Just Joined,
Agree totally on comments about not setting zero thrust until student has signified the failed engine has been feathered.
I get the student to actually move the pitch lever one inch while I guard the lever against moving past the gate. This is so they don't get into the habit of merely touching the lever; very dangerous if they revert to this behaviour in an actual emergency. (Don't laugh, I've seen it happen!)
If they forget to "feather" the failed engine, the experience reinforces the completion of the EFATO drill. Continued loss of height is a strong incentive to get it right.
"Whay are we losing height, Bloggs? Repeat the drill."
Similar pitfalls include forgetting to clean up the airframe (eg. leaving gear down during a go-around and not manging the live and securing the dead engine.) These drills MUST be practised IN THEIR ENTIRITY until they are second nature.
