Looked like it was on flotation skis at least. The standard AW139 avionics wouldn't be my choice for VFR mountain weather flying, just an iPad with a map and elevation information is already an improvement. Might have had something better installed but generally public service helicopters cinched by budgets rarely do. I see EGPWS mentioned, but would be of little value unless IMC - in mountain VFR weather you already know you are close to the ground, slow, eyes out and the EGPWS is just an irritation unless you are using it like a second rate map trying to find a valley route.
Takeoff looked ok, didn't linger to try create a snowball, didn't go off in a direction he didn't need to trying to comply with some performance standard. Got away downwind without any performance problems. Weather was what you get in the mountains in winter, like 212man said "blameless".
Don't know the experience of the pilots, if they had done winter mountain stuff before like Swiss/Austrian/Italian operators in the Alps. That becomes an operational control issue - matching the equipment and crews to a challenging environment.
Tragic loss of life. Why so many people on board for a skier with a bum leg?
