BOAC
Haven't a lot of pilots on this thread stated that they keep their hands on the throttles anyway during the approach, whether autothrottle controlled or not? Is this the "training out" you refer to?
Is it not a reasonable thought process that if you have just pushed the throttles forward, because they are not in the position they should be, as controlled by the AT, then it is sensible to make sure that they stay where you put them? Assuming no distractions etc etc.
