What Do Pilots Do When A Plane Is On Autopilot?

An automatic flight control system is described as dumb and dutiful. The success of the autopilot depends on the knowledge of the actual human pilot. Autopilot isn't as "auto" as you might think. It lets a pilot fly without white-knuckling the controls. Like a polar bear, autopilot functions through a negative feedback loop. The video incorrectly states the direction in which single-axis autopilot guides the plane. The single-axis autopilot keeps the wings parallel to the ground, not perpendicular. Insider regrets the error.
