I'm with Pace on this one.
P Classique
My comment was a broader one than just specific to this thread and shutting this particular engine down. Obviously anything done for real will carry more risk and if you look at my original post it did add (if you survive)
But then if anything happens for real later in your flying it will carry more risk than if you have never experienced it before.
The biggest fear of all is fear of the unknown and if pilot are taught and left with a big dollop of unknown they are not confident pilots and this goes for full stalls spins strong winds, shear, icing etc etc etc i.e. all the things we will probably deal with later on our own.
nut yes if you are going to teach something with an element of risk take all precautions to minimise that risk.
