I've seen hundreds of threads but this now takes the cake. Bts, I applaud your willingness to explore this, but it's gotten into the theater of the absurd with this frame of reference business. I'm not sure Einstein dropping balls off a moving train could understand this. Worse, I fail to see the relevance to what people actually do on snow by wondering where the frame of reference is. Hip, ski, body, com, foot, head, blimp.
I guess i'd go with the moving blimp, uav, above the skier.
Skidude, mellow out.
Could be passive heel slide though! Pivoting around shovel.
What's the issue with the below? Other than it's actively steering? It's pretty simple.

Defining it is easy...I can stand there and show people...turn the leg in the hip socket, and the ski tip moves "in" across the skiers body...and the tail goes "out" away from the skiers body. The same move happens when we do a pivot slip, or a race style stivot...its easy, simple, and clear.
I have taught thousands of people this, taught hundreds of instructors on sessions this ...
The Blimp View:
These guys, Cloudgate, have been using UAV's (unmanned aerial vehicles), quad copters, to film stuff. They went to Loveland recently. I think we shall see this on the World Cup possibly this year or the Olympics. Just a guess. With the glacial pace which the IOC works it could be 5 years.
(their vimeo feed seems to have issues playing. Can't get some of the other ones to work.)
