All the parachute rigs that are used today by skydiving enthusiasts have six important parts.
The main canopy is just the parachute itself.
The drogue chute is a small parachute that is used by skydivers to open the main parachute. Skydivers have to throw out the drogue and when it catches the wind it will pull out the bridle, a piece of nylon webbing, then the bridle pulls out the main parachute.
The reserve is also known as the second parachute. This second parachute is available for the safety of skydivers just in case the main parachute won't open for any reason.
The container is attached to hold the main parachute and the second one in a very safety place.
Another important part in any skydiving equipment is the AAD. If anything wrong happens with the skydivers and they can't open the parachute, this AAD will automatically do it for them at about 800 feet.
