I'm only a 40 hour helicopter student. I have found that the self disipline of sitting and tidying up the cockpit after a flight to be very relaxing, while the blades coast to a stop in their own time. That's what the operator's checklist says to do, and I do everything else on the checklist, why not finish the job properly?
I have not walked the mile in the other pilot's shoes, so I'm not critisizing, and I suppose there will be a time when letting it wind down on it's own will make some sense to me, but for now, I'm still a little scared of screwing up!
I'll wait!
