Regarding this "old chestnut" I have often thought that ever since the dawn of flight training the tyro pilot has always started on single engined aircraft. Thus there was the dogmatic insistance for applying speed with elevator etc. to safely fly any engine out landing, and thus much training time is devoted to this exercise.
However, with power available other options avail themselves! John Farley, in his excellent book, tells an amusing story about his rebelling against this very same dogmatically taught technique whilst he was a student QFI at CFS. Well worth a read!
