Crab I think we need to remember that we are talking teaching new guys to fly here. So for instance hovering downwind will require more power as they are unable to hold a steady hover as into wind, different for a seasoned pilot. It is the same as making an approach, teaching downwind to a student ( lesson 26 ) one has to be careful what one teaches as they can struggle to process all the information coming into them ( helmet fire to use a UK mil term ) so best to teach a flatter approach so there is a little less going on. Remember within 45 hours they could be off on their own, with very little if any oversight !!!!
