mixmaster Posted March 14, 2009 Report Share Posted March 14, 2009 Hi to all. Been floating around here for a couple of years and not really posted that much, but I do find this forum to be a great resource. I am from down south and really the the mountains around here are more hills (less that 3000 ft) but i have been following a couple of the threads (the heli logging one, also watching on TV and the heli skiing one). Anyway a quick question for the more experienced among us. At what point does wind go from being helpful to dangerous to deadly in the high mountains (think above tree line, heli skiing, Canadian Rockies, Colorado Rockies, Sierras, Utah, etc). What about the type of rotor system (Bell 206B/L, 205/212 vs Astar, 407, 412) and how does that change the equation. I know every situation is different, but around here hills are 500 to 1000 ft above surrounding area and not really craggy, just rolling hills, so up to 30-40mph is good to go as not too much turbulence. How does the really high stuff, or mountainous terrain (cliffs, cirques, pinnacles, knife edge ridges, etc) change things and when do you shut it all down. Attending a mountain course (the best ones are in Canada from what I hear) is the best way to find out, but that is out of the question for now. Thanks in advance for any informative reply's.
