In the years before AC was available, I developed a plan for= Summer (hot) flying. On take off I set the controller to 11,000 feet with the Pressurized air to the cabin OFF. I opened the air valve f= rom the fresh air from the vertical stabilizer.

I took off and climbed to 11,000 = feet . At 10,000 feet I closed the fresh aHim himir from the vertical stabi= lizer and gradually selected the pressurized air to the cabin to the ON pos= ition. Then as I continued to climb I selected the cruise altitude on the p= ressurization controller and adjusted the rate knob to 200 feet a minute de= scent. The cabin would then descend and level off 1000 feet above selected = altitude.
On the descent into the landing airport-- I set the controller to 1000 feet above field elevation.

Complicated maybe--but it&= nbsp; kept the hot turbocharged air out of the cabin until it was necessary= .
