
2.
Turn the air conditioning "Master" switch to "ON."
3.
Turn "TEMP" control to desired temperature. Clockwise rotation increases cooling.
4.
Select desired "FAN" position, "LOW," "MED or "HIGH."
AIR CONDITIONER OPERATIONAL CHECK PROCEDURE
Prior to take-off the air conditioner should
be
checked for proper operation as follows:
1.
Check aircraft Master Switch ON.
2.
Select desired "FAN" position, "LOW," "MED" or "HIGH."
3.
Turn the air conditioner control switch to "ON"
-
the "Air Cond. Door Open"
warning light will turn on, thereby indicating proper air conditioner condenser door
actuation.
4.
Turn the air conditioner control switch to "OFF"
-
the "Air Cond. Door Open"
warning light will go out, thereby indicating the air conditioner condenser door is in
the up position.
5.
If the "Air Cond. Door Open" light does not respond as specified above, an air
conditioner system or indicator bulb malfunction is indicated, and further
investigation should
be
conducted prior to flight.
The above operational check may be performed during flight if an
inflight failure is
suspected.
AIR CONDITIONER EFFECTS ON AIRPLANE PERFORMANCE
4
Operation of the air conditioner will cause slight decreases in the cruise speed and range of
the Cherokee Arrow
11. Power from the engine is required to run the compressor, and the
condenser door, when extended, causes a slight increase in drag. When the air conditioner is
turned off there is normally no measurable difference in climb, cruise or range performance of
the airplane.
NOTE
To insure maximum climb performance the air conditioner must
be turned off manually before take-off 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.
