Rig Systems That Provide a Safe Descent

From the outside, a skydiver's rig looks like a slim backpack. Inside it sits an entire safety system, built so that two parachutes can be deployed cleanly and the jumper stays securely attached from the moment they leave the aircraft to the moment their feet touch the grass. Understanding how it fits together helps any licensed jumper make better choices about their own kit.

What sits inside the container

A complete rig has four main parts working together:

• The container holds both parachutes in separate compartments, closed with flaps, loops and pins.
• The harness wraps around the shoulders, chest and legs, spreading the opening forces across the body.
• The main canopy is the parachute used on almost every jump, released by throwing a pilot chute.
• The reserve canopy is packed by a qualified rigger and used only if the main has a problem.

Small details matter enormously. The closing loop, for instance, keeps the main compartment shut until the pilot chute pulls the pin, so a worn loop can cause a premature opening. That is why gear checks before every jump look at loops, pins, handles and straps in a set order.

Safety features that back you up

Modern rigs layer several protections on top of the basic design. An automatic activation device, or AAD, monitors altitude and descent rate and fires the reserve if the jumper is still falling fast at a low height. Many sport jumpers regard an AAD as standard equipment, and many drop zones require one.

A reserve static line, often called an RSL, connects the main risers to the reserve so that cutting away a malfunctioning main helps deploy the reserve quickly. Some systems add a mechanism that uses the departing main to speed up the reserve further. Handles are shaped and coloured differently so they can be identified by touch under stress.

Choosing the right setup

Fit and suitability come before style. A harness that is too loose can shift during freefall or opening, while one that is too tight restricts movement. Canopy size must match the jumper's experience and weight, and student or newly licensed skydivers are usually advised to stay with larger, more forgiving canopies until an instructor agrees they are ready to downsize.

Many jumpers find that buying a matched skydiving rig package simplifies the process, since the container, canopies and AAD are selected to work together and sized as a set. It removes a lot of guesswork about compatibility, which is especially useful for anyone buying their first complete system.

Keeping the system in good order

Gear needs regular attention, and some of it is required by the rules of the national skydiving association:

1. Reserve repacks and inspections by a certified rigger at the required intervals.
2. AAD servicing and battery changes according to the manufacturer's schedule.
3. Checks for frayed webbing, worn closing loops and damaged grommets.
4. Dry, shaded storage away from sunlight and chemicals.

Skydiving always carries risk, and equipment is only part of the picture. Training, currency and sound judgement on the day matter just as much. A well-chosen, well-maintained rig gives a jumper the best foundation, so that every descent can end with a gentle flare and a walk back to the hangar.
