As I see it happening in real life, the first thing that you have to do before putting emergency landing training into practice is to decide that you are going to put this very nice aircraft onto the ground away from an airfield. How do you make that decision correctly?
My one partial engine failure, the instructor took control, told me where was aiming for, sorted out the glide. Then we both started checking for what was wrong, and found it and fixed it. All exactly as per text book and training, and it all worked fine, and it was over in tens of seconds.
