We (in Oz) always taught jams, loss of control and loss of drive to all our students, commercial or private, and they nearly always went to touchdown. Only power terminated if Bloggs let it get away from himself at the last second.
A marvellous way to learn control of the aircraft and develop a "feel" for it. The most important thing we drilled into Bloggs' thick skull was:
DON'T LET THE NOSE COME UP!
By keeping the nose down, there is control of the speed and rate of decay of speed. Nose up, speed comes off fast, haul on collective to stop ground impact, nose of helo zips off to the right and you are in trouble.
Last year at FSI in the S76 sim, we were practicing tail drive failures. Crash Buddy elected to auto to the ground, and we would have survived. For my turn, I nosed over for speed and with some manoeuvering managed a smooth run-on at the nearby airfield, much to the surprise of the sim instructor.
So, for you junior QFIs, find a senior one who will run you through the scenarios to touchdown, and then pass it onto your students.
