With only 80 hours R22, maybe the pax should stand outside of the a/c and watch from a distance. Frank Robinson is rumoured tohave said none of his family can go in an R22 unless the pilot has more than 200 hours. Don't know how true that is but I can see why.
But seriously though, why not go through everything you as a pax would expect to be told, post it on here, and see if everyone agrees. That way you get a checklist which is pretty thorough.
A couple of points to start with:- Do not walk aft towards the TR or out of view of the pilot.
Do not get out of the helicopter before the rotors have stopped turning if shutting down.
Do not interfere with controls under any circumstances.
Ask if they have any Al Quieda relatives!!!!(excuse spelling)
