One more opinion for the ravens to pick at:
Many years ago, when I was an active CFI at a small College, I became aquainted with the "Distract the student and turn the fuel selector off" trick. Before hand, I had had throttles and mixtures pulled, and once had a mixture control broken in the full lean position by the instructor during my multi training.
I wasn't too enamored of the fuel shutoff method at first, but I tried it with a few students who had already been exposed to several sessions of "normal" engine-out training. What changed my mind about the usefullness of this procedure in a
carefully controlled manner was the
SHOCKING number of students who would do the drill, touching the selector/shutoff, mixture, mag switch etc,
but never actually looking at the selector and verifying it was ON!!! Some just about totally freaked out at the engine stopping without any apparent action on my part. Many I had to promt to check everything twice, and STILL didn't notice the fuel selector off.
I want to stress that I only did it on small, carburated engines in our C-150/152 fleet, and that I always had lots of altitude when we began (normally practicing stalls and associated clearing turns), I always already had a suitable landing area picked out in case the engine HAD failed to re-start, and I never carried this exercise below about 1000' without re-starting the engine, and then perhaps continuing the drill to an appropriate altitude using throttle alone. I would never advocate anyone trying this on high-horsepower, hot running, fuel injected engines for many of the reasons already enumerated.
I feel very strongly that the exercise, used
judiciously , has merit. I think all those students learned something usefull beyond a simple flow or memorized procedure. It made them actually USE those procedures in a real (to them) emergency, and show them that they actually had to THINK and DO the checklist items, not just follow a script. It also made them think about what keeping their wits about them really meant.
I'm not about to set any aircraft on fire though.....
