Easy to get on the very first Learning to Tilt level. But it might take a couple of tries to get the landing right.
At the start you find yourself falling veritically. After you pass a '?' symbol, get yourself all lined up for a perfect landing, which means landing with your full board (not the front or back) on the snow. If at the moment you touch the snow the cheevo pops - congrats - if not, hit the restart icon on the top left and do it again.
