            Basic Safety Requirements - The basic rules created by the USPA

            A throw-away pilot chute is kept in a pouch on the right
            leg strap.  The pilot chute has a handle at the top which
            sticks out of the pouch when folded up to give you something
            to grab on to.  The pilot chute has a bridal attached, which 
            is routed to the main container and connected to the bag.
            The bridal also has a pin attached to it (curved) about 12"
            from the bag which is used to hold the main container closed.

            To deploy a throw-out/away, you simply pull it out of the pouch
            and throw it into the air.  The pilot chute inflates, pulls the 
            pin out of the closing loop, and then pulls the bag out of the 
            container, releasing the lines from their stowes.

            A pull-out pilot chute is similar but there are some key 
            differences.  A pull-out has a soft handle (pud - similar
            to a cut-away pud) on the bottom right corner of the container.
            This handle has a short bridal with a closing pin (straight)
            about 12" from the handle. Past the closing pin, the bridal
            attaches to the pilot chute (which is tucked under the flaps
            of the main container) and then to the main bag.

            to deploy a pull out, you simply pull the handle which
            immediatly extracts the pin and releases the pilot chute.
            In the same motion, you throw the pilot chute into the wind
            and the deployment continues just like a throw out.

            The big difference (which most jumpers have an opinion on)
            is that in the pull out system, YOU gaurantee that the pin
            is pulled, while in a throw out, the pilot chute pulls the
            pin.  There are pros and cons to both systems.  If you want
            to start a flame war, just post some comment that makes one
            system seem better than the other, and duck.....
