Air India CRASH
"Not always so, unfortunately. During a simulator session the FMS was made inoperative prior to a VOR/DME approach. The purpose was to give the crew currency in using radio aids to navigation. The captain virtually downed tools and said it was not possible to carry out the instrument approach without the FMS. He was wrong. It was, but he did not know how to fly a straight forward VOR/DME approach including the DME arc. Later the FMS was restored but the IRS was unable to update and cockpit indications revealed the present position was actually 15 miles from the correct geographical position." Unquote
My comment about automation was related to the bravehearts who wanted to handfly from TOD to touch down.Also in your above example it is not quite correct to quote a simulator exercise because the aircraft and the sim behave quite differently and the guy at the back can make you lose Situational awareness in no time. Even by doing a simple thing like increasing speed at 2X ,inorder to cover more syllabus, you can put the trainee off and create loss of SA.
