Throw-out
The throw-out pilot chute is the most popular type in use today. The pilot chute is packed in a pouch at the bottom of the container (often called BOC for short). The handle is attached to the apex of the pilot chute. When the user grabs the handle and throws the pilot chute into the airstream, the bridle extends, pulling the closing pin and opening the container, as the pilot chute continues in the airstream it extracts the deployment bag containing the main parachute from the container. The throw-out pilot chute was invented by Bill Booth.
