• Note •
To facilitate faster cabin cooling, prior to engine start leave the
cabin doors open for a short time to allow hot air to escape
cabin.
For maximum cabin cooling, set Airflow Selector to fan speed

Temperature Selector to recirculation mode. Additionally,
ensure the instrument panel and armrest eyeball outlets are
open. (See Figure - 1)

Section 5 - Performance
When the air-conditioner is operating the following performance
changes will result:
1. Brake Horsepower is reduced by approximately 6 BHP.
2. Takeoff Distance: Add 100 feet to ground roll and 150 feet to
distance over 50 foot obstacle.
3. Maximum rate of climb performance is reduced by approximately
50 feet per minute. For maximum climb performance the airconditioner
should be off.
4. Cruise performance is reduced by 2 knots. If maximum
