Airplanes use a variety of modes of autopilot systems and some modes absolutely do not require the pilot to touch the controls. They do require the pilot to set the mode and its parameters in the first place, and it would usually be considered a serious safety violation if both pilots were to get up and leave the cockpit while autopilot was engaged, but the technology is definitely good enough to handle this situation. This is not true for Tesla's FSD. Not by a longshot.
