I never use Auto pilot or automation. I only fly the A320 and C152. I like to be in full control of the aircraft at all times. With the A320, I’m never in the cockpit for long duration flights. Short hops from city to city. Jump in the C152 tour around, drone camera a bit around then back in the A320 to the next city. I never fly the A320 any more than 10,000 feet at any given time. My preference though is 5000 feet.
