Ski Airmat Cork 540.

1. First, be able to land both a frontside 360 (toe-side pop, spinning forward one full rotation) and a backflip on the airbag consistently.

   A cork 540 is those two combined on a tilted axis.

2. Approach at a steady, moderate speed.

   Carry a little weight on your toe (toeside) edge, keep your upper body squared down the hill, and hold both arms loosely wound across your front so you have some twist to release at takeoff.

3. As you reach the lip, push straight up with both legs while starting the frontside rotation from your shoulders (for a regular stance, that means pulling your left shoulder back).

   Up to here it's the same entry as a normal FS 360.

4. Right after takeoff, drop your head and left shoulder toward your front-left and DOWN, not straight up.

   Send your eyes the same way, toward the snow ahead of your feet. Spinning sideways while tipping your head down-and-forward tilts your axis between vertical and horizontal, and that diagonal tilt is what makes it a cork.

5. Once the axis is tilted, pull both knees to your chest and tuck both arms in tight to your body.

   The smaller you make yourself, the faster you rotate on the same momentum, which buys you room to finish all 540 degrees.

6. When you're about halfway around and the bag (or landing) comes into view, release your knees and arms and open your body out.

   Spreading your limbs slows the spin so you can stop the rotation and line up your direction.

7. With your direction (facing forward) in sight, land on both feet together.

   The airbag forgives an off axis, so prioritize completing the rotation first and refine your landing posture later.
