SECTION 3 - EMERGENCY PROCEDURES
No changes to the basic Emergency Procedures provided by Section 3
of this Pilot’s Operating Handbook are necessary for this supplement.
SECTION 4 - NORMAL PROCEDURES
Prior to takeoff, the air conditioner should he checked for proper
operation as follows:
(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 “AIRCOND DOOR OPEN”
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 OPEN” warning light will go out, thereby indicating the air
conditioner condenser door is in the up position.
(d) 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 in
flight failure is suspected.
The condenser door light is located to the right of the engine instrument
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.
