actually, depends on the aircraft. If you are flying a C172, then yeah, you are right.
OTOH, the AP in 747 and 380s make choices ALL THE TIME. Those APs are capable of taking off, flying the whole way to the end route, and then landing. And those APs make LOTS AND LOTS of choices. Hell, on Airbus, the pilot is NOT IN CONTROL. The Computer, otherwise known as the Autopilot, is actually in 100% control unless the AP or pilots disengage it, which is damn rare. The pilots are simply INPUTS into the computer. In fact, because of Airbus's poor software and design, that is what caused multiple crashes by pilots putting in conflicting inputs and the computer than making bad choices.
