(a) Check aircraft master switch ON.
(b) Turn the air conditioner control switch to ON and the fan switch to
one of the operating positions - the ``AIR COND DOOR’’ warning
light will turn on, thereby indicating proper air conditioner condenser
door actuation.
(c) Turn the air conditioner control switch to OFF - the ``AIR COND
DOOR’’ warning light will go out, thereby indicating the air
conditioner condenser door is in the up position.
(d) If the ``AIR COND DOOR’’ light does not respond as specified
above, an air conditioner system or indicator bulb mal- function is
indicated and further investigation should be conducted prior to flight.
The above operational check may be performed during flight if an in
flight failure is suspected.
The condenser door light is located in the annunciator cluster in front of
the pilot. The door light illuminates when the door is open and is off when the
door is closed.
SECTION 5 - PERFORMANCE
Operation of the air conditioner will cause slight decreases in cruise
speed and range. 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
takeoff 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.
