Thanks to those correcting my English, I think static line is what I meant.
Well, interesting answers, thanks a lot.
My friend is a jumper and he wants to try a static jump from an AS350. Static line is 7 mt long. I've not calculated but 7 mt seems very long for the size of the 350, even if somebody from the cabin is recovering the lines and the helicopter is virtually hovering (yes, a bit of fwd speed would be beneficial).
I'll take a moment to make some measurement on a real 350, please let me know if any of you have interesting suggestions.
