It’s nearly impossible to fix your alignment in midair, especially if your hands are back or your arms flail. If you’re out of balance when you leave the snow, you’ll certainly be out of balance when you return to it.
Incorrect If your weight is even slightly rearward when you reach the crest of a rollover, your skis will follow a straight or even upward trajectory as the ground drops out. As your skis’ tips go up, their tails will drop. As we’ve said before, when your skis get ahead of your body, you lose all control.
Correct As you approach a drop-off, shift everything forward, exaggerating the movements if necessary. Flex your ankles, and keep your shins in contact with your boot tongues. If you get air, suck your legs up to keep your skis clear of the snow, pulling your heels up and dropping your toes just slightly so your skis become parallel to the new, steeper slope.
