BigEndBob,
Great idea; unfortunately there's often not time. Anyway, helicopters are different....which is why I often spend a bit of time demonstrating hovering, quickstops, how you'd get into a confined area, and basically the fact that we don't have to be more than a few feet above the ground to have a lot of fun.
We are not discusing the legality of trial flights here, and my comment wasn't intending to discuss the issue with you or anybody, the comment aimed to make sure whirlybird knows what is at stake if he does not brieff his potential students before the flight.
I agree. I don't want to get into legal issues, because that's a whole other huge subject. But for R22 helicopters at least, you HAVE to give some sort of briefing, even if it's only to tell a potentially cackhanded individual twice my size that if he shoves the cyclic sharply forward he will unload the rotors and probably kill us! But after that? More? How much more? I thought it might make for a useful discussion, that's all.
LEVC, by the way, just for the sake of accuracy, I'm not a "he"; I'm one of the other sort.
Not many of us here I know, so no worries.
