On a bit of a tangent, I'd appreciate some elaboration of FlyinDutch's reference to the EFATO training scenario being unrealistic.
Can't see I wrote that but if I did not convey myself very clearly apologies.
What I said was that people need to be trained so that they can handle an engine failure off pat. To sex it up by teaching them to do some additional bits which may or may not stop the prop and by doing so gain a bit extra in the glide which follows would to me, seem to be counterproductive.
What you want is that people without any hesitation can execute those skills necessary to set up safely for an engine failure in the minimum of time, cause that is what matters after an engine failure. Especially an EFATO.
Sure enough if at some point you want to talk about what you can do extra if you have height and therefore time to make things even better great. However judging by people's basic flying skills there seems to be plenty of room for improvement in those before embarking on more esoteric forms of FL techniques.
