Don't be a DICK!
What not to do on the dropzone...
Learn to adjust your fall rate while flying on your back. Learning the back flying upward and downward movements will provide you with the ability to adjust the altitude you are flying at. Being comfortable at gaining altitude in the tunnel on your back will also help lead you in to more advanced trick moves during your flight progression.
The primary objective is to be able to safely and successfully demonstrate that you can fly up and down while back-flying. You will need to demonstrate that you can perform these maneuvers while remaining in the center of the tunnel the whole time.
Upward and downward movements (fall rate control) are important aspects of learning to back fly. Understanding these techniques will serve you well throughout your Freeflying progression. From this point forward, your progression will demand higher wind speeds to be able to fly so understanding how to control your body at any wind speed and move to any altitude will provide a safer more learning rich environment for you.
