Autopilots run the gamut from simple wing-levelers to fully automated departures, en route navigation, arrival procedures, landings, and runway rollouts. You'd be amazed what even a light piston single-engine can pack. Just today I flew a light single with an autopilot that can do climbs, descents, level-offs, en route nav, and precision approaches (lateral nav + glideslope) down to 200' AGL. That leaves maybe two minutes of the entire flight that require hand-flying, in a box the size of a small car stereo. Pretty good stuff.
