As an instructor I have practised , in my head at least , engine failures/partial engine failures , at the field I fly from on thousands of occasions.
I almost know every blade of grass within two miles of where I fly from. The slope/gradient/size of every field that is within glide distance after my runway is used.
I also train my students the same so that should it ever happen to them then they know where to go.
Happiness was seeing an EFATO from an examiner on the end of '20' and a right turn while trimming for best glide....'instinctive' was the word used. And it is the only available place to land should it go bang there !
