A3757 is quite right. Situational awareness is key. I wonder how many ''automated'' pilots bother to identify the localizer frequency. Garbage in Garbage out.
Oh, and that NW Airbus that overflew Minneapolis...it didn't take care of itself.
I do think one problem with autopilot use, especially in emergency ops in simulator training is this. .Union contractual language doesn't allow for compounding emergencies during check rides. Lose an engine and they can't fail the autopilot on you...in the sim. But in real life, well that's different.
