Boeing 777 Crash: Asiana Says Pilots Blindsided By Autothrottle
The U.S. National Transportation Safety Board might be six months from declaring the probable cause and contributing factors in the Asiana Airlines 777-200ER crash in San Francisco last July, but two main participants in the investigation, Asiana and Boeing, have already formed their own conclusions.

They were also blindsiding by the lack of the inability to fly the plane straight on a CAVU no-wind beautiful sunny afternoon.
* lack of manual piloting ability

Same auto throttle system as the 747-400 the Capt flew previous.
Asiana you can't really try "saving face" on this one. Your pilot and your training were NOT up to the job teaching someone how to fly a Triple 7. You should have let Boeing train them.

The pilot training had spent too many years on the A320. So his brain got reprogrammed to be a lazier pilot. That previous 747 experience was years earlier. On their airline, the first officer isn't really a co-pilot as much as an assistant/ systems manager to the captain, who's the pilot.
That doesn't excuse the instructor pilot, who had thousands of hours on type, and should know about the FLCH Trap.
FLCH wasn't made for use on final approach. At altitude, you wouldn't necessarily want your engines to throttle up if you're already in the process of descending to a lower altitude.
At very low altitudes, as the pilots pull up the nose to decrease vertical speed, their airspeed will also decrease. In this case, the pilots allowed their airspeed to decay to stall speed. Then stalled the plane by quickly raising the nose of the plane without sufficient airspeed or sufficient thrust to create lift.
In essence, they flubbed their landing, destroyed their plane and killed and maimed passengers.
Their performance was reflective of incompetence in their professional duties. Anything an everything they could get wrong, they got wrong. There were many things they could've changed and gotten right. Any one of these many actions, had any one of them been performed proficiently, would've avoided a catastrophic crash.
